What are signs of a failing fridge compressor?

Recognizing the early warning signs that a residential refrigerator compressor is failing and approaching total breakdown can help you prevent spoiled food and emergency replacements. Key indicators include a compressor motor that emits a repetitive clicking sound every few minutes as the start relay tries and fails to engage the motor, a housing that feels dangerously overheated while interior compartments remain warm, interior temperatures fluctuating wildly despite continuous motor running, or tripping your kitchen circuit breaker repeatedly. You can troubleshoot electrical power using a multimeter to check voltage and continuity. You can verify that your compressor is failing when multimeter tests confirm open motor windings, internal electrical shorts, or locked mechanical pistons that prevent the motor from running.
