How To Reset a Carrier Furnace Unit

When the lights go out in Arizona, California, Idaho, New Mexico, Nevada, or Texas, your furnace might too.

If your Carrier furnace doesn’t turn back on after a power failure, don’t panic. A simple reset might be all you need to restore warmth and comfort to your home. Furnaces may require a manual reset after a power outage or certain system malfunctions, which can prevent them from starting back up automatically.

Not sure how to do that? No worries—Carrier Cooling Center created this step-by-step guide to safely resetting your Carrier furnace. By following these instructions, you can troubleshoot the issue yourself before needing to contact a professional, saving both time and money. 

Step-by-Step Guide to Resetting a Carrier Furnace

After turning off the power to your furnace and letting the system cool down, take the necessary precautions and follow these steps to reset it. 

1. Locate the Reset Button
   The reset button on a Carrier furnace is typically a small, red button located on the furnace’s blower motor. The blower motor is usually found inside the furnace cabinet. To access it:
   Remove the Access Panel: Unscrew or unlatch the front panel of your furnace to expose the internal components.
   Identify the Blower Motor: Look for a cylindrical component with wires connected to it.
   Find the Reset Button: The button is usually on or near the blower motor housing.
   Press and Hold the Reset Button: Press the reset button firmly and hold it for 5 to 10 seconds. This allows the furnace to reset properly.
   
2. Restore Power to the Furnace
   Turn on the furnace’s power switch or flip the circuit breaker to the “On” position. Then, carefully reopen the gas valve.
   
3. Adjust the Thermostat
   Go to your thermostat and set it to a temperature higher than the current room temperature. Ensure the thermostat is set to “Heat” rather than “Cool” or “Off.”
   
4. Monitor the Furnace
   Listen for activation—you should hear the furnace ignite and the blower motor start. Place your hand near a vent to confirm that warm air is flowing. Monitor to ensure it remains running while working to heat to the temperature you set on your thermostat.

Understanding When a Reset Is Necessary

A well-functioning furnace is essential for maintaining a comfortable home environment, especially during the cooler months. Whether you are dealing with a minor malfunction or a full power outage, knowing how to reset your furnace is a handy skill every homeowner should have.

Common reasons to need a furnace reset include:

• Electrical surges or outages can cause the furnace to shut down unexpectedly.
• Safety features may shut off the furnace to prevent damage.
• Error codes or malfunctioning components might require a reset to clear after being fixed.

If your furnace has stopped working and you suspect a simple reset could fix the issue, follow the steps below to safely reset your Carrier furnace. 

Safety Precautions Before Resetting

Safety should always be your top priority when dealing with any heating system. Before you attempt a reset, turn off the furnace’s power and wait several minutes for the system to cool down. If it is a gas furnace, be sure to turn off the gas supply.  

You should also consult the owner’s manual for the specific instructions and safety information related to your Carrier furnace model.

Furnace Troubleshooting Tips

If your furnace does not resume normal operation after a reset, here are other furnace troubleshooting tips:

• Check for Error Codes: Some Carrier furnaces have LED indicators that flash error codes. Refer to your owner’s manual to interpret these codes, and then reset the furnace after addressing the error.
  
• Inspect the Air Filter: A clogged air filter can cause the furnace to overheat and shut down. Replace it if necessary.
  
• Ensure Vents Are Unblocked: Obstructed vents can impede airflow and affect furnace performance.
  
• Verify Thermostat Functionality: Make sure the thermostat is working correctly and has fresh batteries if it’s battery-operated.
  
• Fuel: If your furnace is powered by gas, check with your utility company to see if there is a supply interruption and contact a professional to handle your furnace. If it is an oil furnace, check your fuel supply level to see if it is the cause of your malfunction.
