Help! My Furnace Is Not Turning On!

Help! My Furnace Is Not Turning On!

No matter how much we hate to experience a malfunctioning furnace in the cold months, we cannot prevent it from taking place, especially for poorly maintained units. When it fails to turn on, you can do some simple check-ups to save money and time. Be sure to inspect the crucial components first before opting for a repair.

See if fixing any of these things can make your furnace run. If not, it is time to call the pro:

  • Power Supply

Issues with the power supply will definitely prevent your furnace from turning on. Check if there are tripped breakers or if the unit is disconnected from the power source. It is also helpful to check the electrical panel for issues and reset it if necessary. Then, set the power switch of your furnace to “ON.”

  • Thermostat

The thermostat plays a crucial role in the operation of your furnace. If your unit fails to turn on, you can blame your malfunctioning thermostat for that. Be sure to switch it to heat and set it above the room’s current temperature. Sometimes, dirty components and loose calibration also cause it to fail. If it is a power supply issue, changing the batteries will do the trick.

  • Pilot Light

Check if the pilot light of your furnace (if there is) fires up. A faulty or dirty sensor prevents the pilot light from operating. This, however, requires professional inspection. If you doubt it’s a serious case, you can check the error code of your furnace against the user manual. If you are not comfortable doing these checks, you can always get an HVAC expert to help you.

  • Furnace Filter

A clogged furnace filter is a nightmare to your furnace. It can impede airflow and give your unit a hard time providing sufficient heat for your home. Always check your filters and replace or clean them if necessary. Manufacturers require you to do it at least every 1-3 months.

  • Gas Supply

The gas supply of your furnace should be open and free from any disruptions. The furnace will not run without fuel, so you should check the gas supply from time to time.

These are only simple inspections that even professionals recommend you check yourself when your furnace is not turning on.
