Where Is The Reset Button On Furnace?

Before it gets too cold, it is highly suggested to contact a professional HVAC specialist for furnace inspection in Severna Park. With a functional furnace, you can maintain a comfortable interior temperature during winter.

Alternatively, if your furnace fails, you may soon find yourself living uncomfortably indoors. Due to this, it is necessary to identify and resolve any problems involving your furnace as quickly as possible.

1. What is a Furnace's Reset Button?

Every furnace is equipped with a button to reset the unit. Red or yellow, they are typically seen inside the blower chamber. When a problem, such as a hot or overheating furnace, is detected, the reset button is a safety feature. It shuts down the furnace before it reaches the circuit breaker.

It is not uncommon for a furnace to require the control panel to be reset occasionally. However, if the furnace needs to be reset frequently, you should get it inspected by a specialist performing furnace repair in Severna Park. Contact an expert and appropriately licensed HVAC specialist, from J.S. Corcoran Heating and Air Conditioning.

2. Location of the Reset Button on the Device.

The manufacturer and model of your furnace will indicate where the reset button is located. The reset button for your central heating and air conditioning system is found on the blower motor. If these systems are installed in your residence, it is typically bright red or yellow to grab attention.

The location of the blower motor varies on specific models. The reset button may not be readily apparent. To locate the switch that restarts the motor, you may need to reach the rear and the bottom. After finding the reset button, you must keep it down for up to a minute and a half until the furnace is reset.

3. How Does a reset button work?

Inside the furnace’s blower chamber is typically a button to reset the appliance. The red or yellow display makes it very easy to identify. The fundamental purpose of a reset button is to serve as a safeguard for the user. When the furnace temperature reaches a harmful level, it aids in cutting off the heat. Therefore, the furnace will not trip the circuit breaker even if it becomes excessively hot.

A furnace may occasionally require resetting, such as when it becomes excessively hot. When this occurs, it is wise to push the reset button. Alternatively, if your heating system is repeatedly resetting itself, it is most likely that the button to reset it is being mistakenly hit due to a fault. Google
furnace check-up near me’ online, if you encounter issues.

4. Resetting an Electric Furnace.

  • Press the button to power down the device. If you cannot find it, you must turn off the circuit breaker directly connected to it.
  • After opening the blower housing, the reset button may be located within.
  • Please press the button and hold it until a click sounds.
  • To turn on the furnace, you must flip the circuit breaker.
  • The heating system will begin operating as soon as it receives commands from the thermostat.

What Are The 10 Most Common Furnace Problems

Surviving the freezing winter season in Severna Park is intolerable without an effective heating system to cool down your home. So, if your furnace unit is demanding frequent repairs, it is better to call experts for an HVAC tune-up in Severna Park to avoid any significant breakdowns.

Some Common Furnace Issues That Many Homeowners Face

Below are some of the most prevalent issues your furnace might face over time.

  • Dirty or Clogged Air Filters

A clogged or dirty air filter is a prevalent cause of furnace breakdown. So to avoid this issue, it is prudent to get the air filters changed every three months or as per the manufacturer’s instructions.

  • Thermostat Issues

One easy solution is to ensure that your furnace thermostat (which controls the temperature in your house) remains turned on and that the inside is clean and set to the right temperature. If the problem persists, it could indicate something more severe.

  • Refrigerant Leaks

When the furnace’s refrigerant leaks, the machine will stop working adequately, causing temperature changes. Since the degree of the leak affects the cost of repair, it is better to have it inspected out once a year by competent HVAC contractors in Severna Park.

  • Drainage

Like the furnace air filters, usually, the drain line also gets clogged with trash, dust, and lint. The drain pan will fill up if it becomes obstructed, and water will pour out, potentially causing damage to the heating system or whatever remains situated near the pan.

  • Breakers or Fuses

One of the initial points a heating and cooling expert looks for when a furnace breaks down is the breaker. Breakers and fuses guard the compressor or the engine of your furnace from overheating.

  • Capacitors

The engines that drive the compressor and furnace fans won’t operate without capacitors. The beginning capacitor sends a single jolt to initiate the motor, while the run capacitor transmits a series of jolts to keep it running. So if any one of these elements burns out, the furnace unit will not function properly.

