ICP 1-Pole 30A Contactor for WCH3362GKA1 — 24V Coil w/ Shunt | Ships Today

Overview

This OEM single-pole contactor (part #1172472) is the primary switching relay for the ICP WCH3362GKA1 heat pump. Rated at 30 amps with a 24-volt control coil and an integrated shunt, it energizes the compressor and outdoor fan whenever the thermostat calls for cooling or heating. When the 24V coil pulls in, the silver-alloy contacts close and pass line voltage to the unit. Over thousands of cycles these contacts pit, arc, and weld, while the coil itself can burn out or chatter. A failed contactor is one of the most common causes of a no-cool or no-start condition, often presenting as a buzzing outdoor unit, contacts that stick closed, or a system that won't respond to the thermostat at all.

Specifications

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil WCH3362GKA1 heat pump condensing unit, and a common service replacement across single-stage 24V residential condensers using a 1-pole 30A contactor. Always confirm coil voltage and amp rating against your existing part.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter.
2. Access — Remove the condenser service panel.
3. Document — Photograph all line and low-voltage wires before disconnecting.
4. Remove — Note terminal positions, then transfer the line, load, and 24V coil leads off the old contactor one at a time.
5. Install — Mount the new contactor, reconnect each wire exactly per your photo.
6. Test — Restore power and confirm the contactor pulls in and the compressor/fan start on a call.

Signs You Need a Replacement

• Loud buzzing or humming from the outdoor unit
