What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H442GKD200 — 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 single-pole definite purpose contactor (part number 1172472) is the electromechanical switch that energizes the compressor and condenser fan in your Tempstar T4H442GKD200 heat pump. Rated at 30 amps with a 24-volt control coil and an integrated shunt, it closes when the thermostat calls for cooling, sending line voltage to the outdoor unit. Contactors endure thousands of high-current switching cycles, so the contacts eventually pit, burn, or weld. A failing contactor causes a unit that won't start, an outdoor fan and compressor that won't shut off, chattering or buzzing at the contactor, or a burnt-electrical smell from the control box. Replacing it restores clean, reliable switching and protects downstream components.

Compatibility

Engineered for the Tempstar T4H442GKD200 and shared across many ICP-family condensing units, including Heil, Comfortmaker, Arcoaire, and Day & Night models that use the 1172472 contactor. Always confirm the contactor in your unit is a single-pole, 30A, 24V-coil device before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condenser service panel to expose the control box.
Document — Photograph all wire connections before disconnecting anything.
Remove — Note line, load, and 24V coil wire positions, then transfer one wire at a time to the new contactor, or remove the mounting screws and swap the unit.
Install — Mount the new 1172472 contactor and reconnect each wire exactly per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor and fan start.
