ICP Contactor for WJH330000KTP0A2 – 1-Pole 30A 24V Coil w/ Shunt | Ships Today

Overview

This is a genuine OEM single-pole definite purpose contactor (Part #1172472) for the ICP/Tempstar/Heil WJH330000KTP0A2 heat pump. The contactor is the electromechanical relay that switches line voltage to the outdoor compressor and condenser fan whenever the 24V control circuit calls. When the coil energizes, the contacts close and power the unit; when the call ends, the spring opens them. This contactor is rated 30 amps with a 24V coil and includes an integrated shunt. Burned, pitted, or welded contacts are a leading cause of an outdoor unit that hums without starting, runs intermittently, or trips its breaker.

Specifications

Compatibility

Factory-correct contactor for the ICP/Tempstar/Heil WJH330000KTP0A2, and a direct replacement across many ICP-family condensers and heat pumps using a 1-pole, 30A, 24V-coil contactor. Confirm amp rating, pole count, and coil voltage match your existing contactor before installing.

Installation Guide

1. Safety First – Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
2. Access – Remove the condenser unit's electrical access panel.
3. Document – Photograph all wire connections before disconnecting anything.
4. Remove – Transfer or label the wires one at a time, then unbolt 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 on a call and the compressor and fan start normally.

Signs You Need a Replacement
