Overview

This is a genuine OEM 2-pole definite purpose contactor (part #1178074) for the ICP/Tempstar/Heil RGS101STAA0AAAA furnace and matched cooling system. The contactor is an electrically operated switch: when the thermostat calls for cooling or blower operation, a 24V signal energizes the coil, pulling the contacts closed to deliver line voltage to the compressor and condenser fan motor. Rated for 30 amps across two poles with a 24V control coil, it is built for the constant make-and-break duty cycle of HVAC switching. Common failure symptoms include pitted or welded contacts, a buzzing or chattering coil, a system that will not start, or a unit that runs continuously because the contacts have fused shut.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?
