ICP 2-Pole 30A Contactor for RGS210LECA0AAAA — 24V Coil | Ships Today

Overview

This is a genuine OEM 2-pole definite purpose contactor (Part No. 1171554) for the ICP / Tempstar / Heil RGS210LECA0AAAA system. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24-volt signal from the control board pulls in the coil, closing two sets of 30-amp line-voltage contacts and sending power to the outdoor unit. When the contactor fails, the high-amperage contacts pit, burn, or weld — the most common cause of an outdoor unit that hums but won't start, won't shut off, or buzzes loudly. Replacing a worn contactor restores clean switching and protects the more expensive compressor from chatter and short-cycling.

Specifications

Compatibility

Engineered as the factory replacement for the ICP RGS210LECA0AAAA. It also serves as a direct fit for many Tempstar, Heil, and Comfortmaker condensing units that use a 2-pole 30A / 24V definite purpose contactor. Always confirm the original part number (1171554) and coil voltage before installing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter across the contactor terminals.
2. Access — Remove the condenser service panel to expose the contactor.
3. Document — Photograph every wire and terminal position before disconnecting anything.
4. Remove — Label and pull the line, load, and 24V coil leads, then unscrew the old contactor from the bracket.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo (L1/L2 line in, T1/T2 to compressor and fan, 24V to coil terminals).
6. Test — Restore power and confirm the contactor pulls in on a cooling call and drops out cleanly when satisfied.

Signs You Need a Replacement

• Outdoor unit hums or buzzes but the compressor and fan won't start.
• Visible pitting, burning, or melted plastic on the contact points.
• Unit won't shut off because the contacts have welded closed.
• Chattering or rapid clicking from the contactor during operation.
