ICP Single-Pole 30A Contactor for WCA5244GKA101 — 24V Coil w/ Shunt | Ships Today

Overview

This OEM single-pole definite purpose contactor (part number 1172472) is the electrical switch that energizes the compressor and condenser fan motor in your ICP / Tempstar / Heil WCA5244GKA101 condensing unit. When the thermostat calls for cooling, the 24-volt coil pulls in the main contacts, sending line voltage to the outdoor components. This unit is rated for 30 amps and includes a shunt, allowing it to safely carry and switch the full inductive load of the system. Contactors are a high-wear part because the contacts arc every time they open and close. Common failure symptoms include pitted or welded contacts, a chattering or buzzing coil, an outdoor unit that won't start, or a condenser that runs continuously and won't shut off. Replacing a worn contactor restores reliable starts and protects the compressor from voltage drop and chatter damage.

Specifications

Compatibility

Direct OEM fit for the ICP / Tempstar / Heil model WCA5244GKA101 condensing unit. This is the factory-specified contactor for that system. It also serves as a correct replacement across many ICP-family air conditioners and heat pumps that originally shipped with part 1172472. Always confirm your existing contactor is a 1-pole, 30A unit with a 24V coil before installing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
2. Access — Remove the condensing unit service panel to expose the electrical compartment.
3. Document — Photograph all wire positions before disconnecting anything.
4. Remove — Note the line, load, and 24V coil leads, then remove them. Unscrew the old contactor from the bracket and lift it out.
5. Install — Mount the new contactor, then reconnect every wire exactly as shown in your photo.
6. Test — Restore power and place a cooling call; confirm the coil pulls in smoothly and the compressor and fan start.

Signs You Need a Replacement

• Outdoor unit hums or buzzes but the compressor won't start.
• Visibly pitted, burned, or welded contacts.
• Condenser runs nonstop and won't shut off when the call ends.
• Loud chattering from the contactor coil during operation.
