ICP 1-Pole 30A Contactor for WCH3314GKC100 — 24V Coil w/ Shunt | Ships Today

Overview

This OEM single-pole contactor (part #1172472) is the main switching relay for the ICP WCH3314GKC100 heat pump. Rated at 30 amps with a 24-volt control coil and integrated shunt, it passes line voltage to the compressor and outdoor fan motor whenever the thermostat calls for cooling or heating. Each time the 24V coil energizes, the contacts close under load; over years of cycling they pit, arc, and eventually weld shut or fail to make contact. A worn contactor is a leading cause of no-cool and no-start calls, often showing up as a buzzing condenser, contacts that stick closed so the unit won't shut off, or a system that ignores the thermostat entirely.

Specifications

Compatibility

Direct OEM fit for the ICP/Tempstar/Heil WCH3314GKC100 heat pump condensing unit, and a common service replacement across single-stage 24V residential condensers using a 1-pole 30A contactor. Confirm coil voltage and amp rating against your existing part before installing.

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 — Transfer the line, load, and 24V coil leads off the old contactor one terminal at a time.
5. Install — Mount the new contactor and reconnect each wire exactly per your photo.
6. Test — Restore power and confirm the contactor pulls in and the compressor and fan start on a call.

Signs You Need a Replacement

• Loud buzzing or humming at the outdoor unit
• Pitted, blackened, or welded contacts
• Compressor won't start or won't shut off
