ICP 2-Pole 30A 24V Contactor for RGS240SRAA0AAAA — Definite Purpose Relay | Ships Today

Overview

This genuine OEM 2-pole definite purpose contactor (part #1171554) is the high-voltage switching relay for the ICP RGS240SRAA0AAAA. Rated at 30 amps with a 24-volt control coil, it energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V signal reaches the coil, the contactor's magnetic field pulls the contacts closed, sending line voltage to the compressor. Failed contactors are one of the most common no-cool service calls: pitted or welded contacts, a burned-out coil, or a buzzing/chattering hum that prevents the unit from starting reliably.

Specifications

Compatibility

Directly fits the ICP/Tempstar/Heil RGS240SRAA0AAAA gas furnace/condensing unit and many other ICP-family 2-ton through 5-ton systems that use a 2-pole 30A definite purpose contactor with a 24V coil. Always confirm pole count, amp rating, and coil voltage against the failed part before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and the outdoor disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the service panel from the condensing unit or control compartment.
3. Document — Photograph all wire positions before disconnecting anything.
4. Remove — Note the line, load, and 24V coil terminals, disconnect each wire, then unscrew the old contactor from the mounting bracket.
5. Install — Mount the new contactor and reconnect every wire exactly as photographed.
6. Test — Restore power, call for cooling, and confirm the contacts pull in cleanly with no buzzing.

Signs You Need a Replacement

• Unit won't start or only starts intermittently on a cooling call
• Loud buzzing, humming, or chattering from the contactor
