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 is a genuine OEM single-pole definite purpose contactor (OEM part #1172472) for the Tempstar T4A436GKD200 air conditioning condenser. The contactor is the electrically operated switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. Rated at 30 amps with a 24-volt control coil and equipped with an integrated shunt, it carries the high-voltage load to the compressor while being safely controlled by the low-voltage thermostat circuit. A failing contactor is one of the most common causes of an outdoor unit that will not start: pitted, burned, or welded contacts prevent the compressor from receiving power, while chattering or buzzing points to a weak or failed 24V coil. Replacing it restores reliable, clean switching and protects the more expensive compressor downstream.

Compatibility

Engineered as a direct-fit replacement for the Tempstar T4A436GKD200 condensing unit.

Always confirm against the data plate or your unit's parts list before ordering.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and the breaker, then verify zero voltage at the contactor terminals with a multimeter.
Access — Remove the condenser service panel to expose the control box.
Document — Photograph all line, load, and 24V coil wires before disconnecting anything.
Remove — Note wire positions, disconnect the high-voltage line/load leads and the two 24V coil leads, then unscrew the old contactor from the mounting bracket.
Install — Mount the new contactor and reconnect every wire exactly per your photo, confirming the coil leads land on the 24V terminals.
Test — Restore power, call for cooling, and verify the contactor pulls in cleanly and the compressor and fan start.

Signs You Need a Replacement

Outdoor unit hums but the compressor and fan never start.
Loud chattering or buzzing from the contactor when cooling is called.
Visibly pitted, burned, or melted contact points.
Contacts stuck closed — the unit runs continuously and will not 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?

Should I use OEM or aftermarket for my Tempstar contactor?
