ICP 1-Pole 30A Contactor for WJH336000KTP0A1 — 24V Coil with Shunt | Ships Today

Overview

This genuine OEM definite-purpose contactor (part number 1172472) is the single-pole, 30-amp switching relay for the ICP / Heil / Tempstar WJH336000KTP0A1 packaged heat pump. Its 24V coil pulls the contacts closed on a thermostat call, routing line voltage to the compressor and condenser fan; the integrated shunt provides the proper auxiliary connection for the unit's wiring. Contactors are high-wear parts — the contacts pit, arc, and weld over thousands of cycles. A failing contactor shows up as a unit that won't start, chatters, or won't shut off because the contacts have stuck closed. Replacing it restores clean, reliable switching.

Installation Guide

1. Safety First — Disconnect power at the breaker and verify zero voltage with a multimeter at the contactor line terminals.
2. Access — Remove the control-access service panel.
3. Document — Photograph every line, load, and 24V coil wire before disconnecting.
4. Remove — Transfer leads one at a time or tag them, then unscrew the old contactor from its mounting base.
5. Install — Mount the new OEM contactor, reconnect each lead per your photo, and confirm the shunt connection.
6. Test — Restore power and verify the contactor pulls in on a call and the compressor and fan energize.

Signs You Need a Replacement

• Unit won't start or hums without the compressor running
