A Simple Guide for Homeowners
If your furnace isn’t turning on or is blowing cold air, it might just need a reset. Understanding how to reset a furnace can save you time and help restore comfort to your home. In this post, we’ll walk you through the steps to reset your furnace, what to look for, and when to call a professional from Liam Services for further assistance.
Understanding Furnace Resetting
A furnace reset is often a simple process that can resolve common issues like a tripped safety switch or a temporary malfunction in your system. However, it’s important to understand why your furnace isn’t working before resetting it. If the issue persists after you reset the system, a deeper issue may be at play.
Steps to Reset Your Furnace
If you are experiencing problems with your furnace and need to know how to reset your furnace, follow these simple steps:
- Turn Off the Furnace: Before starting, turn off your furnace using the thermostat or the power switch located near the unit. Wait for at least 5 minutes to allow the system to cool down.
- Check the Circuit Breaker: Sometimes, a tripped circuit breaker can cause your furnace to stop working. Go to your electrical panel and ensure that the breaker for your furnace is in the “ON” position. If it is off, flip it back on.
- Turn the Furnace Back On: After waiting for a few minutes, turn the furnace back on via the thermostat or power switch.
- Check the Thermostat Settings: Make sure the thermostat is set to the heating mode and set to a temperature that’s higher than the current room temperature. If it’s still not working, check for any error codes on the thermostat.
- Look for an Error Code: Many modern furnaces display error codes on the control panel or thermostat. If you see an error code, consult your furnace manual or call a technician to interpret the code.
If your furnace continues to malfunction after trying to reset it, it’s a good idea to call a professional HVAC technician. Problems like a dirty air filter, malfunctioning limit switch, or pilot light issues can also cause furnace problems.
Common Furnace Issues That Might Need Professional Help
- Furnace Overheating: If your furnace is overheating, it may trigger a limit switch that shuts the system off. You may need a professional to check the furnace’s airflow and ensure the safety systems are functioning correctly.
- Dirty Air Filter: A clogged or dirty air filter can cause airflow problems, leading to overheating and furnace shutdown. If you’ve already reset the furnace and the issue persists, it might be time to replace the air filter.
- Ignition Issues: In some cases, the furnace may not be lighting due to issues with the ignition system. If you’ve reset the furnace and it still won’t ignite, the ignition system may need repair or replacement.

FAQs
Does turning off the furnace reset it?
Turning off your furnace and waiting for a few minutes can help reset it, particularly if the issue is related to a temporary system overload or a tripped limit switch. This allows the system to cool down and restart. However, if the furnace still doesn’t operate after resetting, further inspection may be necessary.
Why won’t my furnace kick back on?
If your furnace isn’t turning on, it could be due to a tripped circuit breaker, dirty air filters, a malfunctioning thermostat, or problems with the ignition system. Start by checking the breaker and adjusting the thermostat. If the furnace still doesn’t respond, it may require professional attention.
How do I force my furnace to start?
To force your furnace to start, try turning it off and back on, ensuring the thermostat is set to heating mode and the temperature is higher than the current room temperature. If this doesn’t work, the issue may lie within the furnace’s components, and a professional diagnosis is needed.
How long does it take for a furnace to reset?
Typically, it takes about 5-10 minutes for a furnace to reset after being turned off. This allows the system to cool down and reset any safety mechanisms. If the furnace continues to have problems after this time, it may require further investigation.
How to tell if a furnace breaker is tripped?
To check if your furnace’s breaker has been tripped, inspect the electrical panel. If the furnace breaker is in the “OFF” position or between “ON” and “OFF,” it’s been tripped. Flip the breaker fully to the “OFF” position and then back to “ON.” If the breaker trips again, there may be an underlying issue that requires professional service.
