Your furnace is essential for keeping your home comfortable. When your furnace does not start or stop running, you have repair issues on your hands. You can check and do a few things if your furnace will not start or if it will not turn off before calling in the professionals.
The Furnace Will Not Start
You want to keep your home warm, especially when it is cold outside. Having your furnace not work can be worrisome. Luckily, there are a few things you can do.
First, you are going to want to check your thermostat. Make sure that it is in heating mode. It can be easy for the heating mode to get switched off when you are adjusting the temperature. If heating mode is off, turn it back on and see if that activates your furnace.
Second, you can try turning your thermostat up. Your home may be warmer than it seems, and you may need to turn your thermostat up to get it started.
Third, if that doesn't work, you can turn off the thermostat and the circuit breaker, then take off the cover. Look and see if there are any frayed wires on the thermostat. If there are, that could be your culprit, and you will need a heating specialist to either fix the wires or install a new thermostat.
Fourth, your furnace may not have power. If you have an electric furnace, make sure that the circuit breaker is not tripped or that the power isn't out in your neighborhood. For a gas furnace, make sure the pilot light is ignited.
If none of the above troubleshooting gets your furnace working, you have a bigger issue on your hands that will require some professional intervention.
The Furnace Will Not Stop
Your furnace should not run continuously. If your furnace is constantly running, it will get worn out at an accelerated rate, and the overall efficiency of the unit will be compromised.
You may have your thermostat set too high. If the thermostat is set too high, such as 88 degrees, your furnace will keep running, trying to reach that temperature, even though that is a little warmer than your furnace may be able to heat your home. Just turn your thermostat down and see if that fixes the issue.
Or your furnace may have a clogged air filter, which is depressing the airflow and causing your furnace to run constantly while trying to pull in enough air to heat up your home. Just switch out your air filter for a new one to see if that fixes the issue.
If your furnace either will not stop running or will not turn on, try out some of the suggestions above. If they don't work, then a bigger issue is causing your furnace not to perform right, and you need to bring in a heating repair professional for the repair job.
