What Can Cause A Furnace To Stop Working?


If your furnace isn’t working, it can be a huge hassle. Not only will you be uncomfortable, but you could also end up with a hefty repair bill.

So what can cause a furnace to stop working?

This article will discuss some of the most common causes. Keep in mind that these are just some of the possibilities. If you’re not sure what’s wrong with your furnace, it’s always best to call in a furnace maintenance professional!

Clogged Air Filter

One of the furnace services technicians provide is cleaning or replacing the furnace’s air filter. A clogged air filter restricts airflow to the furnace. Without the correct air, the furnace may overheat and shut down.

Also, a clogged air filter can cause the furnace to run less efficiently, leading to higher energy bills.

Therefore, having your furnace’s air filter checked and cleaned regularly helps keep it running smoothly.

Thermostat Issues

One of the things that can cause a furnace to stop working is thermostat issues. If a furnace is not calibrated correctly, it may turn off before the desired temperature is reached.

In addition, a faulty thermostat may not accurately reflect the current room temperature, causing the furnace to turn on and off unnecessarily.

A qualified furnace installation & repair technician will be able to diagnose and fix any thermostat issues, ensuring that your furnace runs smoothly all winter long.

Dirty Burners

One of the most common reasons furnaces stop working is the dirty burners.

Over time, dust and debris can build up on the burners, preventing them from igniting correctly. Clogged burners can cause a furnace to overheat, strain the system, and potentially cause a fire.

Keeping the burners clean is essential as part of regular furnace maintenance.

Faulty Igniter

The furnace igniter is responsible for igniting the gas that powers the furnace. If the igniter isn’t working correctly, the furnace won’t be able to start.

In some cases, a faulty furnace igniter can also cause the furnace to shut down unexpectedly.

If you suspect your furnace igniter is faulty, you should contact a qualified furnace installation & repair technician for diagnosis. Ignoring a problem with your furnace igniter can lead to more severe issues, such as a gas leak or a fire.
