OEM Carrier Discharge Gas Thermostat HN68GA242 for Model 06CCCY899

This is the genuine OEM Factory Authorized Parts discharge gas thermostat for the Carrier 06CCCY899 Carlyle reciprocating compressor. The discharge gas thermostat continuously monitors compressor discharge line temperature and cuts out the compressor if dangerously high temperatures are detected — protecting the compressor from catastrophic overheating damage caused by refrigerant loss, liquid slugging, or restricted airflow. A failed or nuisance-tripping discharge thermostat will cause the compressor to lock out on high discharge temperature faults, leading to a no-cooling condition even when refrigerant charge and system pressures appear normal.

• Part Number & Type: OEM Carrier HN68GA242 | Discharge Gas Thermostat | Carlyle Compressor Series | Factory Authorized Parts
• OEM vs Generic: OEM thermostats are calibrated to exact factory cutout and reset temperature thresholds. Aftermarket units may use imprecise bimetal or capillary calibration, causing nuisance trips or — more dangerously — failing to protect the compressor at true over-temperature conditions.
• Install Difficulty: 3/5 — Requires refrigerant system lockout/tagout, discharge line access, and proper torque on sensor mounting hardware. Tools needed: refrigerant manifold gauges, pipe wrenches, torque wrench, and a multimeter to verify cutout continuity before restart. Recommend a qualified HVAC-R technician for this repair.
• Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.
