What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A360GKD100 — OEM 1172786 | 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, 24-volt contactor (part number 1172786) for the Tempstar T2A360GKD100 condensing unit. The contactor is the electrical switch that energizes the compressor and condenser fan when the thermostat calls for cooling; its 24V coil is pulled in by the low-voltage control circuit. Pitted, welded, or chattering contacts cause hard starts, no-cool conditions, or a unit that won't shut off. This factory-rated contactor restores clean, reliable switching.
