ICP 1-Pole 23A Contactor for YA030 — 24V Coil | Ships Today

Overview

This genuine OEM single-pole definite-purpose contactor (part number 14306505) is the primary switching relay for the ICP/Heil/Tempstar YA030 condensing unit. Rated at 23 amps with a 24-volt control coil, it energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. The 24V coil pulls in a set of heavy-duty silver-alloy contacts that carry line voltage to the outdoor components. Over thousands of cycles these contacts pit, burn, and weld from arcing, while the coil itself can open or weaken. A failed contactor is one of the most common no-cool service calls — symptoms include a buzzing or chattering outdoor unit, a compressor that won't start, contacts that stick closed and run the unit non-stop, or no response at all from the condenser when the system calls for cooling.

Specifications

Compatibility

This contactor is the factory-specified switching relay for the ICP YA030 outdoor unit and the equivalent Heil, Tempstar, and Comfortmaker badged versions of the same platform. It is a direct, plug-in OEM replacement — no rewiring or adapters required. Always confirm your existing contactor is a single-pole, 23A, 24V coil unit before installing.

Installation Guide

1. Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching any wiring.
2. Access — Remove the service panel from the condensing unit to expose the contactor and control wiring.
3. Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
4. Remove — Note wire positions, disconnect the spade and lug terminals, then unscrew the old contactor from its mounting bracket.
5. Install — Mount the new contactor, then reconnect each wire to the matching terminal exactly per your photo (line in, load out, 24V on the coil terminals).
6. Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan energize without chatter.

Signs You Need a Replacement

• Loud buzzing, humming, or chattering from the outdoor unit
• Compressor and condenser fan won't start on a cooling call
• Pitted, burned, or welded contacts visible on the old part
• Unit runs continuously because contacts are stuck closed
