The Heat Pump Blower Is Not Blowing


A heat pump is a device installed on the outside of your home that moves heat from one location to another, raising its temperature along the way. Heat pumps use a blower fan to move the air in or out of the home, removing impurities in the process. When the heat pump isn't transferring air properly, there may be a series of different problems effecting the mechanical process. Proper troubleshooting will lead you to the source of the problem and help you decide whether you can repair the unit yourself, or whether you need professional assistance.

Things You'll Need

  • Fuse puller
  • Filter
  • Vacuum
  • Oil
  • Check the fuse box of your home and turn the fuse for the heat pump to the "On" position. If it shuts off immediately, there's a short somewhere in the electrical system. Remove the fuse with a fuse puller. Use the numbers on the side to find the correct fuse replacement, and replace the fuse. There's a problem with the electrical load somewhere in the heat pump if the fuse continues to flip to the off position. Contact a service professional.

  • Turn the thermostat to a higher heat to see if the blower starts working.

  • Turn the power to the unit off. Press in the access panel button to open the access panel on the heat pump controls on the inside of the home. Pull out the filter and replace it if it's dirty.

  • Clean the coils of the heat pump using a vacuum with a soft brush attachment.

  • Turn off the power to the unit and locate the blower motor on your unit. Turn the blower motor by hand. If it doesn't move, oil the blower oil ports. Reference your owner's manual for the correct oiling procedure. Turn on the unit. Call a professional if the motor doesn't move.
