If you have a carrier furnace in your home, you may encounter some problems that affect its performance or safety. For example, your furnace may not turn on, blow cold air, make strange noises, or display an error code.
In some cases, these problems can be solved by resetting your furnace. Resetting your furnace can restore its normal operation and clear any minor faults or glitches.
But where is the reset button on a carrier furnace? And how do you use it? In this blog post, we will show you how to locate and use the reset button on your carrier furnace.
What is the Reset Button on a Carrier Furnace?
The reset button on a carrier furnace is a small red button that is located inside the blower compartment of your furnace. It is usually near the bottom of the furnace, on the side or back. It may also be mounted on a sheet metal above the burner area.
The reset button is connected to a safety device called a limit switch, which monitors the temperature inside the furnace cabinet. If the temperature gets too high, the limit switch will shut off the gas valve and stop the burner from heating. This prevents overheating and fire hazards.
The reset button allows you to manually restart the gas valve and the burner after the limit switch has been tripped. However, you should only use the reset button if you know what caused the limit switch to trip and have fixed the problem. Otherwise, you may damage your furnace or cause a safety hazard.

When to use the reset button on a carrier furnace?
You should only use the reset button on your carrier furnace if you are sure that it is safe and necessary to do so. Some of the situations where you may need to use the reset button are:

- A tripped circuit breaker or a blown fuse that cuts off power to your furnace.
- A dirty or clogged air filter that restricts airflow and reduces heating efficiency.
- A low gas pressure or supply that prevents your burner from igniting.
- A dirty or damaged flame sensor that fails to detect the burner flame and shuts off the gas valve.
- A faulty blower motor or fan that fails to circulate air through your furnace and ductwork.
If you cannot find or fix these problems yourself, you should call a professional HVAC technician to help you. Do not attempt to repair your furnace if you are not qualified or experienced to do so.
