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 the genuine OEM single-pole 30 amp contactor with a 24V coil and integrated shunt (part number 1172472) for the Tempstar T4H424GKD200. The contactor is the high-voltage switch that energizes the compressor and outdoor fan motor. When the thermostat calls for cooling or heat-pump operation, the 24V control signal pulls in the contactor coil, closing the contacts and sending line voltage to the compressor. Over time the contacts pit, burn, or weld, and the coil can fail open. A worn contactor causes hard starts, chatter, or a unit that simply won't run. This rated 30A, 1-pole contactor with shunt is the correct OEM replacement.

Compatibility

Direct OEM replacement for the Tempstar T4H424GKD200 outdoor unit and shared across related ICP-family condensing units and heat pumps (Heil, Comfortmaker, and others) that use a 1-pole 30A / 24V contactor. Confirm the 30A rating, single-pole configuration, and 24V coil on your existing contactor before ordering.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter — the line side stays hot until the disconnect is pulled.
Access — Remove the outdoor unit's electrical access panel.
Document — Photograph all line, load, and 24V coil connections before disconnecting.
Remove — Transfer wires one at a time, or label them, then unscrew the old contactor from its bracket.
Install — Mount the new 30A contactor, reconnect each wire to the matching terminal per your photos, and confirm tight lugs.
Test — Restore power, call for cooling, and verify the contactor pulls in and the compressor/fan start.

Signs You Need a Replacement

Buzzing, humming, or chattering from the contactor.
Compressor and fan won't start on a cooling call.
Pitted, burned, or welded contacts.
Coil reads open — no continuity across the 24V terminals.
