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 contactor (part number 51307868500) is the 4-pole, 20 amp, 115V-coil switching relay for the Tempstar TDLS1211C heat pump. The contactor is the electrically controlled switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling or heat-pump operation. Its silver-alloy contacts close to pass line voltage and open to cut it. Over thousands of cycles the contacts pit, burn, and weld, while the 115V coil can fail open. Symptoms include a unit that won't start, chattering or buzzing at the contactor, contacts that stick closed so the compressor never shuts off, or visible arcing and burnt terminals. Installing the factory-spec 4-pole 20A contactor restores clean, reliable switching.
