Overview
This OEM single-pole definite purpose contactor (part 1173690) is the factory replacement for the ICP / Tempstar / Heil WPG4604130RKB1. The contactor is the heavy-duty relay that switches line voltage to the compressor and condenser fan motor on each cooling cycle. Its 24-volt coil, energized by the thermostat, pulls the 40-amp contacts closed to power the outdoor components. Because the contacts arc every time they open and close, they slowly pit, burn, and can weld shut, while the coil can fail open. Typical symptoms are a unit that hums but won't start, an outdoor unit that won't stop running, audible chattering, or scorched contacts. This higher 40-amp rating suits the larger compressor load on this furnace/condenser combination, and replacing the contactor restores dependable starting.

Compatibility
Built as the correct replacement for the ICP WPG4604130RKB1. ICP equipment ships under the Tempstar, Heil, Comfortmaker, and Arcoaire brands, so this 1-pole 40A contactor with a 24V coil also services equivalent units across those lines that originally used part 1173690. Confirm pole count, amp rating, and coil voltage match your existing contactor.
