Overview

This is the OEM definite-purpose contactor for the ICP / Tempstar / Heil WPG3604130RKC1 packaged unit, part 1173690 — a single-pole, 40-amp contactor with a 24V coil. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed to pass line voltage to the load. Over time the contacts pit, burn, or weld, and the coil can fail open, causing the unit to chatter, fail to start, or stay running. A fresh OEM contactor restores clean, reliable switching and protects downstream components.
