ICP 2-Pole 30A Contactor for RGS101LSBB0AAAA — 24V Coil OEM Relay | Ships Today

Overview

This is a genuine OEM 2-pole, 30-amp definite-purpose contactor with a 24-volt control coil (part #1178074) for ICP, Heil, Tempstar and Comfortmaker HVAC equipment associated with the RGS101LSBB0AAAA. The contactor is the high-voltage switch that powers the compressor and condenser fan motor. When the thermostat calls for cooling, 24V is applied to the coil, which pulls in the contacts and energizes the line-voltage circuit. Contactors are a common failure point because the contacts arc and pit with every cycle. Symptoms of a failing 30A contactor include burned or pitted contacts, a humming or chattering coil, contacts that weld closed (so the unit never shuts off), or contacts that no longer pull in (so the unit never starts). Replacing a worn 2-pole contactor restores reliable, clean switching and protects the compressor.

Specifications

Compatibility

Fits the ICP/Heil/Tempstar RGS101LSBB0AAAA and many other ICP-family condensing units and air handlers that use a 2-pole 30A contactor with a 24V coil. Confirm pole count, amp rating and coil voltage against your existing contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the contactor with a multimeter.
2. Access — Remove the unit's electrical access panel.
3. Document — Photograph all line, load and 24V coil wiring before disconnecting.
4. Remove — Label and transfer wires one at a time, then unbolt the old contactor from its base.
5. Install — Mount the new 2-pole contactor, land each wire exactly as photographed, and verify the 24V coil leads.
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement

• Burned, pitted or welded contacts
• Loud humming, buzzing or chattering coil
• System won't start (contacts won't close)
