ICP 2-Pole Contactor for RGS101HDAB0AAAA — 30A/40A 24V Coil | Ships Today

Overview

This OEM 2-pole definite purpose contactor is the switching heart of your ICP RGS101HDAB0AAAA condensing unit. When the 24V control signal energizes the coil, the contactor closes and sends line voltage to the compressor and condenser fan motor. Available in 30A (part 1178074) and 40A (part 1178211) ratings, both with a 24-volt coil, this contactor handles the high-inrush demands of a starting compressor without burning or pitting prematurely. A failing contactor is one of the most common no-cool service calls — when the contacts pit, weld, or chatter, the outdoor unit either won't start or won't shut off.

Specifications

Compatibility

Engineered for the ICP RGS101HDAB0AAAA and the broader Tempstar/Heil/Comfortmaker family of gas furnace and condensing equipment using a 24V control circuit. Confirm your existing contactor's amp rating and coil voltage before ordering — match 30A to 30A or step up to 40A for added margin.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter across L1 and L2.
2. Access — Remove the condenser service panel to expose the control compartment.
3. Document — Photograph every wire and terminal before disconnecting anything.
4. Remove — Note line, load, and 24V coil leads, then transfer one wire at a time to the new contactor to avoid mistakes.
5. Install — Mount the new contactor in the same orientation and reconnect each lead per your photo.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter or buzz.

Signs You Need a Replacement

• Outdoor unit hums but compressor and fan won't start
• Pitted, blackened, or welded contacts
