ICP 2-Pole 30A Contactor for RGS240SSAA0AAAA — OEM 1171554 24V Coil | Ships Today

Overview

This is the genuine OEM definite-purpose contactor (ICP part number 1171554) for the ICP/Tempstar/Heil RGS240SSAA0AAAA system. This is a 2-pole contactor rated for 30 amps with a 24-volt control coil. The contactor is the high-voltage switch that energizes the compressor and condenser fan whenever the 24V control signal calls for it. Over thousands of cycles the contact points pit, burn, and weld, while the coil can lose its magnetic pull — leading to chattering, a system that won't start, or contacts that stick closed and won't shut off. Replacing a worn contactor restores reliable switching and protects the compressor from damaging electrical conditions.
