ICP 2-Pole 30A 24V Contactor for RGS303SEFA0AAAA — OEM Definite Purpose | Ships Today

Overview

This genuine OEM 2-pole definite purpose contactor, part number 1171554, is rated 30 amps with a 24-volt control coil. A contactor is the high-current switch that closes the line voltage circuit to the compressor and condenser fan when the 24V control signal energizes its coil. Over time the contacts wear, pit, and burn from the arcing that occurs every cycle. A failed contactor is one of the most common no-cool service calls — symptoms include a system that hums but won't start, contacts welded closed (unit runs nonstop), chattering, or no response to a cooling call at all. Replacing the contactor at the first sign of pitting prevents motor and compressor damage.

Specifications

Compatibility

Direct OEM fit for ICP-family model RGS303SEFA0AAAA and other Tempstar, Heil, and Comfortmaker systems using part 1171554. Confirm 2-pole, 30A, 24V coil specs against your existing contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker; verify zero voltage with a multimeter.
2. Access — Remove the service panel to reach the contactor.
3. Document — Photograph all line, load, and coil wiring before disconnecting.
4. Remove — Transfer wires one at a time, then unscrew the old contactor from its bracket.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the system starts.

Signs You Need a Replacement
