Overview
This is a genuine OEM single-pole, 25-amp definite purpose contactor (P/N 1050699) with a 24V coil for the Tempstar TCH224AKC1. The contactor is the electrically operated switch that powers the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil pulls the contacts closed so they carry the high-voltage load to the compressor. With age the contacts pit, burn, and weld, and the coil can open. Symptoms of a failing contactor include a unit that won't start, chattering or buzzing at the contactor, contacts welded closed so the compressor never shuts off, and visible arcing or burnt contact faces.

Installation Guide
- Safety First – Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before touching any wiring.
- Access – Remove the condensing unit electrical access panel to expose the contactor.
- Document – Photograph every line, load, and 24V coil wire before disconnecting.
- Remove – Disconnect all wires, unscrew the contactor from its mounting bracket, and lift it out.
- Install – Mount the new contactor, then reconnect each wire to the matching terminal per your photo.
- Test – Restore power and call for cooling; confirm the contactor pulls in cleanly and the compressor and fan start.
