Overview

This OEM single-pole 40 amp contactor (part number 1173690) is the primary switching relay for the ICP/Heil/Tempstar WJH348000K000A1 heat pump system. The contactor uses a 24V control coil energized by the thermostat call; when energized it closes its main contacts to deliver line voltage to the compressor and outdoor condenser fan motor. A failing contactor is one of the most common causes of an outdoor unit that will not start, that buzzes without engaging, or that runs continuously because the contacts have welded shut. Pitted, burned, or chattering contacts produce hard starts and premature compressor wear. Replacing the contactor is an inexpensive, high-impact repair that restores reliable starting.

Test - Restore power, place a thermostat call, and confirm the contacts pull in and the compressor/fan start cleanly.
