Overview
This genuine OEM contactor fits the ICP / Heil / Tempstar RGS181HEBB0AGAA system. The contactor is the high-current relay that switches line voltage to the compressor and condenser fan motor whenever the 24-volt control circuit calls for cooling. The primary part 1171554 is a 2-pole, 30-amp contactor with a 24V coil; a heavier-duty 3-pole, 40-amp option (part 1172449, also 24V coil) is available for higher-load applications. Contactors fail from pitted or welded contacts, a burned-out coil, or chattering caused by low control voltage — leading to a system that won't start, won't shut off, or buzzes loudly. A fresh contactor restores clean, reliable switching and protects the compressor from damaging voltage drops.

Compatibility
Designed as a factory replacement for the ICP RGS181HEBB0AGAA and matching Heil, Tempstar, and Comfortmaker systems. Confirm your existing contactor's pole count (2 vs. 3), contact amp rating, and 24V coil before ordering so the new unit drops straight in.
Installation Guide
- Safety First — Disconnect line and control power at the disconnect and breaker. Verify zero voltage at the contactor line terminals with a multimeter.
- Access — Remove the electrical-compartment service panel.
- Document — Photograph all line, load, and 24V coil connections before disconnecting.
- Remove — Transfer wires one at a time or label them, unscrew the contactor from its bracket, and remove it.
- Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the 24V coil leads are secure.
- Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with no chatter and the compressor/fan energize.
Signs You Need a Replacement
- System won't start, or the contactor doesn't pull in on a cooling call.
- Loud buzzing, humming, or chattering at the contactor.
- Pitted, burned, or welded contacts that keep the compressor running.
- Burned coil or melted housing around the terminals.
