Overview
This is a genuine OEM 1-pole definite purpose contactor (part #1050699) for the Tempstar TCH230AKC1 heat pump. The contactor is the high-current relay that switches line voltage to the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. Its 24V coil energizes a single pole rated for 25 amps, pulling the contacts closed to start the outdoor unit. Contactors are a common wear item: every cooling cycle arcs the contacts slightly, and over thousands of cycles the points pit, burn, or weld. Failure symptoms include a buzzing or chattering outdoor unit, a contactor that won't pull in, pitted or melted contacts, or a compressor that keeps running because the points have welded shut.

Compatibility
Engineered for the Tempstar TCH230AKC1 heat pump and shared across many ICP/Heil/Comfortmaker condensing units that use the same 1-pole 25A 24V contactor platform. Always confirm your old contactor's pole count, amp rating, and 24V coil before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor with a multimeter.
- Access — Remove the condensing unit's electrical access panel.
- Document — Photograph every wire and terminal before disconnecting anything.
- Remove — Note line, load, and 24V coil leads, then transfer wires one at a time off the old contactor and unscrew it from the bracket.
- Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm tight connections.
- Test — Restore power, call for cooling, and verify the contactor pulls in cleanly with no chatter.
Signs You Need a Replacement
- Loud buzzing or chattering from the outdoor unit
- Pitted, burned, or welded contacts
- Compressor won't start even with a 24V signal at the coil
