ICP Contactor for RGS210HFAA0AAAA — 2-Pole 30A / 3-Pole 40A 24V | Ships Today

Overview

These OEM contactors for ICP / Tempstar / Heil model RGS210HFAA0AAAA cover both fitments used on the platform: a 2-pole 30A contactor (part 1171554) and a 3-pole 40A contactor (part 1172449), each with a 24V coil. A contactor is the high-current switch that delivers line voltage to the compressor and condenser fan motor when the thermostat calls for cooling — the 24V coil pulls the contacts closed. Contactors are among the most common HVAC failure points because their contacts arc and pit every time they open and close, eventually welding shut (system won't shut off) or burning open (system won't start).

Specifications

Compatibility

Fits ICP-family RGS-series equipment, including model RGS210HFAA0AAAA, and the broader Tempstar, Heil, and Comfortmaker lines that use a 24V-coil definite-purpose contactor. Match your existing pole count (2 vs 3) and amp rating before ordering.

Installation Guide

1. Safety First — Disconnect power at the breaker and disconnect, then verify zero voltage with a multimeter across the line terminals.
2. Access — Remove the service panel to expose the contactor.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer wires one at a time or label them, then unscrew the old contactor from its mounting.
5. Install — Mount the new contactor and reconnect each wire to the matching terminal per your photo.
6. Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor/fan energize.

Signs You Need a Replacement

• Compressor won't start or won't shut off (welded contacts)
• Loud buzzing or chattering from the contactor
• Visibly burnt, pitted, or blackened contacts
• Ants or debris jamming the contacts open
