The Common Reasons Your Furnace is Failing: What To Know

Your furnace is one of the most important pieces of equipment in your home, and keeping it in good working order is important. But sometimes, your furnace may start to fail. Here are some of the most common reasons your furnace may be failing:

Clogged or Dirty Filters

One of the most common reasons your furnace may be failing is if the filters are clogged or dirty. Over time, dust, pollen, and other particles can build up on the filters, and this can cause the furnace to stop working. 

 

To fix this problem, you’ll need to take the filters out and clean them with a vacuum cleaner or a hose. Be sure to replace the filters when they’re needed.

Faulty Thermostat or Control Board

If the thermostat or control board is faulty, it may not be able to control the furnace’s temperature properly. This can cause the furnace to stop working altogether. You’ll need to replace the thermostat or control board to fix this problem.

Leaky Hoses

If your hose is leaking, your furnace may not be able to produce the heat that you need. This can cause your home to become too warm, and you may have to turn down the temperature to avoid dangerous levels of heat. 

 

You can use a plunger to push and pull the water out of the hose to fix the leaks. If this doesn’t work, you can use a vacuum cleaner to clean the hose.

Ventilation Issues

If your furnace isn’t properly ventilated, it can also cause it to overheat and eventually fail. Check the vents around your furnace to ensure they’re not blocked by furniture or other objects. If you have a gas furnace, be sure to have it inspected regularly to make sure the venting system is working properly.

The Motor Blows

If the motor on your furnace blows, it can signal that something is wrong with the furnace. The most common problem with the motor is that it’s not getting enough power. 

 

This can be caused by several things, including a dirty air filter, a blocked vent, or a problem with the wiring. You should call a technician to inspect the furnace if the motor blows.

When it comes to dealing with your furnace, you want to be sure that it is working properly. Unfortunately, this is not always the case, and there are a few signs that you should be on the lookout for.
