OEM Carrier Discharge Gas Thermostat 295°F — Model 07ED044521 (HN68GA295)

The Carrier HN68GA295 is a Factory Authorized Parts™ discharge gas thermostat (also called a discharge line thermostat or DGT) designed for Carrier commercial chiller and compressor applications, including the 07ED044521. This thermostat monitors refrigerant discharge gas temperature leaving the compressor and opens the control circuit at 295°F to protect the compressor from catastrophic overheating. When this part fails or trips without reset, you'll typically experience nuisance high-temperature lockouts, compressor shutdowns shortly after startup, or a system that refuses to restart even after a manual reset attempt. Confirming a faulty discharge gas thermostat (versus an actual high-discharge condition) with a calibrated thermocouple before replacement is strongly recommended.

• Specs: Trip/open temperature: 295°F | Factory Authorized Parts™ OEM designation | Proprietary design specifications — not replicated by aftermarket manufacturers | Lead wire included
• OEM vs Generic: The HN68GA295 carries proprietary design tolerances that are not available to third-party parts makers. Generic substitutes risk inaccurate trip points, which can either fail to protect the compressor or cause premature nuisance shutdowns — both costly outcomes on commercial equipment.
• Install difficulty: 3/5 — Requires refrigerant system lockout/tagout and relief of system pressure before access. Tools needed: refrigerant recovery equipment, torque wrench, electrical multimeter, and wire connectors. Recommended for certified HVAC/R technicians only.
• Warranty: 1-year OEM factory warranty. Preserves existing equipment warranty and maintains agency listings and safety standards. Ships same business day from our warehouse.
