What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH030AKA2 — 25 Amp | 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 TCH030AKA2 — 25 Amp | 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 genuine OEM single-pole 25-amp contactor (part number 1050699) is the switching relay for the Tempstar TCH030AKA2. Its 24-volt coil closes a 25A power contact to energize the compressor and condenser fan whenever the thermostat calls for cooling. As a high-cycle wear item, contactor contacts arc and pit with every start; over time they weld closed (system runs nonstop), fail to pull in (no cooling), or buzz and chatter. Installing a fresh 25A / 24V contactor restores dependable switching and helps protect the compressor from inrush and voltage faults.
