Blaupunkt Indoor Fan Intermittent Operation

Outdoor unit runs but indoor unit fan stops intermittently, causing uneven cooling.

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

Overheating indoor fan motor, Loose fan connector, Faulty indoor PCB fan driver, Blocked air intake causing motor overload

Safety first: Turn off power before inspection.

Steps:

Clean filters and intake: Ensure unrestricted airflow to reduce motor load.
Check connector: Inspect the fan motor connector on the PCB for looseness or heat damage.
Monitor operation: After cleaning, run the unit and observe if the fan stops after warming up. If so, the motor’s thermal protection may be tripping; replace the motor.
PCB check: If the motor is cool but stops, the PCB driver may be failing and should be replaced.
