ICP 2-Pole 30A Contactor 24V Coil for RGS090SFBA0AGAA — OEM 1178074 | Ships Today

Overview

This genuine ICP OEM definite-purpose contactor (part 1178074) is a 2-pole, 30 amp unit with a 24-volt control coil. The contactor is the electrically controlled switch that energizes the compressor and condenser fan when the thermostat calls for cooling. When the 24V coil pulls in, the contacts close and pass line voltage to the load; when the call ends, the coil releases and the contacts open. Over time the contacts pit, arc, and weld from repeated switching, and the coil can fail open — leading to a system that won't start, chatters, or won't shut off. A new OEM contactor restores clean, reliable switching.

Specifications

Compatibility

Fits the ICP RGS090SFBA0AGAA and many Heil, Tempstar, and Comfortmaker condensing units calling for a 2-pole, 30A, 24V-coil contactor. Match poles, amp rating, and coil voltage to your existing unit before installing.

Installation Guide

1. Safety First — Disconnect power at the unit disconnect and breaker, then verify zero voltage with a multimeter across all line terminals.
2. Access — Remove the electrical access panel on the condensing unit.
3. Document — Photograph every wire and terminal position before disconnecting.
4. Remove — Transfer wires one at a time from the old contactor to the new one, or label them, then unbolt the old contactor.
5. Install — Mount the new contactor, reconnect line, load, and 24V coil leads per your photo, and confirm tight terminals.
6. Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with no chatter.