  • Compressor

The compressor applies power to the refrigerant for better heat exchange and drives it through the coils. So when the compressor fails, the furnace will not heat your home.

  • Evaporator Coils

With a series of air ducts, evaporator coils gather cold air and return it to the house as warm air. However, when these coils break down, your furnace will malfunction.

  • Condenser Coils

As the compressor and condenser coils remain situated outside, they can become dirty due to the weather. So it is better to clean them regularly with a hose or call experts for routine servicing.

  • Worn Contractor

The blower motor, compressor, and condenser fan motor have contactors in a furnace. They join the compressor and motors to an electrical source, which switches them on. When the contactor turns and pits, it becomes challenging for the electric current to trigger the engines.

Why Your Furnace Is Not Lighting Up?

The ‘click’ sound that a furnace makes when it switches on is satisfying for furnace owners. But all the satisfaction goes down the drain when your furnace does not generate heat, and the house remains dead cold. Now, what can you do?

A malfunctioning furnace is extremely common. You can contact any of the leading HVAC contractors in Severna Park to fix your furnace. If you want to check your furnace yourself, here are some troubleshooting tips that you can checklist before contacting a professional for help:


Your thermostat decides what the house temperature should be. It instructs the furnace of the right temperature, and the house warms. However, if your thermostat does not detect the desired temperature, your home will either remain cold or become scorching hot.

Both situations are problematic for you. There are two solutions to this issue. First, check your current thermostat regularly for its batteries and wirings, and contact your technician accordingly. Second, if you do not have the time to give your current thermostat, install a smart thermostat that will understand your temperature requirements after a few days and control the furnace accordingly.


The breaker supplies the main power to the furnace. Sometimes, the breaker trips due to voltage differences. The tripping of the breaker protects the furnace from damage due to excessive current flow.

Go to the circuit and check the breaker. If it has tripped, you will have to replace it with a new one. Ensure to buy the right size breaker or ask your technician for furnace repair in Severna Park.


Check the furnace switch if the breaker is functioning well, yet the furnace does not light up. The switch should be near the furnace and easy to locate. Ensure that the switch has no breaks or tears on it.

Air filters

Air filters are an extremely important part of the furnace. Filters ensure that the indoor air is free from allergens, bacteria, viruses, dirt, dust, and pet hair. Moreover, air filters create a smooth airflow path from the system to the house and vice versa.

If the air filters are dirty and clogged, the indoor air quality will significantly fall. Also, the system will have to work harder to push the air into the home due to blocked paths. If you do not clean your air filters regularly, they may force the system to break down due to excessive working.

Flame Sensor

As the name suggests, the flame sensor senses the flame and helps in lighting up the furnace. If the flame sensor is faulty or dirty, it will not function properly and cause the whole system to suffer. All you need to do is clean the flame sensor and put it back in its place.

These troubleshooting tips should be enough to help you fix your furnace. But if the problem persists, you should contact an HVAC company for a furnace check-up near me. J. S. Corcoran has helped thousands of families fix their furnaces and other appliances with different problems. You can contact us at (443) 250-9917 or email us at to know about our services and rates.

9 Signs That Your Furnace is Dying

With everything going on in the world right now your furnace may be the last thing on your mind. However, it’s critical to keep your furnace in good working order, so you don’t have to worry about it later. But how will you know when something isn’t working?

Here are some obvious indications that your furnace isn’t working properly and needs to be repaired or replaced permanently:

  • The Cost of Heating is Rapidly Rising

It’s possible that the furnace is exhibiting signs of wear and tear and isn’t operating as well as it once did. A blocked filter makes a furnace work harder to draw air through it. Therefore cleaning filters regularly will minimize furnace run time and make it more cost-effective. Try the furnace repair, Severna Park.

  • Changes in Pilot Flame Color

The pilot light should be a deep blue color when your furnace works properly. If your furnace’s pilot light turns yellow, it signifies there isn’t enough air in the system, resulting in incomplete combustion. So be cautious and take all necessary precautions if the pilot flame changes shape or color.

  • Strange Noises

If your furnace starts making screeching noises, especially metal scraping metal, something is probably loose and needs to be fixed right once. Ignoring these sounds may result in more costly repairs in the future.

