Fhiaba Compressor Not Starting

Refrigerator and freezer are both warm; compressor is not running, but interior lights work.

Safety Warning

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 compressor start relay or PTC, Open overload protector, Faulty main control board not sending start signal, Internal compressor failure

How to Fix / Troubleshooting

Safety first: Unplug the refrigerator before accessing the compressor compartment. Sealed system work must be done by a licensed technician.

Step 1 – Confirm non-operation:

Listen for any humming or clicking from the compressor area after plugging in; repeated clicks suggest start device issues.

Step 2 – Inspect start components:

Remove the compressor terminal cover and inspect the start relay/PTC and overload for burns or loose connections.
Replace the start device with a compatible Fhiaba part if damaged.

Step 3 – Control board check:

If the start device is good and the compressor still does not attempt to start, the main control board or inverter (if equipped) may be faulty.
Professional diagnosis is required to avoid unnecessary compressor replacement.
