Bosch Outdoor Fan Motor Failure Without Code

Unit runs in cooling but the outdoor fan does not start; indoor unit may show no error.

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 outdoor fan motor, Faulty fan capacitor (on non-DC models), Stuck fan blade, Loose fan motor connector

Safety first: Turn off power before touching the outdoor fan.

Steps:

Check for obstructions: Ensure nothing is blocking the fan blade.
Spin test: With power off, gently spin the fan blade by hand. It should rotate freely. Stiff movement indicates bad bearings.
Inspect wiring: Check that the fan motor connector is firmly plugged into the outdoor PCB.

Resolution: Replace the outdoor fan motor (and capacitor if used) with the correct Bosch part. This is typically a technician job.
