What Causes a Furnace to Stop Heating?

Furnaces are very reliable residential heaters. In fact, many homeowners prefer a gas furnace over any other type of heater for a few reasons. Gas furnaces can last 20 years or longer before needing to be replaced and offer reliable heat – even if you lose power during a winter storm. But that doesn’t mean that furnaces are without the potential for problems. In fact, as your furnace ages, it is more likely that it will stop heating. 

If you suspect that something is wrong with your furnace, it may be time for furnace repair in Plano, TX and our team is here to help. Most furnace problems are easy to fix, but occasionally you may need to replace a major component or even your entire furnace. Keep in mind that those major repair expenses usually only happen with older furnaces as they get closer to 20 years old.

Common Reasons for Your Furnace Not Heating

Thermostat Settings

No one wants to make this simple mistake, but it does happen. Sometimes your thermostat simply isn’t set correctly. You may think that your furnace isn’t heating, but in reality your furnace isn’t set correctly to heat. Even if you raise the temperature in an effort to heat your home, nothing will happen. When it comes to furnace problems, this is the best one to have because it’s such an easy fix. 

Tripping a Circuit Breaker

If you try to turn on your furnace and nothing happens, check the circuit breaker that’s connected to your heater. The switch may be tripped and you need to reset it. If this happens once, it’s not a big deal. But if your furnace continues to trip the breaker then you may have a bigger problem. An HVAC expert can investigate the problem and fixer your circuit breaker so your furnace can run without overloading the panel. 

Clogged Air Filter

This is another fairly simple problem to fix if you identify and address it early. When your air filter gets too full of dust and dirt, it blocks airflow into your furnace. This can lead to your furnace working harder to bring in air to heat your home. 

Working harder leaves your furnace at risk for overheating and turning off to prevent too-high temperatures. Changing your air filter is an easy fix. But if your air filter stayed clogged for too long, you may need a furnace maintenance appointment to ensure that it didn’t cause additional damage inside your furnace.

Lack of Lubrication

When your furnace is brand new all of the parts have adequate lubrication to work together smoothly. But over time this lubrication wears off. Dust and dirt can get into your system and reduce lubrication even faster. This leads to parts grinding together and working harder to heat air for your home. A furnace maintenance appointment is a great opportunity for our team to add lubrication to components that work together.
