What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH424AKD1 — 24V Coil OEM 1050699 | 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.

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 OEM single-pole contactor (Part #1050699, "CONTACTOR 1P 25A 24V") is the primary switching relay for the Tempstar TCH424AKD1 condensing unit. Rated for 25 amps with a 24-volt control coil, the contactor closes its line-voltage contacts when the thermostat sends a 24V call, energizing the compressor and condenser fan motor. As one of the highest-cycling components in the system, contactors wear out from arcing and pitted contacts — a leading cause of "unit won't start" and "hums but won't run" service calls. Replacing a worn 25A contactor restores clean, reliable switching and protects the compressor from chatter and low-voltage damage.
