Overview
This is a genuine OEM high pressure switch (part number 1184656) for the Tempstar TCA924GKA200 condensing unit. The high pressure switch is a safety control wired into the 24V control circuit that monitors refrigerant discharge pressure. When system pressure exceeds the factory trip point — commonly from a dirty condenser coil, a failing condenser fan motor, overcharge, or blocked airflow — the switch opens and de-energizes the compressor to prevent compressor and line damage. A failed or tripped switch presents as a compressor that won't run, repeated high-pressure lockouts, or loss of cooling on the hottest days when head pressure peaks.

Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the condenser service/control panel to expose the switch and refrigerant line tap.
- Document — Photograph the two wire leads and routing before disconnecting.
- Remove — Unplug the spade terminals, then unthread the switch from the self-sealing Schrader-style fitting.
- Install — Thread on the new switch hand-tight plus a quarter turn, reconnect both leads per your photo.
- Test — Restore power and verify the compressor energizes and runs without tripping on high pressure.
Signs You Need a Replacement
- Compressor will not start while the fan still runs
- Unit repeatedly short-cycles or locks out on a high-pressure fault
- No cooling on the hottest part of the day when head pressure peaks
- Continuity reads open across the switch at normal idle pressure
