What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TXA248AKA1 — 1-Pole 35A 24V Coil | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

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 a genuine OEM single-pole definite purpose contactor (part number 1050839) for the Tempstar TXA248AKA1 condensing unit. The contactor is the electrically operated switch that powers up the compressor and condenser fan motor whenever the thermostat calls for cooling. Rated at 35 amps with a 24-volt control coil, it energizes when the low-voltage signal reaches the coil, pulling the contacts closed to feed line voltage to the outdoor unit. When the contactor fails, the most common symptoms are a system that will not start, chattering or buzzing at the outdoor unit, pitted or welded contacts that keep the compressor running, or visible arcing and burn marks on the terminals. Because the contacts carry high inrush current on every start, this is one of the most frequently replaced components in any air conditioner or heat pump.

Document — Photograph all wire connections before disconnecting anything.
Remove — Label and disconnect the line, load, and 24V coil wires, then unbolt the old contactor from the mounting plate.
