What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH218AKC2 — Single Pole | 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 TCH218AKC2 — Single Pole | 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 genuine Tempstar OEM single-pole contactor (part number 1050699) is rated 25 amps with a 24V coil and switches the high-voltage power to the compressor and condenser fan on the TCH218AKC2 heat pump. When the thermostat calls, the 24V control signal energizes the coil, pulling the contacts closed to send line voltage to the outdoor unit. With age the contacts pit, arc, and burn, producing chatter, hard starts, or a unit that won't run. A 24V coil that opens prevents the contactor from pulling in, so the compressor stays dead even with the thermostat calling for operation.
