What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TNLS2035H — 2-Pole 30A Furnas 230V | 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 TNLS2035H — 2-Pole 30A Furnas 230V | 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 OEM definite-purpose contactor set (part 51307868800, Furnas-style 230V) is the power-switching relay for the compressor and condenser fan in your Tempstar TNLS2035H unit. A 24-volt signal from the thermostat energizes the coil, closing the 2-pole, 30-amp contacts to feed 230V line voltage to the high-draw components. It is one of the most failure-prone parts in an outdoor unit because the contacts arc every cycle. Worn contacts cause hard starts, a humming unit that won't engage, intermittent cooling, or — when welded shut — a compressor that runs continuously and overheats.
