What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H560GKA100 — 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 T4H560GKA100 — 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

The Tempstar 1172786 contactor is a 2-pole, 40-amp electrical switch with a 24V control coil that powers the compressor and condenser fan motor in the T4H560GKA100. When the thermostat calls for cooling or heating, the 24V coil pulls the contacts closed, sending line voltage to the compressor. Contactors are high-wear components: their silver contacts pit and burn over thousands of cycles, and ants or debris frequently jam the armature. A failed contactor causes a no-start condition, chattering, or contacts that weld shut and won't let the unit turn off. This genuine 40A, 2-pole OEM replacement matches the original's ratings and footprint exactly.
