What amp contactor do I need for my Tempstar system?

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 electrically operated switch that powers the outdoor unit on your Tempstar TCA224AKA1 air conditioner. With a 25-amp contact rating and a 24-volt control coil, it engages on a cooling call from the thermostat and routes line voltage to the compressor and condenser fan motor. Because it switches high current every cycle, the contacts gradually pit, oxidize, and burn — eventually welding closed or failing to make contact. Typical symptoms of a worn contactor include an outdoor unit that buzzes but won't start, won't energize at all, or won't turn off. Replacing this inexpensive part restores dependable cooling.
