Overview
This is a genuine OEM single-pole contactor (Part #1050699) for the Tempstar TCH018AKC3 condensing unit. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. When the 24V control signal energizes the coil, the contacts pull in and pass line voltage to the outdoor unit. This is a 1-pole, 25-amp device with a 24-volt holding coil. Contactors are one of the most common failure points in an air conditioner because the contacts arc and pit every time they open and close. A failed contactor is the leading cause of a unit that hums but won't start, or one where the outdoor fan and compressor refuse to run even though the thermostat is calling.

Compatibility
Engineered as a direct OEM replacement for the Tempstar TCH018AKC3 outdoor unit. The 1050699 contactor is also shared across many comparable ICP-family condensing units sold under the Heil, Comfortmaker, and Tempstar nameplates. Always confirm your existing contactor is a 1-pole, 25A, 24V coil device before ordering.
Installation Guide
- Safety First – Disconnect power at the outdoor disconnect and main breaker. Verify zero voltage at the contactor terminals with a multimeter.
- Access – Remove the condenser service panel to expose the control box.
- Document – Photograph every wire and terminal position before disconnecting anything.
- Remove – Label and disconnect the line, load, and 24V coil wires, then unscrew the old contactor from its mounting bracket.
- Install – Mount the new 1050699 contactor and reconnect each wire exactly per your photo.
- Test – Restore power and confirm the contacts pull in on a cooling call and the compressor/fan energize.
Signs You Need a Replacement
- Outdoor unit hums but compressor and fan don't start.
- Visible burnt, pitted, or welded contacts.
