ICP 2-Pole 30A Contactor 24V for RGS120HTBB0AAA — OEM | Ships Today

Overview

This is the genuine OEM ICP contactor (part 1178074): a 2-pole, 30-amp electromechanical contactor with a 24-volt coil. The contactor is the high-current switch that the 24V control circuit uses to energize the compressor and condenser fan. When the thermostat calls for cooling, 24V applied to the coil pulls the contacts closed, sending line voltage to the load; when the call ends, the contacts open. Contactors are a leading wear item — their contacts pit, burn, and weld over thousands of cycles. A failing contactor causes no-cool conditions, a unit that won't shut off (welded contacts), chattering, or buzzing. The 30A rating and 24V coil must match the original to switch the load safely.

Specifications

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil RGS120HTBB0AAA and other ICP-family units originally equipped with a 2-pole 30A 24V contactor. Confirm pole count, amp rating, and coil voltage against your existing contactor before ordering.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker; verify zero voltage at the contactor with a multimeter.
2. Access — Remove the electrical service panel.
3. Document — Photograph all line, load, and coil wires before disconnecting.
4. Remove — Transfer wires one at a time, or unscrew the old contactor from its mount after labeling.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor and fan energize.

Signs You Need a Replacement

• Unit won't start on a cooling call (open/burnt contacts).
• System won't shut off — contacts welded closed.
• Loud chattering or buzzing from the contactor.
• Visibly pitted, blackened, or melted contact surfaces.
