Common Problems with Furnace Air Handlers

Common Blower Problems

Here are some of the more common problems our technicians see regarding furnace air handlers:

  • Worn/broken belts – it is important that your blower rotate at the rate is was made to in order to maintain proper air flow; the fan belt is a critical part of this process. When the belt becomes loose, wears out or breaks, it needs to be replaced. Wearing belts may make a screeching noise, so if you hear this sound, call for a technician.
  • Problems with fan blades – fan blades can become loose or even break during use. While your fan can still operate with a bent or broken blade, they can cause damage to other parts of your system.
  • Motor issues – your motor can overheat, experience electrical problems or loose lubrication, which can cause the moving parts to grind. Sometimes fan motors can be repaired, but other times replacement may be required.
  • Electrical problems – relays, frayed or corroded wiring or a stuck limit switch can cause electrical problems that affect the operation of the fan and motor. It can be challenging to locate an electrical issue, so it’s best to allow a trained expert to detect the problem and repair it.

If your furnace is turning on but you find yourself without heat or with a serious decrease in the volume of heat coming into your home, you may have an issue with your air handler. It’s always best to have a professional handle any repairs you have. Call ACI Northwest to schedule heating repair service in Spokane today!
