What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TSH424GKA101 — 24V Coil w/ 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. You can verify this by checking the data plate on your Tempstar equipment which lists the model number TSH424GKA101 — 24V Coil w/ Shunt | 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 is the OEM single-pole definite purpose contactor (Part No. 1172472) for the Tempstar TSH424GKA101 heat pump/condensing unit. Rated for 30 amps with a 24-volt coil and an integrated shunt, the contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. When the 24V coil is energized, the contacts pull in and pass line voltage to the outdoor unit; when the call ends, the contacts open and the unit shuts down. A worn or pitted contactor is one of the most common causes of an outdoor unit that hums, chatters, fails to start, or runs continuously.

Compatibility

Engineered as the factory replacement for the Tempstar TSH424GKA101 outdoor unit. The same 30A 1-pole 24V definite purpose contactor is used across many ICP-family condensers and heat pumps sold under the Tempstar, Heil, Comfortmaker, and Arcoaire brands. Always confirm your existing contactor's amp rating, pole count, and coil voltage before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condenser electrical access panel.
Document — Photograph every wire and terminal position before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil leads, then unscrew the old contactor from the bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo, and confirm the shunt orientation.
Test — Restore power and call for cooling; verify the contacts pull in cleanly and the compressor and fan energize.
