4 Things To Check When Your Furnace Stops Working

It’s easy to panic when it’s cold outside and your furnace suddenly stops blowing warm air, or even stops blowing any air at all.

Of course, we’re always here for you when you need us, but there are a few things you can check yourself that might just get your furnace running again without having to call for furnace repair service.

#1 Check The Breaker In Your Electrical Panel

The picture to the right shows what a breaker looks like when it’s tripped, but sometimes it won’t be quite so obvious. Find the furnace breaker, and turn it to the Off position and then flip it back to the On position.

#2 Check The Furnace Disconnect Switch

There should be a switch near your furnace that looks like a light switch. Sometimes the switch will be black instead of white. Make sure it is in the On position.

#3 Check The Air Filter

If you haven’t changed the air filter in your furnace lately, now would be a good time to do that. Once your air filter gets dirty it’s going to start restricting the air flow through your system. This can cause the furnace to start tripping the high limit switch, which shuts the furnace down as a safety precaution.

#4 Check The Batteries In Your Thermostat

If your thermostat has batteries and you haven’t replaced them recently, go ahead and replace them now. Old batteries are often the culprit when your furnace stops working and you’ve checked the other three things on this list.
