The correct replacement for Tempstar model TSH548HKA100 — 24V w/Shunt OEM 1172472 | 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.

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 OEM definite-purpose contactor (part #1172472) is a single-pole, 30-amp unit with a 24-volt coil and integrated shunt, built for the Tempstar TSH548HKA100 condensing unit. The contactor is the high-current switch that energizes the compressor and condenser fan motor whenever the thermostat calls for cooling. The 24V control coil pulls in the contacts, while the shunt provides the additional terminal path required by this platform's wiring. Contactors are one of the most common HVAC failure points: their contacts pit, burn, and weld over thousands of switching cycles. A failed contactor causes no cooling, a buzzing or chattering condenser, or a compressor that runs continuously and won't shut off because the contacts have welded closed.

Installation Guide

Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage across the contactor terminals with a multimeter.
Access — Remove the condenser service panel to reach the contactor and control wiring.
Document — Photograph every line, load, and 24V coil wire before disconnecting.
Remove — Transfer wires one at a time, or unscrew the contactor from its mounting bracket and label leads as you go.
Install — Mount the new contactor, then reconnect line, load, and coil wires exactly per your photo.
Test — Restore power, call for cooling, and confirm the contactor pulls in cleanly with no chatter and the compressor and fan energize.
