What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4A836GKA200 — 24V Coil w/ Shunt | 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 T4A836GKA200 — 24V Coil w/ Shunt | 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 1-pole definite purpose contactor (part number 1172472) fits the Tempstar T4A836GKA200 condensing unit. The contactor is the high-voltage switch that energizes the compressor and condenser fan motor on every thermostat call for cooling. Rated at 30 amps with a 24-volt coil and a built-in shunt, it cycles the line circuit on and off thousands of times per cooling season. Telltale failure signs are a unit that hums but will not start, chattering at the contactor, pitted or welded contacts that prevent the system from shutting off, or scorched terminals from arcing.
