ICP 2-Pole 30A Contactor for RHS072H0BA0AAAA – 24V Coil | Ships Today

Overview

This OEM 2-pole definite purpose contactor (part number 1178074) is the switching relay that energizes the compressor and condenser fan motor in your ICP RHS072H0BA0AAAA heat pump. Rated for 30 amps per pole with a 24-volt control coil, it closes when the thermostat calls for cooling and passes line voltage to the outdoor unit. Because the contacts arc on every cycle, contactors wear out over time — the contact faces pit, burn, or weld together after thousands of cycles. Typical failure symptoms include an outdoor unit that won't start, a loud chattering or buzzing hum, contacts stuck closed so the compressor never shuts off, or visible burning and pitting on the contacts.

Specifications

Compatibility

Directly fits the ICP RHS072H0BA0AAAA and is shared across many ICP-family condensers and heat pumps sold under the Tempstar, Heil, Comfortmaker, Arcoaire, and KeepRite brands that use a 2-pole 30A / 24V coil contactor. Confirm your existing contactor is 2-pole with a 24V coil 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 condenser service panel to expose the electrical compartment.
3. Document – Photograph every wire and terminal position before disconnecting anything.
4. Remove – Note the line, load, and 24V coil wire locations, transfer wires one at a time to the new contactor, and unscrew the old unit from its bracket.
5. Install – Mount the new contactor, reconnect each wire per your photo, and confirm the 24V coil leads are landed correctly.
6. Test – Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement

• Outdoor unit won't start or hums but won't engage
• Loud buzzing, chattering, or clicking at the contactor
• Pitted, burned, or melted contact surfaces
