3 Tips for Troubleshooting Why Your Furnace Won’t Shut Off

When your furnace is having trouble shutting off, it’s either continuously running beyond the settings or failing to ever reach the set temperature. Sometimes, the solution is an easy fix you can do yourself. Other scenarios require a certified technician.

1. Check the Thermostat’s Set Temperature

The first thing to do when a furnace won’t shut off is to compare the thermostat’s current temperature to the set temperature. A temperature set too high may cause too much demand on the heating system. Keep the temperature set at a reasonable level.

2. Check the Air Temperature

Place your hand under the air blowing out of the vent to check if it’s hot or cold. If the air is cold, something may be wrong with the blower motor. Look at the thermostat to see if it’s in “on” or “auto” mode. If it’s in the on mode, switch it to auto and wait a few minutes to see if that solves your problem. The blower motor is responsible for circulating air over the heat exchanger. When something is wrong with the blower motor, you’ll need a professional to fix it.

3. Check the Electrical Wiring Inside the Thermostat

If you know how to, detach your thermostat from the wall and open it to check the wired connections. Any loose connections could be the reason behind your furnace continuously running past the set temperature. You can also ensure that it’s wired correctly by comparing the wiring with the diagram in your thermostat’s manual. You can try fixing the wiring yourself, but most people prefer to let a heating company handle that task. Take a picture of the wiring before attempting to rewire it in case you want to revert.
