Overview
This genuine OEM high pressure switch (part number 1184656) is the high-side refrigerant safety control for the Tempstar TCA760GKA100. It continuously monitors discharge pressure and opens the low-voltage control circuit if pressure climbs to an unsafe level — protecting the compressor from catastrophic failure caused by a dirty condenser coil, a failed condenser fan, overcharge, or a blocked liquid line. When the switch trips, the unit shuts down on a high-pressure lockout. A faulty switch can either fail to open (allowing dangerous pressures) or trip nuisance cutouts that stop cooling for no real reason. Symptoms include the outdoor unit cycling off on hot days, a system that won't run after a high-pressure event, or cooling that quits intermittently. Installing a fresh OEM switch restores accurate, reliable high-side protection.

Compatibility
Designed as the direct factory replacement for the Tempstar TCA760GKA100 condenser. The same high pressure switch is used across matching ICP, Heil, and Comfortmaker condensing units that share this refrigerant platform. Verify the pressure trip rating and fitting style against your original before installing.
Installation Guide
- Safety First — Disconnect power and verify zero voltage with a multimeter before touching any wiring.
- Access — Remove the service panel to reach the refrigerant lines and control board.
- Document — Photograph the wire routing and switch location before removal.
- Remove — Disconnect the two control leads and unthread the switch from its Schrader-style port (the port seals automatically; no recovery needed on most units).
- Install — Thread on the new switch, reconnect the leads per your photo.
- Test — Restore power, run a cooling cycle, and confirm the unit operates without nuisance high-pressure trips.
Signs You Need a Replacement
- Outdoor unit repeatedly trips off on high-pressure lockout.
- System won't restart after an overpressure event.
- Intermittent cooling that resolves after a reset.
- Switch fails a continuity test at normal pressure.
