Why Won’t My Furnace Start?

Fall is approaching, and the weather will soon get cooler. After you fire up your furnace, the last thing you want is a home that won’t warm up. Your first question will be, “Why won’t my furnace start?” Well, there are a few reasons why this could be happening. Here are some of the most common causes:

Why Won’t My Furnace Start?

Thermostat settings.

Ensure the thermostat is set to HEAT mode and the temperature is set lower than the current temperature in your home.

Power problems.

Check the circuit breaker to make sure the furnace’s breaker is not tripped. If it is, reset it. Also, make sure the furnace has power by checking the thermostat batteries.

Pilot light. 

If your furnace has a pilot light, make sure it is lit. If it is not, follow the instructions in your owner’s manual to relight it.

Dirty air filter.

 A dirty air filter can restrict airflow and prevent the furnace from working correctly. Check the air filter and replace it if it is dirty.

The unit needs regular service.

If your furnace hasn’t been serviced in a while, it will start having issues. Have your furnace serviced annually by a qualified HVAC technician.

Your system can’t breathe.

Keep the area around your furnace clean and free of debris. Furnaces are often located in storage areas, and can easily have their intake blocked by clutter.
