Determining whether your residential refrigerator has a completely ruined and bad compressor involves observing specific sensory, mechanical, and electrical warning signs. First, pull the refrigerator out from the bottom rear and listen closely; a dead compressor remains completely silent or emits a repetitive clicking sound every few minutes as the start relay tries and fails to start the motor. Second, feel the compressor housing; it should feel warm during normal running cycles, not dangerously scorching hot or completely ice cold while interior compartments remain warm. Third, use a digital multimeter set to ohms to test electrical continuity across the compressor terminals. You can troubleshoot power delivery safely. You can verify compressor failure when multimeter resistance tests confirm open motor windings or internal electrical shorts.
