The correct replacement for Tempstar model T4A336GKA100 — 1-Pole 30A 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.

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 definite-purpose contactor (part number 1172472) is the electrical switch that energizes the compressor and condenser fan motor in your Tempstar T4A336GKA100 air conditioner. Rated for 30 amps with a single pole and a 24V control coil, it includes an integrated shunt for reliable load switching. When the thermostat calls for cooling, the 24-volt signal pulls the contactor closed, sending line voltage to the outdoor unit. A failing contactor causes hard starting, chattering or buzzing, pitted or welded contacts, and an outdoor unit that won't run even when the thermostat calls for cooling. Replacing a worn contactor is one of the most common and cost-effective HVAC repairs.

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser service panel.
Document — Photograph all wire connections before disconnecting anything.

Install — Mount the new contactor and reconnect each wire exactly per your photo, ensuring tight terminals.
Test — Restore power and confirm the contactor pulls in and the unit runs on a cooling call.
