What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH430AKA3 — 1-Pole 25A 24V | 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 TCH430AKA3 — 1-Pole 25A 24V | 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 contactor (part number 1050699) is the main switching relay for your Tempstar TCH430AKA3 condensing unit. Rated at 25 amps with a 24V control coil, it energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. A 24V signal closes the contacts and passes line voltage to the compressor. A worn contactor is one of the most common no-start failures: a humming unit that won't engage, pitted or welded contacts, a buzzing coil, or burnt terminals all indicate replacement is due. A new contactor restores reliable starts and protects the compressor from contact chatter.
