Safety first: Unplug the unit. Beware of sharp metal edges and fan blades.

Steps:

1. Inspect fan area: Remove the cover and check for debris, insulation, or wiring contacting the fan blade. Clear any obstructions.
2. Check fan blade: Ensure the blade is firmly attached to the motor shaft and not cracked or warped.
3. Test motor rotation: Spin the fan blade by hand. It should turn freely. If it is stiff or seized, the motor bearings may be failed.
4. Verify power to motor: With caution and the unit plugged in, start a dehumidify cycle and check if the motor receives voltage (this step is best done by a technician). If voltage is present but the motor does not run, replace the motor.
5. Replace fan motor: Install the correct Carrier fan motor assembly, transferring the blade and any mounting brackets as originally installed.
6. Control board check: If the motor is good but never receives power, the fan control circuit on the main board may be defective.

Dehumidifier shows F2 and the fan may not run or runs erratically.
