Steps to Take When Your Furnace Won’t Turn On

You’re not completely hopeless if your furnace doesn’t turn on. There are plenty of minor issues that can cause this furnace problem. You may even be able to fix some of these problems yourself.

Whenever you can’t turn your furnace on, take the following steps.

Check if the Furnace Is Powered On

This step may seem obvious. However, the fact that it is so obvious is often why people tend to forget about it. Also, it can be easy to forget even the simplest things when you’re panicking.

Find the furnace power switch, which should look like a light switch. You can usually find it near the unit on a wall, ceiling, etc. Once you think you’ve found it, flick it on.

Give the furnace a bit of time to start. If that doesn’t work, continue to the next furnace troubleshooting step.

Check if the Thermostat Is Powered On

Your furnace’s thermostat often runs on batteries rather than electrical power. So even if your furnace is on, your thermostat may not be. If the thermostat isn’t on, the furnace may be unable to activate.

Check the thermostat and see if it’s on and/or programmed correctly. If you can’t turn it on, try to give it new batteries. If you can’t turn it on after giving it new batteries, you may need to perform some furnace maintenance and replace the thermostat.

Check if the Air Filter Is Dirty

A clogged air filter can cause your furnace to shut down. Without regular airflow, the heat inside your furnace can increase to dangerous levels. Your furnace may then shut itself down to stay safe.

Check your air filter, which should be on the return vent or at another location. If it seems too dirty, buy a replacement filter and switch it out with the old one. Luckily, you don’t have to be a professional furnace repair technician to perform this action.
