What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H460GKB200 — 24V Coil | 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 T4H460GKB200 — 24V Coil | 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 genuine OEM 2-pole, 40-amp definite-purpose contactor (OEM 1172786, CONTACTOR 2P 40A 24V) is the high-current switch that powers the compressor and condenser fan in the Tempstar T4H460GKB200 heat pump. A 24V signal from the thermostat and control board energizes the coil, pulling the contacts closed to send line voltage to the compressor. Over time the contacts pit, arc, and weld from the constant high-current switching, while the coil can burn open. A failing contactor shows up as a unit that hums but won't start, buzzing or chattering at the contactor, or a compressor that runs continuously because the contacts are welded shut.
