Bosch Compressor Start Failure

Clicking noise every few minutes, refrigerator not cooling properly

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 start relay or overload, Locked rotor compressor, Low line voltage, Overheating due to dirty coils

Safety first: Unplug the unit before accessing the compressor area.

Steps:

Clean coils: Ensure condenser coils are clean to reduce compressor load.
Check voltage: Avoid using long extension cords. Plug directly into a dedicated outlet.
Inspect start device: Remove the start relay/overload from the compressor and check for burn marks or rattling. Replace with a Bosch-approved part if suspect.

Note: If a new start device does not resolve the issue, the compressor may be locked and require professional replacement.
