ICP 2-Pole 30A Contactor for RHS090S0AB0AAAA — 30A 24V Coil | Ships Today

Overview

This is a genuine OEM 2-pole definite-purpose contactor (part number 1178074) for the ICP/Heil/Tempstar RHS090S0AB0AAAA heat pump. The contactor is the high-voltage switch that powers the compressor and outdoor condenser fan motor. When the thermostat calls for cooling or heating, the 24V control circuit energizes the contactor coil, which pulls the contacts closed and sends line voltage to the compressor. Rated for 30 amps with a 24-volt coil, it is the single most common failure point in any outdoor condensing unit. Failed contactors cause no-cool and no-heat calls, chattering or buzzing at the unit, pitted or welded contacts that won't release, and a compressor that won't start even though the thermostat is calling.

Specifications

Compatibility

Engineered as the factory replacement for the ICP RHS090S0AB0AAAA heat pump and shares the same form, fit and function across the RHS090 family. Because it is a 30A 24V 2-pole definite-purpose contactor, it also services many other Heil, Tempstar, Comfortmaker and ICP-built outdoor units that use the same coil voltage and amp rating. Always confirm your existing contactor is a 2-pole, 30A unit 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 at the contactor line terminals.
2. Access — Remove the condensing unit's electrical access panel.
3. Document — Photograph every wire and terminal position before disconnecting anything.
4. Remove — Note the line, load, and 24V coil leads, transfer wires one at a time, and unscrew the old contactor from its bracket.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power, place a cooling/heating call, and confirm the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement

• Loud buzzing, humming, or chattering from the outdoor unit.
• Burned, pitted, or welded contacts that stick closed.
• Compressor and condenser fan won't start on a cooling/heating call.
• Visible arcing, melted housing, or ant/debris intrusion across the contacts.
