However, just like all other equipment, your gas furnace can also come across one or two malfunctions and service issues throughout its lifespan. You can expect more of it if your gas furnace is poorly maintained. If you encounter some noticeable signs of gas furnace issue, don’t hesitate to call a professional. Here are the most common furnace repairs that you might need.
- Cracked Heat Exchanger Replacement. The heating part of the furnace happens in the heat exchanger. It’s a metal chamber containing the hot combustion gas from the burners which is then used to warm your home. Too much strain on the heat exchanger however can cause it to crack, giving way for the combustion gas to flow out of the system. An indication of a cracked heat exchanger is the clicking sound when the blower shuts off.
- Blower Electrical Repairs. Sometimes, relay problems happen in the motor part of the gas furnace. It’s when you turned on your furnace and caused a circuit breaker to trip, which happens over and over again. This is an indication of a failing motor, relay issue or the gas furnace requires some electrical power.
- Failed Electronic Ignition Replacement. Older gas furnace units are using pilot lights to ignite their burners but newer models have an electronic igniter which is more reliable and energy-efficient. This uses a spark to get the burners going but the electronic ignition system can also fail causing your furnace not to light. This is when you need to replace the broken igniter.
- Cleaning The Burners. In order for the burner to light, it needs a supply of oxygen. However, if it is covered with dust, rust flakes and other particles, it will be hard for the burner to access the oxygen. This can cause delay to the system’s operation. You may need to have a professional technician clean your burners. This is a complicated job so you should not try to do this yourself.