  • Dry or Dusty Air

If you notice more dust, dander, soot, rust, or filth accumulating in your home while your furnace is running, it’s time to replace or repair your system. Your furnace could be to blame if you’ve noticed your home’s air is arid.

  • Increased Health-Related Issues

Furnaces emit a lot of carbon monoxide, which is dangerous to your health. One of the most common sources of this hazardous gas is your furnace. While a well-tuned furnace will not cause this issue, a faulty furnace may.

  • Soot

When you use your furnace to generate heat, it burns fuel, particularly natural gas, and there are residues left over when the process is completed. Carbon, the principal element in black soot, is one of the combustion byproducts sent up the heat exchanger and out of the house. One of the symptoms that your furnace is failing is the presence of soot.

  • High Furnace Age

Do you believe your furnace will last indefinitely? If your furnace is more than 15 years old, you should consider furnace replacement choices. The problem with heating systems surviving longer is that their efficiency is often reduced after 20 years, even if they still operate.

  • Inconsistent Heating

Do you notice hot and cold patches as you move through your house? Your furnace is most likely the source of the problem. As your furnace gets older, it may become more difficult to distribute heat uniformly throughout your home, resulting in a more uncomfortable environment and higher energy bills, so search for a furnace check-up near me.

When any of the following indicators appear, respond quickly and take the necessary safeguards before it’s too late. JS Corcoran Heating & Air Conditioning is here to help you. Feel free to contact us at (443) 250-9917.

Important Benefits Of Furnace Cleaning

It’s important to keep up with furnace cleaning during the heating season if you want to keep your home warm. The parts inside your blower compartment are vulnerable to dust and dirt, which can weaken the entire system and cause safety issues.

At the very least, knowing how to change the system’s air filter will go a long way towards keeping it clean. When it’s frequently running, check it once a month. Replace it with a filter that’s right for your system and the exact size the manufacturer recommends, so you don’t have to clean your furnace as often between expert maintenance appointments.

Based on your skill level and comfort with mechanical systems, you might be able to clean parts of the furnace components yourself before and throughout the heating season. If you’re not comfortable working around the furnace or can’t get to its key sections, Corcoran Heating and Air will assist you with a full system cleaning and tune-up. Book an appointment with us for an HVAC tune-up in Severna Park today.

This blog will go over all of the advantages of having a furnace cleaned so that you can be warm and worry-free this winter.

  • Lower Utility Bills

You’re probably aware that clogged ducting reduces HVAC efficiency and increases utility bills. Clean ductwork, on the other hand, can reduce utility bills and maximize efficiency. That’s why it’s critical to have your home’s ducts cleaned every two years. If you keep up with a regular air duct cleaning plan, your ducts will remain free of hazardous particles that might bog down your system.

  • Increased Security

Safety is always the top priority when it comes to your family and home. Cleaning and adjusting the burner assembly, cleaning the ignition assembly, cleaning or changing air filters, inspecting the heat exchanger, and testing safety controls are all important to ensure security. You can heat your home without worrying about any safety hazards if you conduct a thorough inspection and cleaning.

  • Improved efficiency

The furnace needs to work harder when dirt covers the blower motor, switches, heat exchanger, and ignition system. A clogged filter would limit the amount of air passing through the heat exchanger, causing your furnace to run in longer cycles. Since dirt insulates the heat exchanger, a vital and expensive component of furnaces, the air blowing over won’t absorb as much heat, extending the time it operates.

  • Extended lifespan

Although furnaces are designed to produce heat, unclean parts such as the blower motor and fan, electrical switches and controls, and the heat exchanger accelerate the aging process.

  • Repairs Are Less Frequent

Cleaning, lubrication, and inspection of your furnace ensure that it operates at full efficiency, resulting in fewer malfunctions or difficulties. Because of this, your furnace will need lesser repairs.

Interpreting Solid Red Light On Furnace

If your oil furnace is not turning on, you could notice a solid red light on the burner unit. hen this red light, also known as a lockout light, glows, it means that a safety system on your furnace has forced a close down due to finding a problem or recognizing a malfunction.

