Whirlpool Refrigerator ED20DBXEB01 Won't start or doesn't start

This PTC start relay plugs onto the compressor to momentarily power the start winding and help the compressor spin up smoothly. Replacing a failed relay can stop repetitive clicking and help restore stable cooling performance. What it does:

• Momentarily energizes the compressor's start winding at startup; the PTC element then increases resistance to take the start winding out of the circuit.
• Helps protect against repeated hard-start attempts that cause clicking and no-cool conditions.
• Common failure signs include repeated clicking, the compressor not starting, warm temperatures, burn marks/melted housing, or a relay that rattles when shaken.
• Mounts directly on the compressor terminals and interfaces with the model-specific overload and cover.

• 1 PTC start relay

• Disconnect power and allow components to cool before servicing.
• Access the compressor compartment; remove any cover/retainer to reach the start device.
• Note wiring and orientation; pull the old relay straight off the compressor pins and push the new relay fully onto the pins. Reconnect wires and reinstall the cover.
• Use only the start device specified for your exact model/compressor. If the old relay shows heat damage, inspect the matching overload and wiring for issues.
