In the midst of cool winter weather, the last thing you need is for your furnace to give you problems. If and when that happens, you’ll need to rely on your furnace troubleshooting expertise until you can get your HVAC technician to take a look at the problem. If you’re not getting enough heat or any heat at all, here are a few furnace troubleshooting tips to consider:
Not getting enough heat?
First, check your thermostat and make sure it’s set to your desired temperature. Also make sure the furnace filter isn’t clogged with debris. An undersized furnace can also fail to produce enough heat for your home’s space.
Not getting any heat at all?
Check the circuit breaker or fuse box for any tripped breakers or blown fuses. Afterwards, make sure your thermostat is set to “heat” and the desired temperature is set above the current indoor temperature. Also make sure your pilot light is on or your electric ignition is working properly.
Blower running continuously?
Have your HVAC technician check and, if necessary, replace the limit switch on the blower motor.
Not getting enough airflow?
Make sure the furnace filter isn’t clogged with debris. Also check the ducts for any breaks, holes or other damage that could accidentally reroute airflow.
Furnace too noisy?
Make sure there aren’t any loose components on your furnace. Some noises, including rumbling or squeaking sounds, could indicate a mechanical problem that your HVAC technician should deal with.
Furnace frequently cycling?
It could be a bad thermostat, clogged furnace filter or poor airflow at play. Oversized furnaces can also cycle frequently, resulting in increased wear and tear.
Can’t see your pilot light?
Try relighting the pilot. If it won’t stay lit, there may be a problem with the thermocouple or the gas supply. Don’t forget to check the surrounding area for drafts.
