OEM Carrier Discharge Gas Thermostat — HN68GA242 for Model 06CCCY550

This OEM discharge gas thermostat (part number HN68GA242) is the factory-specified replacement for the Carrier 06CCCY550 Carlyle semi-hermetic compressor. The discharge gas thermostat monitors the temperature of the hot refrigerant gas leaving the compressor. When discharge temperatures reach the unsafe threshold of 295°F, the sensor opens, signaling the system to shut down the compressor before catastrophic overheating damage can occur. Common failure symptoms include nuisance high-discharge-temperature lockouts, compressor short-cycling, or the system running normally but failing to protect against true overtemperature events — a serious reliability and safety risk in commercial refrigeration and chiller applications.

• Specs: Opening temperature: 295°F (146°C) | Type: Thermo-magnetic thermal sensor (normally closed, opens on high temp) | OEM Part #: HN68GA242 | Fits: Carrier / Carlyle 06C and 06E series semi-hermetic compressors including model 06CCCY550
• OEM vs Generic: This is a genuine OEM Carrier/Carlyle component, calibrated to the exact 295°F trip point specified for the 06CC compressor family. Off-brand substitutes often carry wider tolerance bands, risking either nuisance trips or — more dangerously — failure to open at the correct temperature, allowing compressor damage.
• Install difficulty: 3/5 — Requires system pump-down and refrigerant isolation before accessing the compressor discharge port. Tools needed: refrigerant recovery equipment, manifold gauges, appropriate wrenches, leak detector, and a torque spec reference for your compressor model. Recommended for qualified HVAC-R technicians only.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock orders ship same business day from our warehouse.

Compatibility: Designed for the Carrier 06CCCY550 Carlyle semi-hermetic compressor and the broader 06C/06E compressor series. Always verify the OEM part number on your existing sensor and cross-reference with your unit's data plate or service manual before ordering.
