ICP 2-Pole 40A Contactor for ZAEB010CSA1 — 24V Coil OEM | Ships Today

Overview

This OEM 2-pole definite purpose contactor (part number 1066570) is the high-voltage switch that energizes the compressor and condenser fan motor in your ICP ZAEB010CSA1 package unit. On a cooling call, the 24V coil pulls the contacts closed and routes line voltage to the compressor and fan. Rated at 40 amps with a 24-volt coil, it is built to absorb the high inrush current of compressor start-up. Because it cycles thousands of times per season, the contactor is a common wear item — the contacts pit and arc until they either weld shut (unit never shuts off) or fail to close (unit hums but won't start). Insects nesting in the housing or a chattering coil are also frequent reasons to replace it.

Specifications

Compatibility

Factory replacement for the ICP/Tempstar/Heil ZAEB010CSA1 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
