Refrigerator clicking, compressor won't start (start relay)

The classic pattern is a failed start relay: the compressor can't start, overheats in seconds and the overload clicks off, then retries. Replace the relay first; if it keeps clicking with a good relay, the compressor is suspect (sealed-system work, refer out).

Before you start

  • Unplug the unit (or shut off the breaker) before removing panels or touching wiring.
  • The compressor area can be hot; let it cool.
  • Never open or recharge the sealed refrigerant system: compressor replacement, leaks and refrigerant work go to an EPA 608-certified technician.

How to test a refrigerator bi-metal defrost thermostat

The bi-metal (defrost termination thermostat) is wired in series with the defrost heater. It is closed only when the evaporator is cold and opens once the coil warms during defrost. Testing it at room temperature gives a false "bad" result: it must be cold.

How to test a refrigerator defrost heater

The defrost heater (glass tube, metal sheath or foil type) melts frost off the evaporator a few times a day. A good heater reads in the low tens of ohms; use the wattage math to check the exact value.

How to check an ECM / brushless DC fan motor (what you can test safely)

Many modern refrigerator fans are brushless DC motors with their electronics inside the motor. An ohmmeter cannot judge them reliably. The safe test is to confirm the supply voltage and control/feedback signals at the connector, then swap the motor if the signals are right.
