The compressor start relay is the component that gives the compressor its initial electrical kick to start each cooling cycle. When the relay fails — whether it rattles, burns open, or simply stops making contact — the compressor can’t start, the refrigerant stops circulating, and the entire fridge warms up within hours. The 5304491583 Refrigerator Compressor Start Relay Controller Kit replaces the failed relay assembly with a direct OEM fit, restoring compressor start function and full cooling in a single straightforward repair.
⚠️ Symptoms of a Failed Compressor Start Relay
- Refrigerator runs (fan and lights work) but interior is warm and not cooling
- Clicking or chattering sound from the back of the fridge every few minutes as the compressor tries to start
- Compressor hums briefly then shuts off without completing a cooling cycle
- Rattling sound from the relay when removed and shaken (burned or broken internal contact)
- Freezer section loses temperature while fridge section warms up
- Fridge cycles on and off rapidly without maintaining set temperature

A failed start relay and a failed compressor produce identical symptoms — a fridge that runs but won’t cool. Before quoting a compressor replacement, remove the relay from the compressor start pins and shake it. If it rattles, it’s failed. A $150 relay fix beats a $600+ compressor replacement every time, and this is the first part to test on any Frigidaire or Electrolux no-cool call.
⚙️ Installation Notes
- Skill Level: Beginner to Intermediate — rear access panel removal required
- Always unplug the refrigerator before beginning any repair
- Pull the fridge away from the wall and remove the rear lower access panel to expose the compressor
- The start relay plugs directly onto the compressor start pins — pull straight off, no tools required
- Shake the old relay — a rattle confirms failure; a silent relay should still be tested for continuity
- Press the new relay firmly onto the compressor pins until it seats, reinstall the panel, plug in, and allow 24 hours for the fridge to reach set temperature
