Overview
This is a genuine OEM high pressure switch (part number 1184656) for the Tempstar TCA960GKA100 condensing unit. The high pressure switch is a safety control wired into the 24V control circuit that continuously monitors refrigerant discharge pressure. If system pressure climbs above the factory cutout setpoint — typically caused by a dirty condenser coil, failed condenser fan motor, blocked airflow, or overcharge — the switch opens and shuts down the compressor to prevent catastrophic damage. When the high pressure switch fails or trips intermittently, the system short-cycles, fails to cool, or locks out entirely. Replacing it with the exact OEM part restores reliable compressor protection.

Compatibility
Engineered as a direct factory replacement for the Tempstar TCA960GKA100. The same 1184656 switch is used across many ICP-family condensers and heat pumps built by ICP/Heil under the Tempstar, Heil, Comfortmaker, and Carrier-affiliated lines. Always confirm the part number on your existing switch before ordering.
Installation Guide
- Safety First – Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter.
- Access – Remove the condenser service panel to reach the control area and refrigerant line connection.
- Document – Photograph the wire routing and terminal positions before disconnecting anything.
- Remove – Disconnect the two control leads and unthread the switch from its Schrader-style pressure port (the port is self-sealing, so no recovery is needed on most units).
- Install – Thread the new 1184656 switch onto the port, tighten snugly, and reconnect the leads per your photo.
- Test – Restore power and confirm the compressor energizes and runs without nuisance tripping.
Signs You Need a Replacement
- Compressor will not start or locks out on a safety fault
- System short-cycles or trips during hot weather
- Continuity reads open at normal idle pressure
- Switch fails to reset after pressure normalizes
