Why Is My Heater Constantly Turning Off?

A heater that doesn’t cycle properly is a nuisance. Whether it’s cycling incorrectly or completely turning off, you’ll want to get it fixed right away. Here are a few reasons why it could be acting up.

Damaged Thermostat

Thermostats trigger the operation of your heater. When a thermostat goes bad, it can mess up the heating systems on and off cycle. If the heating system is turning off unexpectedly, it could be a signal that the thermostat is failing or requires fresh batteries. If changing the batteries doesn’t fix the problem, check the location of the device. Thermostats receiving direct sunlight or sitting near a heating vent should be relocated. The extra heat can confuse the sensor and cause the heater to operate incorrectly.

Failing Parts

Regular maintenance can ensure your system stays clean and worn-out parts are replaced before they fail. Sensors, motors, flue pipes, blower wheels, and other components can get dirty and stop working. The team at We Care Plumbing, Heating, Air & Solar in Murrieta can help. We make repairs on all makes and models.

Wrong Size Furnace

If the unit isn’t the right size, it can’t operate normally. Too big, and it shuts off and on too quickly. Too small, and it can only keep a few rooms warm. Contact your installer if it’s a new furnace, and find out about how to correct the problem. Replace an older system with one that’s the right size.

Inadequate Airflow

Dirty filters block the operation of a heating system, and a blocked heater can overheat and turn off. Change the filter every month to ensure the system doesn’t get clogged or backed up. Replacing air filters monthly is an inexpensive way to make sure your system runs smoothly.
