Overview

This is a genuine OEM single-pole definite-purpose contactor (Part No. 1050699) for the ICP / Tempstar / Heil YJ042G2 heat pump. The contactor is an electromagnetic switch that uses a low-voltage 24V control signal from the thermostat to close its line-voltage contacts and energize the compressor and condenser fan motor. Rated at 25 amps with a 24-volt coil, it is the workhorse relay of the outdoor unit — every cooling and heating call passes through it. When a contactor fails, the contacts pit, burn, or weld from the constant arcing, and the coil can burn open. Common symptoms include the outdoor unit failing to start, a chattering or buzzing sound, contacts that stick closed so the unit never shuts off, or visible burning and melting on the terminals.

Compatibility

Engineered for the ICP YJ042G2 and shared across the ICP family of brands including Tempstar, Heil, Comfortmaker, and Arcoaire condensing units and heat pumps that use a 25A single-pole, 24V-coil contactor. Always confirm the existing part number and coil voltage before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor line terminals with a multimeter.
Access — Remove the condenser service/electrical panel.
Document — Photograph all wire connections before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from its mounting bracket.
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 the coil terminals).
Test — Restore power, place a cooling/heating call, and confirm the contactor pulls in cleanly and the compressor and fan energize.
