Overview
This OEM high pressure switch (part number 1184656) is the refrigerant high-side safety control for the Tempstar TCA960GKA200. It continuously monitors discharge pressure and opens the control circuit to shut the compressor down if pressure climbs to a dangerous level — protecting the compressor from catastrophic damage caused by a blocked condenser, a failed fan motor, an overcharge, or a dirty coil. The switch is normally closed and resets once pressure returns to a safe range. When this safety fails, you may see a compressor that short-cycles, a unit that locks out on high-pressure faults, or a system that refuses to start even though everything else checks out. Replacing the switch restores proper high-side protection and reliable operation.

Compatibility
A direct-fit OEM replacement for the Tempstar TCA960GKA200 condensing unit. The 1184656 high pressure switch is shared across the ICP family — Tempstar, Heil, Comfortmaker, Arcoaire, and ICP — on equivalent condenser platforms. Confirm the part number and refrigerant connection style on your existing switch before ordering.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the condenser service panel to reach the high-side line and control box.
- Document — Photograph the wire routing and switch location before disconnecting.
- Remove — Disconnect the two control wires; if the switch is a Schrader-style sensing fitting, no refrigerant recovery is needed — unthread it from the port.
- Install — Thread the new switch onto the sensing port, reconnect the control wires per your photo.
- Test — Restore power and confirm the unit starts and runs without a high-pressure lockout.
Signs You Need a Replacement
- Compressor short-cycles or trips on high-pressure faults with normal pressures.
- Unit locks out and will not restart despite a clean coil and working fan.
- Switch fails to reset after pressure normalizes.
- Open circuit reading across the switch terminals at rest.
