ICP 2-Pole 30A 24V Contactor for RGS091LRAB0AAAA — OEM 1178074 | Ships Today

Overview

This genuine OEM 2-pole, 30-amp, 24-volt contactor (part number 1178074) is the replacement switching relay for the ICP Tempstar/Heil RGS091LRAB0AAAA. The contactor is an electrically operated switch: when the thermostat calls and energizes the 24V coil, the contactor pulls in and closes both line-voltage poles, sending power to the compressor and condenser fan motor. Contactors are high-wear parts — the contacts arc and pit with every cycle. A failing contactor causes hard starts, chattering, welded contacts that won't release, or a unit that won't energize at all. Replacing it with the correct OEM-rated part restores reliable, clean switching.

Specifications

Compatibility

Fits the ICP Tempstar/Heil RGS091LRAB0AAAA and other ICP-family condensing units using a 2-pole 30A 24V definite-purpose contactor. Verify pole count, amp rating, and coil voltage against your old part before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter across the contactor terminals.
2. Access — Remove the unit's electrical access panel.
3. Document — Photograph every wire and terminal location before disconnecting anything.
4. Remove — Transfer wires one at a time or label them, release the mounting screws, and remove the old contactor.
5. Install — Mount the new contactor, then reconnect each line, load, and 24V coil wire exactly per your photos.
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

• Loud chattering or buzzing from the contactor when energized.
• Burnt, pitted, or welded contacts that won't open or close.
• Compressor and condenser fan won't start on a cooling call.
• Visible arcing, melted housing, or a sticking armature.
