OEM Carrier Discharge Gas Thermostat (HN68GA242) — 295°F Cutout for Model 06EREY166466

The Carrier HN68GA242 is the factory-specified discharge gas thermostat (thermal sensor) for the 06EREY166466 Carlyle commercial compressor. Mounted directly on the compressor discharge line, this high-limit thermostat continuously monitors discharge gas temperature and opens the control circuit when temperature exceeds 295°F — protecting the compressor from catastrophic overheating, oil breakdown, and valve damage. A failed or out-of-calibration sensor typically causes nuisance high-temperature lockouts at normal operating conditions, or — more dangerously — fails to trip when a true overtemperature event occurs, risking compressor destruction.

• Specs: Opens at 295°F (146°C) | Carlyle / Airpax design | Also referenced as OPR295, 1225, 5100034242 | Fits 06E and 06C series Carlyle compressors
• OEM vs Generic: This is a safety-critical high-limit device. OEM units are factory-calibrated to the exact 295°F setpoint. Aftermarket substitutes frequently exhibit ±10–15°F calibration drift — unacceptable on a discharge line where a few degrees can mean the difference between a protected and a destroyed compressor.
• Install difficulty: 3/5 — Requires refrigerant system pump-down before accessing the discharge line. Tools needed: manifold gauge set, adjustable wrench, Teflon tape, multimeter (continuity check post-install). Confirm polarity-free NC circuit closes at ambient before reinstalling panels.
• Warranty: 1-year OEM factory warranty against defects. Orders placed before 3 PM ship same business day from our warehouse.

Compatibility: Designed for Carrier / Carlyle model 06EREY166466 commercial reciprocating compressors and associated packaged or split commercial refrigeration systems using the 06E/06C compressor platform. Always verify the 295°F setpoint and sensor body dimensions against your existing unit's data plate before ordering. Not sure it fits?
