What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCA036AKA1 — 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 TCA036AKA1 — 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 is the OEM single-pole contactor (part number 1050699) for the Tempstar TCA036AKA1 condensing unit. The contactor is the electrically operated switch that sends line voltage to your compressor and condenser fan motor every time the thermostat calls for cooling. A 24-volt signal energizes the coil, pulling the contacts closed so power flows to the outdoor unit. This 1-pole device is rated for 25 amps with a 24V coil. When it fails you'll typically see an outdoor unit that hums without starting, burnt or welded contacts, chattering, or a system that won't cool even though the thermostat is calling.
