What amp contactor do I need for my Tempstar system?

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 OEM 2-pole, 40-amp definite purpose contactor (part #1059574) for the Tempstar TCH460AKA3 heat pump condensing unit. The contactor is an electrically controlled switch that uses a 24-volt thermostat signal to close its 40A line-voltage contacts, energizing the compressor and condenser fan motor. When the call ends, the 24V coil de-energizes and a spring opens the contacts to shut the unit down. Because it cycles on every run, the contactor is among the most common wear items in outdoor HVAC equipment. Typical failure symptoms include pitted or welded contacts (unit won't shut off), a buzzing or chattering coil, a burnt or melted housing, and a compressor that won't start despite a thermostat call.
