When your furnace stops working in the middle of a frigid Minnesota winter, it’s easy to panic. Before you call, you can do some quick checks yourself. These might even help get the heat back on or help explain things better to a technician if you do need professional help.
Here’s what you can do when your furnace suddenly stops delivering heat:
- Check your thermostat
Make sure it’s set to “heat,” that the temperature is set above the current room temp, and the batteries aren’t dead. - Look at the air filter
A dirty air filter can restrict airflow enough to trigger a safety shutoff. If it’s dirty, replace it, and see if the system restarts. - Inspect the circuit breaker and power switch
Furnaces have their own power switch, often near the unit. You can also check the electrical panel for a tripped breaker; a simple power issue can look like a bigger problem. - Clear snow and ice from outdoor vents
Blocked intake or exhaust pipes can shut your furnace down for safety reasons. Carefully clear any visible buildup outside. - Pay attention to warning signs
Listen for unusual sounds, note any strange smells, and look for error codes on the furnace display. That info can be a big help to your technician.
