What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T2A336GKB100 — 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. You can verify this by checking the data plate on your Tempstar equipment which lists the model number T2A336GKB100 — 1-Pole 30A 24V 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 is a genuine OEM single-pole definite-purpose contactor (Tempstar part #1172472) for the Tempstar T2A336GKB100 condensing unit. Rated at 30 amps with a 24-volt control coil and an integrated shunt, this contactor is the electrical switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V coil magnetically pulls the line-voltage contacts closed to power the outdoor unit. Each cycle closes the contacts under high inrush current, so they slowly pit, burn, and can weld — making the contactor a leading cause of a unit that hums without starting, chatters, or refuses to shut off. This affordable OEM replacement restores reliable, full-power switching.

Compatibility

This contactor is the factory-specified replacement for the Tempstar T2A336GKB100 air conditioner / heat pump condensing unit. As an ICP-family part (Tempstar, Heil, Comfortmaker, and related brands share componentry), it also services many comparable outdoor units originally equipped with a 30A single-pole, 24V-coil contactor. Confirm your existing contactor's amp rating, pole count, and coil voltage against the specs above before installing.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker. Verify zero voltage at the contactor terminals with a multimeter before touching anything.
Access — Remove the electrical service panel on the condensing unit to expose the contactor.
Document — Photograph every wire and terminal location before disconnecting. Note line, load, and coil connections.
Remove — Transfer wires one at a time to the new contactor, or label and remove them, then unscrew the old contactor from its bracket.
Install — Mount the new contactor, reconnect all line, load, and 24V coil wires exactly per your photo. Confirm tight terminal screws.
Test — Restore power and call for cooling. Confirm the contacts pull in cleanly and the compressor and fan start without chatter.

Signs You Need a Replacement

Burned, pitted, or welded contact points (unit won't shut off).

My AC clicks but the compressor won’t turn on. What’s wrong?

Clicking from the outdoor unit without the compressor starting = worn contactor. The contactor sends power to the compressor. When its contacts are pitted, it clicks but can’t make solid contact. Look for: visible pitting/burn marks on the contactor face, intermittent operation, or buzzing.

Is this contactor compatible with Bryant or Payne too?

The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Tempstar contactor?
