Whirlpool W10873803 Refrigerator Start Device

Product Description

The WHIRLPOOL W10873803 is a refrigerator start device designed to initiate compressor operation in domestic refrigeration units. At startup, the compressor motor requires a brief surge of current to overcome initial resistance; the start device provides that electrical kick and then drops out of the circuit once the compressor reaches operating speed. This part is a direct OEM-style replacement component installed by appliance technicians and experienced service pros. Its compact footprint measures 1.75 x 1.25 x 2.75 inches, making it a simple plug-in swap in the compressor compartment.

This start device is used in residential refrigerators where the compressor relies on a positive temperature coefficient (PTC) or relay-style start assist component. It is typically located at the rear lower section of the unit, plugged directly onto the compressor terminals. Service technicians replace this part when a refrigerator fails to cool, the compressor clicks on and off repeatedly, or the compressor does not start at all despite the thermostat calling for cooling.

Installation Notes

The start device connects directly to the compressor start pin and should be handled carefully to avoid cracking the housing. Do not apply lubricants or sealants to the terminal connection.
