Overview

This is a genuine OEM single-pole definite purpose contactor (Part No. 1173690) for the ICP/Tempstar/Heil WPH3482000RKA1 heat pump. The contactor is the electromechanical switch that energizes the outdoor compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. When the 24V coil is energized, the contactor pulls in and closes the line-voltage contacts to power the unit. Rated at 40 amps with a 24-volt control coil, it handles the inrush and running load of the compressor. Common failure symptoms include a unit that won't start, chattering or buzzing at the outdoor unit, pitted or welded contacts that keep the compressor running continuously, and visible arcing or burn marks on the terminals.

Compatibility

Engineered as the factory replacement for the ICP/Tempstar/Heil WPH3482000RKA1 heat pump condensing unit.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter at the contactor line terminals.
Access — Remove the condensing unit service panel.
Document — Photograph all wire connections before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from the bracket.
Install — Mount the new contactor, reconnect every wire exactly per your photo.
Test — Restore power and confirm the contactor pulls in on a cooling call and that the compressor and fan energize.
