ICP 2-Pole 30A Contactor 24V Coil for RGS300LEFA0AAAA — OEM 1171554 | Ships Today

Overview

This is the genuine OEM 2-pole, 30 amp contactor with a 24-volt control coil (part number 1171554) for the ICP Tempstar Heil RGS300LEFA0AAAA unit. The contactor is the high-current switch that energizes the compressor and condenser fan whenever the thermostat calls for cooling — the 24V coil pulls the contacts closed to pass line voltage to the load. Over time the contacts pit, weld, or burn and the coil weakens, causing failures such as a unit that won't start, chattering or buzzing at the contactor, intermittent operation, or a compressor that won't shut off. Replacing a worn contactor restores clean, reliable switching and protects the rest of the electrical circuit.

Specifications

Compatibility

This contactor is the factory-specified replacement for the ICP Tempstar Heil RGS300LEFA0AAAA unit and equivalent ICP-built equipment sold under the Tempstar, Heil, and Comfortmaker badges. The 2-pole, 30A, 24V-coil configuration is also a common direct-fit upgrade for many condensing units — verify pole count, amp rating, and coil voltage against your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter at the contactor terminals.
2. Access — Remove the electrical-access service panel on the condenser.
3. Document — Photograph all line, load, and 24V coil wiring before disconnecting.
4. Remove — Transfer one wire at a time, or label leads, then remove the mounting screws and the old contactor.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal (line, load, and the two coil leads) per your photo.
6. Test — Restore power and run a cooling cycle to confirm the contactor pulls in cleanly with no chatter and the compressor and fan energize.

Signs You Need a Replacement

• Contactor chatters, buzzes, or hums when energized
• Pitted, burned, or welded contacts visible on inspection
• Compressor won't start or won't shut off
• Intermittent cooling or repeated tripping
