Overview
This genuine OEM high pressure switch (part number 1184656) is a refrigerant-side safety control on the Tempstar TCA760GKB101 condensing unit. It monitors discharge-line pressure and opens the control circuit to shut down the compressor whenever pressure rises to an unsafe level — protecting the compressor and refrigerant system from damage caused by a dirty condenser coil, a failed condenser fan, an overcharge, or restricted airflow. A faulty switch can either nuisance-trip and stop cooling when pressures are actually normal, or fail to open and leave the compressor unprotected. Common symptoms are an outdoor unit that short-cycles, a compressor that trips out on hot days, and a no-cooling call that clears after the unit cools down.

Compatibility
Direct OEM replacement for the Tempstar TCA760GKB101 air conditioning condenser. Confirm the cut-out/cut-in pressure setpoints and fitting/connector style match your original switch before installing.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the service panel to reach the switch on the high-pressure refrigerant line.
- Document — Photograph the wiring and switch location before disconnecting.
- Remove — Disconnect the leads and unthread the old switch from its Schrader-style port (the port self-seals, so no recovery is needed on most units).
- Install — Thread on the new switch, snug it to spec, and reconnect the leads per your photo.
- Test — Restore power, call for cooling, and confirm the compressor runs without nuisance tripping.
