Furnace Problems: 10 Common Issues & Easy Solutions

The most devastating problem that a homeowner can face is a malfunctioning furnace. When your furnace stops working, you should have it repaired as soon as possible. So among the 10 most common furnace problems, which are you most likely to encounter?

 

  • The Thermostat is Not Working.

For a furnace to function properly, the thermostat is one of the most crucial components. Ineffective fans could be the cause of a malfunctioning thermostat. You will experience inefficiency in your furnaces due to the thermostat’s battery running.

 

Solution: check the settings to see if the fan is on automatic and constantly running at all heating settings. Contact a professional for furnace repair in Louisville, KY, if the problem can’t be fixed by yourself

 

  • Filters Clogged with Dirt and Debris

A dirty o’clock filter can reduce the intake your furnace needs to operate, reducing its efficiency. 

 

Solution: To ensure optimal performance, make sure your filters are cleaned every four months

 

  • Wrong Color of the Pilot Light

When it is working properly, the pilot light should always be blue. Any other color than blue indicates an excessive amount of carbon monoxide in your gas furnace.

 

Solution: It is dangerous to ignore any change in the pilot light color. Seek professional help for furnace repair in Louisville, KY, immediately.

 

  • The Heat Exchanger is Cracked.

Cracked heat exchangers can be costly and troublesome. For your furnace to operate safely, the working flame must be separated from the air, so if the heat exchanger is not functioning when it should, your house can’t maintain the desired airflow.

 

Solution: Consult a professional for heating repair in Louisville, KY, as soon as possible

 

  • Malfunctioning of the Blower Belt

As a result of the blower belt, the furnace fan keeps running smoothly. In some instances, it will break and squeal loudly.

 

Solution: If you hear the belt squealing, replace it to improve the furnace’s efficiency. Call a professional for furnace replacement in Louisville, KY

 

  • Over Cycling

The filters have to be replaced when they are clogged, there is an improper airflow, or the thermostat is set too high or too low. These factors result in higher electricity bills. 

 

Solution: Get it resolved by calling a professional.

 

  • Misaligned Limit Switch

A malfunctioning limit switch may cause your furnace to blow even when it should not continuously.

 

Solution: Professional help is all that is required for repairs

 

  • Not Enough Air

The blower may be clogged, or the filters are dirty when the furnace is not blowing enough air. Check your blower to see if it has a flashing red light.

 

Solution: If you experience any of these problems, do not hesitate to call a professional.

 

  • Worn Out Ball Bearing

Furnace motors require ball-bearings to function properly. The cracking sound is caused by these components wearing out over time and needing replacement.

 

Solution: Turn off the appliance immediately if you hear such noises, and contact a repair expert.

 

  • Unusual Noises in a Furnace

Generally, furnaces don’t make strange or unusual noises. It’s time to have it checked if you hear rattling, popping, or pining noises.

 

Solution:  If you experience any of these problems, do not hesitate to call a professional.
