This PTCR is the PTC start relay for the refrigerator's compressor. It briefly energizes the start winding to get the compressor running, then opens as it warms, supporting reliable starts and helping protect the compressor from repeated restarts.
- Provides initial current to the compressor start winding, then self-limits as temperature rises
- Supports consistent compressor startup to restore and maintain cooling
- Typical failure symptoms: compressor clicks or hums but won't start; refrigerator warm or not cooling
- Visible signs may include discoloration or heat damage at the relay or connector
What's included: 1 PTC start relay
- Disconnect power before servicing; allow sealed-system components to cool
- Note the relay's orientation; firmly seat it on the compressor terminals
- Inspect the overload protector and wiring; replace any heat-damaged components
- If the compressor still won't start, further diagnosis of the compressor, overload, and capacitor is recommended
