What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4A624GKA200 – 1-Pole 30A 24V 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.

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 definite purpose contactor (part number 1172472) is the factory replacement switch for the Tempstar T4A624GKA200 heat pump. The contactor energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heating. A 24V control signal pulls the contactor in, closing its 30-amp line-voltage contacts; this unit includes an integrated shunt. Contactors are a high-wear part: every cooling or heating cycle the contacts open and close under load, so they eventually pit, weld, or burn. A bad contactor is a leading cause of an outdoor unit that buzzes but will not start, hard-starts, or short-cycles, and it can damage the compressor if ignored.

Compatibility

This contactor is the factory-specified switch for the Tempstar T4A624GKA200 heat pump condensing unit. The 1172472 is shared across many ICP-family outdoor units (Tempstar, Heil, Comfortmaker); confirm your unit requires a single-pole 30A contactor with a 24V coil before installing.

Installation Guide

Safety First – Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor with a multimeter.
Access – Remove the unit's electrical service panel.
Document – Photograph all line and low-voltage wiring before disconnecting anything.
Remove – Unscrew the contactor mounting screws and transfer wires one at a time, or label and remove all leads.
Install – Mount the new contactor, reconnect line and 24V coil leads exactly per your photo, and verify shunt placement.
Test – Restore power and confirm the contactor pulls in and the compressor and fan start on a cooling call.
