Tempstar 1-Pole 25A Contactor for TCH430AKD1 — 24V Coil OEM 1050699 | Ships Today

Overview

This is the genuine OEM 1-pole, 25-amp definite purpose contactor with a 24V coil (part number 1050699) for the Tempstar TCH430AKD1 condensing unit. The contactor is the electromechanical switch that sends line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V control coil pulls the contacts closed; when the call ends, the contacts open and stop the compressor. Contactors are a high-wear part — the contacts pit and burn over thousands of cycles. A failed contactor causes a unit that won't start, chatters, or won't shut off because the contacts have welded together.

Specifications

Compatibility

Built for the Tempstar TCH430AKD1 and compatible across ICP, Heil, and Comfortmaker condensing units using a 1-pole 25A contactor with a 24V coil. Verify pole count, amperage, and coil voltage against your old contactor before installing.

Installation Guide

1. Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage across the line terminals with a multimeter.
2. Access — Remove the condensing unit service panel.
3. Document — Photograph every wire and terminal position before disconnecting.
4. Remove — Transfer wires one at a time or label them, then unscrew the old contactor from its mounting feet.
5. Install — Mount the new contactor, then move each wire to the matching terminal per your photo (line, load, and 24V coil leads).
6. Test — Restore power, call for cooling, and confirm the contacts pull in and the compressor and fan start cleanly.

Signs You Need a Replacement

• Compressor and fan won't start on a cooling call
• Loud humming or chattering at the contactor
• Unit won't shut off (welded/stuck contacts)
• Visible pitting, burning, or arcing on the contact points
