What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H560GKD100 — 24V Coil Heat Pump | 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 is the genuine OEM 2-Pole, 40 Amp Contactor (part #1172786, CONTACTOR 2P 40A 24V) for the Tempstar T4H560GKD100 heat pump. The contactor is the heavy-duty relay that switches line voltage to the compressor and condenser fan motor. When the thermostat calls, the 24V coil pulls in the contactor and energizes the outdoor unit; when the call ends, it drops out. Contactors are one of the most common failure points in any condensing unit because their contacts pit, weld, or burn from constant arcing. A failed contactor can leave the unit completely dead, stuck running even after the call ends, or chattering and buzzing as the coil struggles to hold the contacts closed.

Compatibility

Direct-fit replacement for the Tempstar T4H560GKD100 heat pump and shared across many ICP-family condensing units of this size. A 2-pole 40A contactor with a 24V coil is a common spec, but always confirm OEM number 1172786 and verify your unit uses a 24V control coil before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and verify zero voltage across the line terminals with a multimeter.
Access — Remove the service panel to expose the contactor in the control box.
Document — Photograph every line, load, and 24V coil wire before disconnecting.
Remove — Move each wire from the old contactor to the new one one at a time, then unscrew the old contactor from its bracket.
Install — Mount the new contactor, confirm all line/load and 24V coil leads match your photo.
Test — Restore power and confirm the contactor pulls in on a call and drops out cleanly when satisfied.
