Compressors & Relays

Refrigerator Compressor Start Relays and Overloads

The start relay gives the compressor the boost it needs to start, and the overload protects it from overheating. A failed relay is a common and inexpensive cause of a refrigerator that clicks but does not cool.

Signs of a Bad Start Relay

  • Clicking sound from the back every few minutes
  • Compressor hums but does not run
  • Refrigerator and freezer both warm
  • Rattle when you shake the relay

Popular Replacements

  • GE WR07X26748, WR07X26749 and WR08X22874

Match the relay part number and your refrigerator model number. Unplug the unit before servicing.
