Hi,

Do the lights come on inside the refrigerator?

Can you hear a clicking sound when the compressor tries to start?

If you hear a clicking sound it could have a bad start relay.

Here is a repair guide to help.

If you don't hear the compressor running or even a clicking noise then it could be stuck in defrost or have a bad cold control.

You could advance the defrost timer by hand or tap on the cold control knob to see if it starts.
