Furnace Repair 101: Thermostat Issues

Posted on: 11 March 2021

When it comes to furnace problems, most people automatically think of the big stuff, like blower fan failures, pilot light issues, and things like that. However, there's a fairly simple, but common, issue that many people don't even consider until it happens to them and frustration has set in when they can't isolate the source of the problem. Here's a look at what you need to know about thermostat issues and your furnace.

Signs Of Thermostat Problems

The first step to dealing with lesser-known furnace issues is knowing how to recognize them. When it comes to thermostat issues, there are a few common indications. 

For example, one of the most common signs that your thermostat is failing is the rapid cycling of your furnace. If your furnace seems to shut down and turn right back on, only running briefly each time, that's a sign that your thermostat either isn't reading the temperature correctly or it isn't communicating correctly with the furnace. 

Another common indication of thermostat problems is a failure to maintain the programmed temperature. When your furnace is either overheating or underheating your home, it is often because of miscommunication or lack of communication from the thermostat.

Resolutions For Thermostat Problems

If you have determined that your thermostat is a likely cause of your furnace issues, there are a couple of things that you can do yourself to try to resolve the issue. First, make sure that the thermostat is on, set for heat output, and the temperature is set correctly. For thermostats that have batteries, consider changing the batteries to see if this resolves the communication and sensor issues.

For thermostats that are hard-wired into your home's electrical circuit, check that the breaker hasn't tripped. You can try resetting the breaker for both your thermostat and your furnace to see if that resolves the issue.

When you have tried all of these resolution steps with no luck, it's time to reach out to a furnace repair technician. Your furnace repair technician can test the thermostat, check its communication with your furnace, and replace the thermostat if necessary to restore the proper operation. 

These are some of the most common issues that you might encounter when your furnace thermostat is failing, and some of the key steps to resolve those issues. The more you understand about thermostat issues, the easier it is to recognize them and get them resolved right away.
