5 Tips If Your Furnace Stops Working

When the temperature drops and your furnace suddenly stops working, here are a few quick things you can check before calling for service:

1️⃣ Check your thermostat.
Make sure it’s set to “Heat” and the batteries aren’t dead. A simple reset can sometimes bring your system back to life.

2️⃣ Inspect your air filter.
A clogged filter can restrict airflow and cause your furnace to shut down for safety reasons. Replace if it looks dirty.

3️⃣ Verify the power source.
Check the furnace switch, breaker, or fuse. If it tripped, reset it once and see if the system restarts.

4️⃣ Look at your furnace door and safety switch.
Many systems won’t run if the panel isn’t securely closed. Ensure it’s latched properly.

5️⃣ Listen and observe.
If you hear unusual noises, smell gas, or notice burning odors, turn the system off and wait for a professional to inspect it.
