What Can Cause Your Furnace to Stop Working?

Some issues that can cause your furnace to stop working can be easy to fix, but some can be more complicated and require an expert’s service. In this post, you’ll see some of the problems that can cause your furnace to stop working. We’re also added some troubleshooting tips to make you do a quick fix. Read on to learn about them.

The Circuit Breaker Tripped

A tripped circuit breaker could be the reason why your furnace isn’t working.

Quick Fix: If your furnace stops working, check the circuit breaker to see if it tripped and reset it. If the problem persists, it could be a more serious problem. You’ll need to get an HVAC expert to check it out.

The Thermostat Has Been Tampered With

The thermostat regulates your heating system. If the thermostat is not turned on or is interrupted, the furnace will stop working.

Quick Fix: If your thermostat goes blank, check if it’s turned on or if the thermostat batteries are worn out. Also, check the setting to confirm if it’s on HEAT MODE.

The Furnace is not Well Lubricated

When the furnace is not well lubricated, the bearings within the motor start to friction and make noises. The friction eventually damages the motor and causes the furnace to shut down after some time.

Quick Fix: Turn off the furnace immediately to avoid further damage and get an HVAC technician to check it out.

Clogged and Dirty Air Filter

When the furnace filter is clogged, the furnace overworks itself to meet the desired temperature; this causes the system to overheat and eventually go off.

Quick Fix: Check the air filters to see if it’s clogged. Replace the clogged air filters and turn back the system after some time.

The Igniter is Faulty

When the furnace igniter is faulty, the energy to create heat would not be ignited, which can make the furnace stop working.

Quick Fix: Turn off the furnace, remove the access panel, and check if the igniter is damaged in the form of cracks, fray, or warp. Use a multimeter to check the igniter plug to see if it’s damaged. If the meter reads 0 or infinity, you’ll need to replace the igniter.

The Furnace Control Board is Malfunctioning

This can make your furnace stop working. One of the signs of a malfunctioning control board is getting a rapid uncomfortable temperature.

Quick Fix: Fixing a malfunctioning control board should be done by an expert. You’ll need to get a professional to resolve the issue.
