What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H360GKD300 — OEM Condenser | 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 T4H360GKD300 — OEM Condenser | 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 a genuine OEM 40-amp definite purpose contactor (part number 1176763) for the Tempstar T4H360GKD300 heat pump. The contactor is the high-voltage relay that the thermostat energizes through the 24V control circuit to power the compressor and outdoor fan motor. Its contacts carry the full line-voltage load every time the unit runs, so over thousands of cycles they pit, burn, weld, or chatter. A failed 40A contactor is one of the most frequent no-cool and no-heat service calls: a buzzing outdoor unit, contacts welded closed so the unit never shuts off, or contacts so corroded the compressor never starts.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and verify zero voltage with a multimeter before touching any wiring.
Access — Remove the outdoor electrical access panel to expose the contactor.
Document — Photograph every line, load, and 24V coil wire before disconnecting anything.
Remove — Transfer wires one at a time to avoid mix-ups, then unscrew the old contactor from the bracket.
Install — Mount the new 40A contactor and reconnect each wire exactly per your photo.
Test — Restore power and confirm the contactor pulls in cleanly on a call and the compressor and fan start.

Signs You Need a Replacement

Loud buzzing or chattering from the outdoor unit
