What Steps Should You Take if Your Furnace Isn’t Turning On?

If your furnace isn’t functioning, it doesn’t necessarily mean you have to get a heating repair expert in San Luis Obispo immediately. A few DIYs can bring your system back into operation.

Things To Do When The Furnace Doesn't Turn On

Here’s how to fix your furnace when it isn’t firing up as it should:

  • Furnace Short-Cycling

If your furnace is on, only to turn off rapidly, you are facing a short cycle issue. It can happen due to airflow issues or the accumulation of grime and dust inside the furnace’s body. Here are some reasons why your furnace is short cycling:

  • Dirty filters can prevent cool air from entering your heater, resulting in a heat build-up within the furnace. It can lead to overheating, and the furnace system will shut down to protect the internal components that make up the unit. Inspect your furnace’s filters regularly and replace them when they look dirty.

  • The sensors in your furnace are designed to detect the flame as gas moves throughout your furnace. If these sensors are dirty due to soot build-up, they might not be able to detect the flame and stop your furnace from operating, requiring heating repair in San Luis Obispo.

  • Check Your Thermostat Settings

The next step in determining if your furnace isn’t turning on is verifying the thermostat settings. Here are some things to examine to make sure your thermostat is operating properly:

  • If your furnace isn’t turning on, you must ensure that the thermostat is in the “ON” position.

  • Since most thermostats use batteries, the batteries may have been exhausted. It is recommended that you change the batteries every year or when required.

  • Ensure the thermostat wiring’s insulation is intact, and call the technician if there are any loose wires.

  • Check Your Circuit Breakers

The most common issue that can lead to problems with furnaces is when the circuit breaker powering the furnace is cut. You can test manually to ensure you have the correct circuits in the “ON” place. If the circuit breakers in your furnace remain in the “ON” position, and your furnace isn’t turning on, you may be experiencing electrical issues that only a skilled technician should fix.

  • Check The Electric Ignition

The electric ignition system may stop working if excessive dirt and soot is accumulated on the ignitor. The entire ignition stops working, and your furnace may not work. The furnace will produce clicking sounds if there is a problem with the electric ignition. Cleaning might help, but you should call professionals to handle it, as these components are delicate.

If your furnace has a pilot light, you can refer to the furnace manual to re-light it again.
