ICP 2-Pole 24V Definite Purpose Contactor for RGS150HEBA0AGAA — 30A / 40A | Ships Today

Overview

This genuine OEM 2-pole definite-purpose contactor energizes the compressor and condenser fan circuits in the ICP / Tempstar / Heil RGS150HEBA0AGAA. The contactor is controlled by a 24V coil: when the thermostat calls for cooling, the low-voltage coil pulls the contacts closed and passes line voltage to the load. Two amperage ratings fit this model — 30A (P/N 1178074) and 40A (P/N 1178211); select the rating that matches your existing contactor or the unit's wiring diagram. Contacts pit, weld, and burn over thousands of cycles, which is one of the most common causes of a no-cool call.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter on both line terminals.
2. Access — Remove the service/electrical panel.
3. Document — Photograph every wire and terminal position before disconnecting.
4. Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from its mount.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo, confirming coil leads land on the coil terminals.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter or arcing.

Signs You Need a Replacement

• Compressor/condenser won't start on a cooling call
• Buzzing, chattering, or humming at the contactor
• Pitted, blackened, or welded contacts
• Visible arcing or a burnt-plastic smell at the electrical panel
