Overview

This is a genuine OEM high pressure switch (part number 1184656) for the Tempstar TCA948GKA200 condensing unit. The high pressure switch is a safety control wired into the 24V circuit that monitors refrigerant discharge pressure. If pressure rises above the factory cutout — commonly from a dirty condenser coil, failed condenser fan motor, restricted airflow, or an overcharge — the switch opens and de-energizes the compressor to prevent damage. A failing or intermittently tripping switch causes short-cycling, no cooling, or a full safety lockout. Installing the exact OEM replacement restores dependable high-side protection.
