Overview

This is a genuine OEM 2-pole definite purpose contactor (part number 1066570) for the ICP/Tempstar/Heil ZAEB010CHA1 condensing unit. The contactor is an electrically operated switch that uses a 24-volt control signal from the thermostat to energize the high-voltage circuit feeding the compressor and condenser fan motor. Rated at 40 amps per pole with a 24V coil, it carries the full line-voltage load every time the system calls for cooling. A failed contactor leaves the unit unable to start, humming without engaging, or running nonstop if the contacts weld shut. Pitted, burned, or chattering contacts are the most common symptoms of a worn contactor on an aging air conditioning system.

Compatibility

Engineered as the factory replacement for the ICP/Tempstar/Heil ZAEB010CHA1. As a standard 40A 2-pole 24V definite purpose contactor, it also serves as a direct replacement on many comparable Carrier, Bryant, Comfortmaker, and Heil condensing units using the same control footprint. Always confirm coil voltage (24V) and amp rating before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condensing unit's electrical service 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 the bracket.
Install — Mount the new contactor and reconnect each wire exactly per your photo (line in on one side, compressor/fan on the load side, 24V to the coil terminals).
Test — Restore power and confirm the contactor pulls in on a cooling call and the compressor and fan energize.
