What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH224AKC3 — 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 TCH224AKC3 — 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 genuine OEM single-pole 25-amp contactor (part number 1050699) is the high-voltage switch that powers the compressor and condenser fan in your Tempstar TCH224AKC3. When the thermostat calls for cooling, the 24V control circuit energizes the contactor's coil, pulling the contacts closed and sending line voltage to the compressor. Contactors are one of the most failure-prone parts in any condensing unit because their contacts arc every time they open and close, eventually pitting, welding, or burning. A failed contactor shows up as a unit that hums but won't start, contacts that stick closed so the compressor runs continuously, or chattering as the coil struggles to hold. This 1-pole, 25A unit with a 24V coil is a direct replacement that restores reliable switching.
