Reasons Why Your Heater Won’t Turn Off

Heater Troubleshooting in Burbank, CA

It is concerning when your heater isn’t operating as it should. One sign there’s a problem is that it won’t turn off even when your desired temperature is reached. There are a few common problems that cause this. Here are some possible explanations for why it occurs.

Dirty Air Filter

When your air filter gets too dirty, it can actually impede the flow of air. This forces your furnace to run constantly as it tries to reach your desired temperature. Inspect the air filter. If it’s dirty, either clean it if it’s washable or replace it if it’s disposable. The problem should clear up within an hour.

Thermostat Problem

It may be just the blower that is running constantly and not the heater. Make sure the thermostat is set to “AUTO” and not “ON.” Also, make sure the temperature isn’t set too high.

Your thermostat may be broken and need to be repaired or replaced. One sign of this is that the display is nonresponsive. You should have an HVAC technician determine the problem.

Certified Service in Burbank, CA, can help you with a broken thermostat. If it needs to be replaced, we have several programmable and smart thermostats to choose from.

Broken Blower Fan Motor

A malfunction in a blower fan motor can cause it to run constantly. It’s often the fan limit switch that is broken. This component tells your furnace to turn on and off. An HVAC technician can solve this problem for you.

Leaky Ductwork

There are two types of ducts in your home, the supply and return. If the supply ducts are leaky, warm air is escaping before it ever reaches the inside of your home. Your furnace will run constantly because your home never reaches your desired temperature.
