What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH024AKA1 — 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 TCH024AKA1 — 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 compressor and condenser fan on your Tempstar TCH024AKA1 heat pump. On a call from the thermostat, the 24V control circuit energizes the contactor coil, closing the contacts and feeding line voltage to the compressor. Rated for 25 amps with a 24-volt coil, the contactor endures constant inrush current and arcing, making it one of the most common HVAC wear parts. Typical failures include a unit that hums but won't start, buzzing or chattering at the contactor, and pitted or welded contacts.
