ICP 2-Pole Contactor for RHH120H0CA0AAAA — 30A/40A 24V Coil | Ships Today

Overview

This is a genuine OEM 2-pole definite-purpose contactor for the ICP / Heil / Tempstar RHH120H0CA0AAAA heat pump. The contactor is the electrically operated switch that sends line voltage to the compressor and condenser fan motor whenever the thermostat calls. A 24V control coil pulls the contacts closed; when they pit, burn, or weld, the outdoor unit can hum without starting, trip the breaker, or run intermittently. This part is offered in 30-amp (OEM 1178074) and 40-amp (OEM 1178211) ratings, both with a 24V coil.

Specifications

Compatibility

Direct-fit OEM replacement for the ICP-family RHH120H0CA0AAAA heat pump and shared platforms sold under the Heil, Tempstar, and Comfortmaker labels. Confirm pole count, 24V coil, and amp rating against your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the line terminals.
2. Access — Remove the condensing unit's electrical access panel.
3. Document — Photograph all line, load, and coil wiring before disconnecting.
4. Remove — Label and disconnect the wires, then unbolt the old contactor from its bracket.
5. Install — Mount the new contactor and reconnect line, load, and the two 24V coil leads exactly per your photo.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement
