Reasons Your Payne Heat Pump Is Not Working 

The fan in the heat pump plays an important role. Never turn on a heat pump with a malfunctioning fan. The compressor can get burnt, requiring you a more expensive repair. Moreso, your heat pump could crash.


The fan ventilates the system and lets air pass through every corner to cool down the machine. Also, it keeps it cool when running continuously. The Payne heat pump fan has metal blades and is commonly on top of grid windows, which resembles an electric fan.

Your Payne heat pump fan not working can be due to these reasons:


Due to your Payne heat pump's design, some small debris from outside can get into the unit through the top exhaust or window. Things like twigs, nests, and dust can easily pass through those grids, causing the fan to slow down or get stuck and not spin. Always check regularly to get rid of any debris in your fan.

Sticky Fan Motor

The fan might need a little push to work or spin if there is no debris. Always use a stick, not your hand or fingers, to push the fan blades. Eventually, the motor may give up, so changing it is the best option.

Burnt Motor Or Capacitor

The heat pump capacitor breaks more often than the fan motor and costs less. Check the capacitor with a tester to finally decide on a replacement. 

How To Repair Your Payne Heat Pump

There are several simple ways to repair a faulty Payne heat pump. You'll need to:

Replace Capacitor

You can replace your Payne heat pump capacitor with only a few tools. Follow the ">steps below:

  1. Shut down the power source of the heat pump.
  2. Unscrew different cover panels with a screwdriver until you reach the inner board where the capacitor is.
  3. Discharge the capacitor by tapping the needle nose pliers in each terminal station. Never touch the center or metal part of the tool while discharging.
  4. Unmount the faulty capacitor with a screwdriver.
  5. Take off the wire insulators.
  6. Picture or copy the wire connections before you release the wires with pliers.
  7. Attach the new capacitor by putting the appropriate wire in its terminal.
  8. Re-attach the wire insulators.
  9. Secure the capacitor on the panel with a screwdriver.
  10. Re-install all the different cover panels.
  11. Put on all the connections you detached earlier, including the power cord connector.
  12. Put the outer panel back until you hear the snap or click sound to fit, and turn on the power source.

Replace Fan Motor

Replacing your Payne heat pump fan motor can be a DIY. However, work with caution as the fan blades are dangerous and can cause accidents. Here's the step-by-step guide to changing the fan motor:

  1. Shut down the power source of your heat pump. Make sure no electricity is running in the unit.
  2. Unscrew the round grill or grid covering the fan.
  3. Take off the faulty motor. The size of the old motor should be the same as the new one. So, inspect the installation area for the new motor.
  4. If the connection is solid and tight, cut the wires with a wire cutter.
  5. Picture or copy the fan blade direction to re-install it on the same spot so it will pull out the air and not suck it.
  6. Attach the fan on the new motor with the proper direction of the blades.
  7. A three-wire motor goes to the fan and the power and contractor. A four-wire connection has schematic coloring. The power will get two wires, and the capacitor will get the other two. Check your manual for further instructions.
  8. Re-install the fan motor to its position and screw back the round grill cover.

Other Easy-To-Solve Heat Pump Problems


There are other heat pump issues you could troubleshoot before calling a technician to save money and time. It will also help you to be knowledgeable about your machine. Here is a guide to DIY-repair some common heat pump mishaps:

  • Puffing cold air in a heat setting: Reset your thermostat to heat and set your fan to auto setting.

There are common symptoms to determine if your blower motor is faulty. Knowing the normal function of your whole unit is always advisable to help you distinguish any unusual changes. Here are the symptoms of a defective blower motor:

  • Minimal airflow from the vents. A broken motor produces no airflow at all.
  • Noisy blower motor. Some unusual sounds are vibrating, grinding, and sharp piping noise.
  • Tripping of the circuit breaker. A broken blower motor or capacitor leads to the circuit breaker tripping frequently.
  • Burning smell from the vents. A burning smell means the unit is overheating or, worse, burning up.

Safety Tips

  • Familiarize yourself with your thermostat, which controls your heat pump. 
  • You can leave your fan functioning to lessen any temperature changes. 
  • Inspect your drainage system to check if there's any clogging, especially during the cooling season when the heat pump eliminates indoor humidity. Occasional trickles from the condensate drain are normal.

When Should The Fan Run?

The fan should run on a heat pump when you want to supply air in your house and to help get the desired temperature. The fan and the air handles work together.

Cost Of Replacing A Fan Motor

The fan motor on a heat pump does not often crash or malfunction. However, a worn-out fan motor needs replacement. The cost for fan motor replacement ranges up to $650 or more.

What Temperature Should I Set In The Winter?

The temperature advisable for comfortable living during winter is 68 degrees Fahrenheit. It balances the temperature in your house during fall and winter. The home stays warm, and it's energy-efficient.
