Did your furnace break down suddenly? Sometimes, the problem may be simpler than you think. Resetting your furnace is a common solution that can restore warmth to your home.
This guide will walk you through the steps to reset your furnace safely and explain when it’s appropriate to do so.
Why Your Furnace Might Need a Reset
Before diving into the steps, it helps to understand why your furnace might need resetting.
A reset is often necessary due to safety features kicking in, small malfunctions, or even power outages.
Here are a few common reasons we see:
- Overheating: If your furnace overheats, it will often shut down automatically for safety reasons. This can happen if airflow is restricted or if debris is building up.
- Power Interruptions: When a power outage or surge occurs, your furnace might shut off or display error codes requiring resetting.
- Faulty Ignition or Flame Sensor Issues: Furnaces rely on igniters and flame sensors to function correctly. If an issue occurs, it can trigger the need for a reset.
- Fuel Supply Problems: In gas furnaces, a sudden stop in fuel supply might cause the furnace to lock out until manually reset.
Steps to Safely Reset Your Furnace
If you suspect your furnace needs a reset, follow these steps. Prioritize safety and never attempt repairs beyond your comfort or expertise.
For major issues, consult a professional HVAC technician.
Turn Off the Power Supply
Locate the power switch for your furnace and turn it off. It’s usually a switch on or near the furnace unit, similar to a light switch.
If unsure, you can also turn off the circuit breaker that controls the furnace.
Wait for a Few Minutes
Leave the furnace off for 5-10 minutes. This will allow any lingering issues to clear and give your system a chance to “cool down.” This brief pause will help reset internal components.
Find the Reset Button
Check the body of your furnace to find the reset button. Typically, this button is red or yellow and located on the blower motor housing.
Not all furnaces have a visible reset button, so refer to your owner’s manual if needed.
Press and Hold
Firmly press and hold the button for 10-30 seconds. You may hear a click or feel a slight pop as you press. Once released, this tells the furnace to attempt to restart.
Restore Power and Test the Furnace
Turn the power switch or circuit breaker back on.
Next, set your thermostat to a temperature higher than the current room temperature and wait a few minutes to see if the furnace ignites and resumes normal operation.
When to Call an HVAC Professional
If your furnace fails to restart after attempting a reset, a deeper issue may be at play.
Persistent problems such as frequent resets, strange noises, or irregular heating often indicate a need for professional assistance.

To minimize the likelihood of needing to reset your furnace, keep up with regular maintenance and inspections. This can include:
