Supco 12555902 Relay Overload Whirlpool Refrigerators

Product Description

The SUPCO 12555902 is a relay overload start device designed to replace worn or damaged original-equipment components in Whirlpool-brand refrigerators and freezers. The relay overload assembly works in tandem with the compressor, providing the starting current needed to bring the compressor motor up to operating speed and then protecting it from overload conditions during normal run cycles. This part is installed by appliance technicians and HVAC-R service professionals performing compressor circuit repairs. Matching the manufacturer part number to the unit before installation is required to confirm proper fitment.

This relay overload is intended for use in household refrigerators and freezers manufactured under the Whirlpool brand. It is a direct OEM-style replacement suited for compressor service calls where the existing start device has failed, causing the compressor not to start or to cycle off on overload. Compatible manufacturer model numbers include 12555902-REPL, 22 M058, 5SP04M419PF, and 8170706. Always verify the model number on the unit data plate before ordering.

Installation Notes

Installation should be performed by a qualified appliance or HVAC-R technician. Disconnect power to the refrigerator or freezer completely before accessing the compressor compartment or removing the existing relay overload. The relay overload connects directly to the compressor start terminal and must be seated securely to ensure proper electrical contact. Do not operate the unit without the overload in place, as compressor damage may result.
