Furnace Problems? It Could Be Your Thermostat

It's never a good feeling when your furnace won't turn on in the winter. It's also not good when your furnace runs but won't keep your house warm enough. A furnace can stop working properly for many reasons, but one reason is one that people don't often consider – their thermostat.

A thermostat controls your furnace and can prevent it from working correctly. Thermostats can experience several problems that cause issues with a furnace running. Here is a guide to help you learn more about this particular furnace problem that you might encounter.

The functions of a thermostat

You probably realize what your thermostat does, but you might take its functions for granted until it stops working. The thermostat is a device connected to your heating system, and it tells your system to turn on and off based on the temperature you choose. For example, if it's cold in your house, you turn the temperature up to turn the heat to a warmer temperature. Your furnace knows this and runs longer to heat your home. If it's hot in your house, you can turn the thermostat down. If the thermostat isn't working properly, it disrupts this process.

The wiring might be bad

One problem you might encounter is bad wiring. Wiring tends to last a long time, but it doesn't last forever. Additionally, wiring can come loose, or rodents might chew it up. If something happens that damages the wiring, it disconnects the thermostat from the furnace. As a result, the furnace doesn't work properly. In fact, the furnace might not even turn on if the wiring is bad. A heating repair company can fix the wiring if this is the issue.

The thermostat might be shot

The other problem you might have is a bad thermostat. A thermostat can wear out over time. It can also experience issues with the calibration. If either of these problems occurs, your thermostat can't order the furnace to turn on and off properly. If this is the problem, a heating repair company must replace the thermostat with a new one.

You need heating repairs if you have thermostat problems

When you have furnace problems, they might be the result of a furnace issue or a thermostat problem. You will need to hire a heating repair company to determine the cause of the problem and make necessary repairs. Do you currently need repairs?
