While some heating problems take a while to recognize, you’ll notice an inoperable blower fan right away.
Once the furnace’s fan stops working, the system won’t be able to push heated air into your living spaces. This can result in the furnace overheating and other noticeable signs of the problem. Use this guide to explore the types of furnace repair your system might need.
The Circuit Breaker Needs Resetting
Many common furnace repair problems result from electrical issues. Since most home heating options use electricity in some way, this is an issue that should concern every homeowner. If you notice that your blower fan isn’t working, try resetting the breakers. If that doesn’t help, your HVAC technician might check the wiring to find electrical faults.
How Can I Tell if My Furnace Has an Electrical Short?
You can tell that an electrical short is interrupting the operation of your furnace fan by looking for burnt wiring. The furnace might also trip the breakers repeatedly.
If you have a newer furnace, the diagnostic light will tell you something is wrong. The light flashes a code that your HVAC technician will recognize and use to diagnose the specific malfunction.
The Drive Belt Is Worn or Cracked
It’s easy to forget that a drive belt connects the blower motor to the fan, but a faulty belt can affect your ability to lower heating costs in your home. Over time, the belt will become worn due to friction and stress. It might become loose, or the belt could crack or break.
While you’ll need furnace repair to replace a damaged belt, you can prevent this problem with annual maintenance. During the furnace tune-up, your HVAC technician will check the belt. If it looks worn or damaged, they will replace it as part of the maintenance service.
The Blower Motor Is Malfunctioning
As a part of your HVAC maintenance plan, the technician will lubricate and fine-tune the motor. Over time, consistent usage can cause that lubrication to deteriorate, and the resulting increased friction will damage the motor. You might need furnace repairs or a full motor replacement if the unit no longer functions properly.
How Often Does a Blower Motor Need Lubrication?
You can reduce the need for heater repair by keeping up with furnace maintenance. While newer furnaces come with motors that have permanent lubrication, older models have oil ports for manual lubrication. Your HVAC technician will add lubrication during the annual tune-up. Adding lubrication once per year is usually sufficient.
You can usually tell that the motor needs additional lubrication by listening for unusual sounds. Squeaking noises or the sound of metal grinding on metal indicate the need to top off the lubrication. Read the furnace owner’s manual to find out which type of oil to use for lubrication.
