Overview
This is a genuine OEM single-pole definite purpose contactor (Part No. 1172472) for the ICP/Tempstar/Heil model WPG4244040LKA1. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. Rated at 30 amps with a 24-volt control coil and equipped with an integrated shunt, it carries the high-voltage load to the compressor while the low-voltage coil pulls the contacts closed. Common failure symptoms include a system that hums but won't start, chattering or buzzing at the contactor, pitted or welded contacts that won't release, and a compressor that runs continuously because the contacts have fused shut. A worn contactor is one of the most frequent causes of no-cool service calls.
