ICP Contactor 2-Pole 30A 24V Coil for RGS120HEAA0AGAA | Ships Today

Overview

This OEM 2-pole contactor (part #1178074) is the switching component that energizes the high-voltage circuit in your ICP Tempstar/Heil RGS120HEAA0AGAA furnace and condensing unit. Rated for 30 amps with a 24V control coil, the contactor closes when the thermostat calls for cooling, allowing line voltage to reach the compressor and condenser fan motor. When the coil weakens, the contacts pit, or the points weld shut, you'll see hard starts, chattering, a unit that won't shut off, or no cooling at all. Replacing a failing contactor early protects the more expensive compressor downstream.

Specifications

Compatibility

Direct OEM fit for ICP Tempstar Heil model RGS120HEAA0AGAA and shared-platform ICP-family equipment using a 2-pole 30A 24V contactor. Verify your existing contactor's pole count, amp rating, and coil voltage before ordering.

Installation Guide

1. Safety First – Disconnect power at the breaker and pull the disconnect; verify zero voltage with a multimeter across all line terminals.
2. Access – Remove the service panel on the condensing unit.
3. Document – Photograph every wire and terminal position before disconnecting.
4. Remove – Transfer the line, load, and 24V coil wires off the old contactor one at a time, then unscrew it from the bracket.
5. Install – Mount the new contactor and reconnect each wire exactly per your photo.
6. Test – Restore power and confirm the contactor pulls in cleanly on a cooling call with no chatter.

Signs You Need a Replacement

• Buzzing or chattering from the contactor
• Burned, pitted, or welded contacts
• Compressor won't start or won't shut off
• Ants or debris fouling the open contacts
