Overview

This is a genuine OEM 2-pole definite purpose contactor (part number 1171554) for the ICP/Tempstar/Heil RGS210LTAA0AAAA. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor whenever the 24-volt control circuit calls for cooling. Rated at 30 amps per pole with a 24V coil, it uses an electromagnetic coil to pull two sets of line-voltage contacts closed. Over time the contacts pit, burn, and weld from the constant arcing of every start and stop. When that happens the outdoor unit may hum but not start, run continuously even after the thermostat is satisfied, or trip the breaker. Replacing a worn contactor is one of the most common and least expensive ways to restore reliable cooling.

Compatibility

Designed as a direct-fit replacement for the ICP/Tempstar/Heil RGS210LTAA0AAAA. This 30A 24V 2-pole contactor is also a common service part across many comparable ICP-family condensing units. Always confirm the existing contactor's amp rating, pole count, and coil voltage match before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condenser service panel to expose the control area.
Document — Photograph every line, load, and coil wire before disconnecting anything.
Remove — Label and disconnect the L1/L2 line leads, the T1/T2 load leads, and the two 24V coil wires, then unscrew the old contactor from the bracket.
Install — Mount the new contactor and reconnect each wire exactly as photographed.
Test — Restore power, call for cooling, and confirm the contacts pull in cleanly and the compressor and fan start.
