How to Fix / Troubleshooting

Safety: Disconnect power before accessing the blower assembly.

Steps:

Check for obstructions: Remove the front cover and ensure nothing is blocking the blower wheel.
Spin test: Try spinning the blower wheel by hand. If it is stuck, remove debris or adjust its position.
Inspect wiring: Verify the fan motor connector is fully seated on the control board and that wires are not damaged.
Motor replacement: If the motor hums but does not turn, or does nothing at all with proper voltage present, replace the indoor fan motor.
Board issue: If a new motor does not run and there is no output from the board, the control board may need replacement.
