Carrier 17400516000849 High Pressure Switch for Heat Pump Condensers

The Carrier 17400516000849 is an OEM replacement high pressure switch designed for use in heat pump condenser units. This safety component monitors refrigerant pressure on the high side of the system and interrupts the compressor circuit if pressure exceeds the safe operating threshold, protecting the compressor and other internal components from damage caused by excessive pressure conditions.

Key Features:

• OEM Carrier replacement part — ensures proper fit, function, and reliability
• Protects the compressor by shutting down the system when high-side refrigerant pressure exceeds safe limits
• Designed for heat pump condenser applications
• Direct drop-in replacement for original equipment — no modifications required
• Also cross-referenced and supplied under Heil and MrCool heat pump condenser applications

Replacing a faulty high pressure switch restores critical compressor protection and ensures the refrigeration system operates safely within design parameters. This is an essential safety control component for maintaining the long-term reliability of the heat pump system.
