What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH024AKC1 — 1-Pole 25A 24V Coil | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications. Using a part with different specifications can cause equipment damage or void your warranty. You can verify this by checking the data plate on your Tempstar equipment which lists the model number TCH024AKC1 — 1-Pole 25A 24V Coil | Ships Today.

My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This OEM single-pole definite purpose contactor (part number 1050699) is the electrical switch that energizes the outdoor compressor and condenser fan on your Tempstar TCH024AKC1 heat pump. When the thermostat calls for cooling or heating, the 24V control circuit energizes the contactor's coil, pulling the contacts closed and sending line voltage to the compressor. Rated for 25 amps with a 24-volt coil, it is one of the most common wear items on any HVAC condensing unit. Failure symptoms include a unit that hums but won't start, chattering or buzzing at the contactor, pitted or welded contacts, or an outdoor unit that fails to run while the indoor blower operates normally.

Compatibility

Direct OEM replacement for the Tempstar TCH024AKC1 heat pump. The 1050699 contactor is also used across many ICP-family condensing units (Tempstar, Heil, Comfortmaker, Arcoaire) of similar tonnage. Always confirm your existing contactor is a 1-pole, 25A, 24V coil unit before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker. Verify zero voltage with a multimeter across the contactor terminals.
Access — Remove the condenser service panel to expose the control compartment.
Document — Photograph all line, load, and coil wires before disconnecting anything.
Remove — Label and disconnect the wires, then unscrew the old contactor from the mounting bracket.
Install — Mount the new 1050699 contactor, then reconnect each wire exactly per your photo (line in, compressor/fan out, 24V to coil terminals).
Test — Restore power and call for cooling. Confirm the contacts pull in cleanly and the compressor and fan start.
