There are many common thermostat issues. You may set yours to a certain temperature and then notice, after a while, that the temperature is not as cold or warm as you’d like. Why are you and your family sweating when you set the thermostat to 68 degrees Fahrenheit? The fact is, thermostats can malfunction like everything else. Here are some reasons why:


Dirt can influence how well the thermostat works. If the cooling or heating system won’t shut down or doesn’t achieve the set temperature, the cause may be a build-up of dirt and grime on the components of the thermostat.

Faulty Wiring

Another problem that can cause the thermostat not to work is faulty electrical wiring. If the system isn’t working, check to see if the wires are loose, corroded or sooty. Unless you’re a master electrician, this is really a job for a professional.

Bad Installation

A thermostat that was incorrectly installed might also have problems working. Something that bumps against the thermostat can also cause it to not work well. This is because the thermostat needs to be level on the wall.

Installed in the Wrong Place

A thermostat will have trouble working properly if it is installed near a heat source such as a fireplace or right above a register. It will also have a hard time if it is installed in a place that gets direct sunlight, near a window or near a door that opens to the outside.

Another area the thermostat shouldn’t be installed is over a hole in the wall. The air currents that flow through the hole confuse the thermostat and interfere with its temperature control.


Like every other appliance, thermostats simply wear out when they get too old. If this is the problem with your thermostat, simply call the technicians at Gunthers Heating, Cooling, and Plumbing and have them replace it.