Reasons For Solid Red Light Appearing

The lack of a flame when the burner is on is the most typical cause of a furnace shutdown, but there are numerous additional possibilities, or it could merely be a fluke. If your furnace has a visual display that shows a fault code, you may quickly examine the fault code to determine the cause of the issue. Look into the furnace manual to understand the meaning of the fault code.

If you do not have a digital display, there are a few things you should look into before pressing the reset button or calling for repair –

  • If There is Oil in The Tank

If no oil reaches the furnace, it will not fire, resulting in furnace suspension. Check the oil gauge to ensure you have enough oil, and if you don’t, call for delivery. Consider signing up for automatic delivery to avoid this from occurring anymore. You won’t be worrying about forgetting to fill your tank this way.

  • Check if The Oil Valve is Open

A shut oil valve stops oil from reaching the burner and thus hinders it from firing. The furnace will close down if no flame is detected. Open the valve if it’s closed.

  • Press The Reset Button

Usually, the reset button and the red light are the same buttons, although this is not always the case. If they aren’t, the reset button is generally nearby. Press and release the reset button to check if the furnace will ignite.

If it does, and it only happened once, it was most likely a fluke. However, if your oil furnace continues to shut off, DO NOT REPEATEDLY PRESS THE RESET BUTTON. Contact a professional HVAC contractor immediately because this is a symptom of a more grave condition.

  • Regular Furnace Maintenance

The automated shutdown of your furnace is a security measure devised to protect you and your furnace from further harm caused by the problem that made it close down in the first place. Many of the reasons for a breakdown, such as a clogged filter or a malfunctioning fuel pump, can be prevented if your oil furnace is tuned up once a year. Your HVAC tune-up contractor will ensure that all parts are clean and working correctly, providing you with a sense of safety during the heating season.

How Do You Reset A Goodman Furnace?

We often hear a renowned brand name when it comes to household furnaces, yes – it’s the Goodman Furnaces. With exceptional quality and affordability, Goodman furnaces are leading the home heating industry. Moreover, it also offers premier warranties such as replacing the entire furnace as the case may be. Ensuring a smooth operation, Goodman furnaces have safety measures such as primary limit switch, rollout limit switch, and lockout mode.
Some of these safety features reset automatically while some require manual operation. No one wants to shiver in the biting cold as the furnace stops working. Hence, we hastily tend to call for a furnace repair in Severna Park. Well, the good news is, it is a matter of a few minutes to reset your Goodman furnace.

Primary Limit Switch

Located on the partition panel, the primary limit switch will monitor the temperature of the heat exchanger. The limit switch will kick into action when the system detects overheating of the furnace. However, the primary limit switch is programmed to reset on its own. In case it doesn’t do so, you can always search for a furnace check-up near me and get the necessary help.

Rollout limit switch

This safety switch monitors the burner flame and is located on the burner assembly. When the flame is not properly drawn into the heat exchanger, the rollout limit switch gets activated. Unlike the primary limit switch, this has to be reset manually for the furnace to resume operations. Here is how you can reset the Goodman furnace rollout limit switch:
Step 1
Before performing any resets, always ensure that the furnace is not receiving any electrical supply. For this, flip the circuit breaker switch to the ‘off’ position and proceed further.

Step 2
Remove the access panel of the furnace so that you can access the internal components. This can either be done by lifting the panel sides or by removing screws from the panel. This differs as per different models of the Goodman furnace.

Step 3
Inside the burner assembly, look for the rollout limit switch. Hold the red reset button for a few seconds and release it. Turn on the circuit breaker switch and check if the problem has been solved. Otherwise, you may need to call a furnace repair in Severna Park.

Resetting The Lockout Mode

If unable to ignite within 3 attempts for a single heat call, the Goodman furnace goes into a lockout mode. Unless reset manually, the furnace will not attempt to run again. The furnace will reset by:

  • Automatic reset by the integrated module after 1 hour of lockout
  • Cut off the power supply for 30 seconds or more
  • Lower thermostat for a brief period and return to previous settings

If the situation persists, you may have to look for a furnace check-up near me. J.S. Corcoran Heating and Air conditioning specialize in all kinds of furnace services such as repair, maintenance, and installation. Call today at (443)-250-9917 and get quality service for your Goodman furnace.
