Why is My Furnace Not Working

November 22, 2022

Is your furnace not working as the cold continues to invade your home? Haly Home Comfort has 2 simple troubleshooting tips before calling our technicians to get you warm again!


If you’re having furnace problems and you’re wondering why is my furnace not working, then we have two simple furnace troubleshooting tips for you in today’s video.

First, check the thermostat. Look to see if the display is working, or if the batteries need to be charged. Then double-check the system is set to Heat. Finally, is the temperature set to at least three degrees above the current room temperature? Sometimes that’s enough to turn the furnace back on.

If that doesn’t fix your problem, then it’s time to inspect the ignition. Start by checking if there is enough heating oil. If you recently ran out and refilled, some units require you to use the reset button on the burner.

If you have an older system with an always-on pilot light, make sure it’s still on, or re-light the pilot.

When your furnace won’t ignite or stay lit, or if your fuel pump needs to be primed, then it’s time to call a service technician, preferably from Haly Home Comfort. We’re here for all your heating and cooling needs in Chester County, Delaware County, and Montgomery County.
