ICP 1-Pole 30A Contactor for WPG4244040RKB1 — 24V Coil w/Shunt | Ships Today

Overview

This OEM single-pole 30A contactor with a 24V coil and integrated shunt is the electrical switch that energizes the compressor and condenser fan in your ICP WPG4244040RKB1. When the thermostat calls for cooling, the 24V coil pulls the contacts closed to pass line voltage to the compressor; when the call ends, the contacts open. Contactors are a leading cause of no-cool service calls — the contacts pit, burn, and weld from constant arcing, or the coil opens so the contactor never pulls in. A buzzing or chattering contactor, visibly burned contacts, or a compressor that will not start despite a good capacitor all point to a failed contactor. This is part 1172472 (CONTACTOR 1P 30A 24V W/SHUNT).

Specifications

Compatibility

Direct OEM replacement for the ICP/Heil/Tempstar WPG4244040RKB1 packaged unit and other ICP-family condensing units using a 1-pole 30A definite-purpose contactor with a 24V coil. Confirm pole count, amp rating, and 24V coil before installing.

Installation Guide

1. Safety First — Disconnect power and verify zero voltage with a multimeter at the contactor line terminals.
2. Access — Remove the electrical service panel.
3. Document — Photograph all line, load, and 24V coil connections before disconnecting.
4. Remove — Transfer wires one at a time, then unscrew the old contactor from the 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 cooling call and passes line voltage to the load.

Signs You Need a Replacement

• Buzzing, humming, or chattering at the contactor.
• Pitted, burned, or welded contacts.
• Compressor and fan will not start on a cooling call with a good capacitor.
• Coil reads open on a multimeter.
