Whirlpool split air conditioner shows H6 and the indoor fan does not run or runs erratically.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed DC indoor fan motor, damaged Hall sensor inside motor, wiring harness fault, defective indoor PCB

Safety: Turn off power at the breaker before opening the indoor unit.

Steps:

Remove the front cover and filters to access the blower and motor.
Check for obstructions and verify the blower wheel spins freely.
Inspect the motor wiring harness and connector for damage or loose pins.
If the motor receives power but does not start, the DC motor assembly is likely defective and should be replaced as a unit.

Because DC fan motors and PCBs are expensive and require correct diagnosis, professional service is recommended for H6 faults.
