Tempstar 1-Pole Contactor for TCA030AKC3 — 25A 24V Coil | Ships Today

Overview

This is the OEM single-pole contactor (part number 1050699) for the Tempstar TCA030AKC3 condensing unit. The contactor is the electrically operated switch that passes line voltage to your compressor and condenser fan motor each time the thermostat calls for cooling. A 24-volt signal energizes the coil, closing the contacts so power reaches the outdoor unit. This 1-pole device is rated for 25 amps with a 24V coil. When it fails, you'll commonly see an outdoor unit that hums without starting, burnt or welded contacts, chattering, or a system that won't cool despite an active thermostat call.

Specifications

Compatibility

This is the factory-correct replacement contactor for the Tempstar TCA030AKC3 air conditioning condenser. The identical 1050699 contactor is shared across many ICP-family outdoor units sold under the Tempstar, Heil, and Comfortmaker brands. Verify your current part is a 1-pole, 25A, 24V coil contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage at the terminals with a multimeter.
2. Access — Remove the condenser's electrical service panel.
3. Document — Photograph all wiring before disconnecting anything.
4. Remove — Label and disconnect the line, load, and 24V coil leads, then unbolt the old contactor.
5. Install — Mount the new contactor and reconnect each wire to its matching terminal using your photo as a guide.
6. Test — Restore power and confirm the contactor pulls in and the outdoor unit starts on a cooling call.
