What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A348GKA200 — 1-Pole 30A 24V 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 1-pole definite purpose contactor (part number 1172472) is the electrical switch that powers the compressor and condenser fan in your Tempstar T2A348GKA200 air conditioning system. Rated for 30 amps with a 24V control coil and an integrated shunt, the contactor energizes whenever the thermostat calls for cooling, closing its contacts to send line voltage to the outdoor unit. Over time the contact points pit, arc, and burn from the constant make-and-break cycling. A failed contactor is one of the most common causes of a condenser that hums but won't start, a unit that won't shut off, or a system that is completely dead at the outdoor cabinet. Replacing it with a genuine OEM part restores reliable switching and protects the more expensive compressor from chatter and low-voltage damage.

Remove — Loosen the terminal screws, transfer wires off one at a time, and unscrew the old contactor from the bracket.
Install — Mount the new contactor, reconnect each wire to the matching terminal per your photo.
Test — Restore power, call for cooling, and confirm the contacts pull in and the compressor and fan start.
