What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCH636GKA200 — 1-Pole 30A 24V Coil with Shunt | 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 OEM definite-purpose contactor (part number 1172472) is the electrical switch that energizes the compressor and condenser fan motor in your Tempstar TCH636GKA200 condensing unit. It is a single-pole (1-pole) design rated for 30 amps with a 24-volt control coil and includes an integrated shunt for reliable load switching. When the thermostat calls for cooling, the 24V coil pulls the contacts closed, sending line voltage to the outdoor unit. Over time the contact points pit, burn, and weld from the constant high-current arcing — a failing contactor is one of the most common causes of an outdoor unit that won't start, hums but won't engage, or fails to shut off. Replacing it with the correct 30A 24V OEM part restores dependable starts and protects the more expensive compressor it controls.

Compatibility

Designed as the factory replacement contactor for the Tempstar TCH636GKA200 condensing unit.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter before touching any terminals.
Access — Remove the service/electrical access panel on the condensing unit.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Note line, load, and 24V coil leads, then transfer wires one at a time off the old contactor and unscrew it from the bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the coil leads are on the 24V terminals.
Test — Restore power, call for cooling, and verify the contacts pull in and the unit starts cleanly.

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.
