What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model TCA236AKA1 — 24V Coil | 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 TCA236AKA1 — 24V Coil | 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 genuine OEM single-pole contactor (part #1050699) is the electrical switch that controls power to the compressor and condenser fan motor in your Tempstar TCA236AKA1 condensing unit. Rated for 25 amps with a 24-volt control coil, it energizes when your thermostat calls for cooling, allowing line-voltage current to flow to the outdoor unit. Contactors are one of the most common HVAC failure points because their contacts arc and pit with every cycle. A failed contactor produces a humming or chattering noise, pitted or welded contacts, or a complete no-cool condition where the outdoor unit will not start even though the thermostat is calling. Replacing it with the correct OEM-spec part restores reliable switching and protects your compressor from low-voltage damage.

Compatibility

Engineered as a direct OEM replacement for the Tempstar TCA236AKA1 condensing unit. The same 1050699 contactor is also used across many ICP-family outdoor units (Tempstar, Heil, Comfortmaker, and related brands) that specify a 1-pole, 25A, 24V coil contactor. Always verify your existing contactor's amp rating, pole count, and coil voltage before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage at the contactor terminals with a multimeter before touching any wires.
Access — Remove the service/electrical access panel on the condensing unit.
Document — Take a clear photo of every wire and terminal position before disconnecting anything.
Remove — Note the line, load, and 24V coil terminal connections, then disconnect each spade and remove the mounting screws holding the old contactor.
Install — Mount the new 1050699 contactor in the same orientation and reconnect each wire exactly as photographed.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly and the compressor/fan energize without chatter.
