Overview

This genuine OEM 2-pole, 30-amp contactor (part number 1178074, "CONTACTOR 2P 30A 24V") for the ICP/Tempstar/Heil RGS150LRCA0AAAA is the electromechanical switch that energizes the high-voltage components when the 24V control circuit calls. When the thermostat sends a 24-volt signal, the coil pulls the contacts closed and passes line voltage to the load; when the call ends, the contacts open. Contactors fail from pitted, burned, or welded contacts and from worn coils that hum, chatter, or refuse to pull in. A failed contactor is one of the most common causes of a system that won't start, short-cycles, or runs continuously.

Is this contactor compatible with Bryant or Payne too?
