What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TSH448GKA101 — 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 TSH448GKA101 — 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 OEM single-pole definite-purpose contactor (Part No. 1172472) is the electrical switch that powers the compressor and condenser fan on your Tempstar TSH448GKA101 heat pump. When the thermostat calls for cooling or heating, the 24-volt control circuit energizes the contactor coil, pulling the contacts closed and sending line voltage to the compressor. Rated at 30 amps with a 24V coil and an integrated shunt, it is built to handle the high inrush current of compressor startup. Common failure symptoms include a system that won't start, chattering or buzzing at the contactor, pitted or welded contacts, and a compressor that hums but won't run. Because the contacts arc every cycle, this is one of the most frequently replaced parts in any condensing unit.
