Reasons Why Your Heater Keeps Shutting Down

Nothing can be more frustrating than having your heating system start and stop. Not only does this compromise your indoor comfort, it can cause more problems to develop with your system as it continually turns on and off. There can be a few reasons why your heating system won’t stay on, but determining the cause should always be left to an expert. If you are having problems with your heating system, call the people you can count on for repair: At Your Service Plumbing, Heating & Air.

Why Is My Heater Shutting Down?

Here are some of the reasons why your heating system is starting but not staying on:

Thermostat Problems

Your thermostat is the control center for your heating system, so if something is wrong with it, you will most likely have problems with your heating system. Older thermostats needs to be calibrated correctly in order to read the air temperature correctly; if the calibration is off, the thermostat my read the air temperature incorrectly and turn your heating off prematurely. Another common problem that can develop with your thermostat is problems with the wiring. The wires in the thermostat can corrode and fray, which can interfere with the correct operation of the thermostat.

Dirty Air Filter

The air filter in furnaces and heat pump systems should be changed every 3 months; otherwise, the air filter can become clogged and restrict air flow. If the air flow is restricted enough, the system may not be able to run as it should.

Problems with Safety Mechanisms

Your heating system has a number of safety controls on it to help ensure the safe operation of the system. Sometimes these safety mechanisms can malfunction, and when they do, they can turn off your system. For example, furnaces have a component called a limit switch. This switch activates the blower when the warmed air from the heat exchanger has reached the correct temperature; however, this switch also acts as a safety device and kills the burner when the heat exchanger becomes too hot. If the limit switch is malfunctioning, it may turn the burner off even when nothing is wrong.
