ICP 2-Pole 40A Contactor for ZAEB015CHA1 — 24V Coil OEM | Ships Today

Overview

This OEM 2-pole definite purpose contactor (part number 1066570) is the high-voltage switch that powers the compressor and condenser fan motor in your ICP ZAEB015CHA1 package unit. When the thermostat calls for cooling, the 24V coil energizes and pulls the contacts closed, sending line voltage to the compressor and fan. Rated for 40 amps with a 24-volt coil, it handles the heavy inrush current of compressor startup. Contactors are one of the most common HVAC failure points: the contacts pit, arc, and burn over thousands of cycles, eventually welding shut (unit runs nonstop) or failing to close (unit hums but won't start). Ants, debris, or a chattering coil are all reasons to replace this wear item.

Specifications

Compatibility

Factory replacement for the ICP/Tempstar/Heil ZAEB015CHA1 package system. Confirm pole count, amp rating, and 24V coil voltage against your existing contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the breaker and unit disconnect, then verify zero voltage with a multimeter.
2. Access — Remove the unit's electrical access panel.
3. Document — Photograph all line, load, and 24V coil wires before disconnecting.
4. Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its bracket.
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 cleanly on a cooling call with no chatter.

Signs You Need a Replacement

• Compressor and fan won't start, but the coil hums or buzzes
• Pitted, burned, or welded contacts visible on inspection
• Unit runs continuously and won't shut off (contacts stuck closed)
• Chattering or clicking when the thermostat calls for cooling
