What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H360GKD400 — Condenser Switching | 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 T4H360GKD400 — Condenser Switching | 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 OEM 40-amp definite purpose contactor (part 1176763) is the main power switching relay for the Tempstar T4H360GKD400 condensing unit. On a thermostat cooling call, the low-voltage coil energizes and pulls the contacts closed, delivering line voltage to the compressor and condenser fan motor. Rated at 40 amps, it handles the higher inrush and run current of this larger condenser. Contactors are among the highest-wear components in any outdoor unit — repeated arcing pits and burns the contacts until they either fail to make contact (no cooling) or weld shut (compressor won't stop). Replacing a worn contactor before it welds prevents downstream compressor and capacitor damage.
