Miele Power Supply / Start Load Issue

Refrigerator cycles on and off rapidly or makes clicking sounds; lights dim when compressor tries to start.

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

Weak household circuit or undersized wiring, Failing compressor drawing high current, Defective start relay, Loose power cord or outlet contacts

Safety: Avoid repeated rapid plugging/unplugging; this can damage the compressor.

Steps:

Check outlet and circuit: Ensure the refrigerator is on a dedicated circuit with correct amperage. Avoid using extension cords.
Inspect plug and cord: Look for heat damage or looseness at the plug.
Replace start device: If the compressor attempts to start but fails, a new start relay/PTC may resolve the issue.

If symptoms persist, a failing compressor or internal power supply issue is likely; contact Miele service.
