Overview

This OEM definite purpose contactor is the switching relay that energizes the compressor and condenser fan circuit on the ICP/Tempstar/Heil RGS183HDAA0AGAA system. When the thermostat calls for cooling, the 24V control coil pulls the contacts closed and routes line voltage to the load. The primary unit (#1171554) is a 2-pole, 30-amp contactor with a 24V coil; the companion 3-pole, 40-amp 24V unit (#1172449) covers higher-load configurations. A failed contactor is one of the most common reasons a unit hums but won't start, chatters, or won't shut off — pitted, welded, or burned contacts and a weak coil are the usual culprits.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
