What amp contactor do I need for my Tempstar system?

The correct replacement for Tempstar model T4H348GKA200 — 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 T4H348GKA200 — 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 is the genuine OEM 1-pole 30-amp contactor with shunt (part number 1172472) for the Tempstar T4H348GKA200 heat pump. The contactor is the high-voltage relay that powers the compressor and condenser fan motor. When the thermostat calls and the control board energizes the 24V coil, the contactor pulls in and closes the line-voltage contacts. Over time the contacts pit and burn from arcing, the coil can fail open, or the points can weld closed — all common causes of a unit that hums but won't start, a condenser that runs nonstop, or chattering at the contactor. The integrated shunt provides the factory-correct circuit path for this model.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter across the line terminals.
Access — Remove the condensing unit service panel to reach the control box and contactor.
Document — Photograph every line, load, and 24V coil wire before disconnecting.
Remove — Transfer wires one at a time, or pull the old contactor from its mounting and move the leads to the new unit, matching terminal positions exactly.
Install — Mount the new 1172472, reconnect line, load, and 24V coil leads per your photo, and confirm all terminals are tight.
Test — Restore power and verify the contactor pulls in on a cooling/heating call and the compressor and fan energize.
