Overview

This OEM 2-pole definite purpose contactor (part #1171554) is the switching relay that powers the compressor and condenser fan in your ICP/Tempstar/Heil RGS243SEEA0AAAA system. Rated for 30 amps per pole with a 24V control coil, the contactor energizes when the thermostat calls for cooling, closing both line-voltage poles to start the outdoor unit. Over time the contact points pit, arc, and weld from the high inrush current of every compressor start. A failing contactor is one of the most common no-cool service calls: symptoms include a buzzing or chattering outdoor unit, contacts that stick closed and won't shut off, or contacts that fail to pull in at all. Replacing it is inexpensive insurance against a far more costly compressor failure.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?
