ICP 2-Pole 30A 24V Contactor for RGS210STAA0AAAA | Ships Today

Overview

This genuine OEM 2-pole definite-purpose contactor (part number 1171554) for ICP, Tempstar, and Heil systems switches up to 30 amps across two poles using a 24-volt control coil. The contactor is the main switching relay for the compressor and condenser fan motor — when the thermostat calls for cooling, the 24V coil pulls the contacts closed and sends line voltage to the outdoor unit. Pitted, burned, or chattering contacts are one of the most common no-cool failures. Replacing a worn contactor restores clean, reliable starts and prevents intermittent operation that hard-starts and overheats the compressor.

Compatibility

Direct-fit replacement for ICP / Tempstar / Heil model RGS210STAA0AAAA and other units that use the 1171554 30A 24V 2-pole contactor. Verify your existing contactor's amp rating, coil voltage, and pole count before installing.

Installation Guide

1. Safety First – Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
2. Access – Remove the service panel on the condensing unit or air handler.
3. Document – Photograph all line, load, and 24V coil connections before disconnecting.
4. Remove – Transfer wires one at a time or label them, then unscrew the old contactor from the bracket.
5. Install – Mount the new contactor, reconnect line/load and the 24V coil leads exactly per your photo.
6. Test – Restore power and confirm the contactor pulls in on a cooling call and energizes the compressor and fan.

Signs You Need a Replacement

• Outdoor unit won't start or starts intermittently on a cooling call.
• Loud buzzing or chattering from the contactor.
