OEM Carrier Discharge Gas Thermostat HN68GA242 / HN68GA295 for Compressor Model 06E266566

This OEM discharge gas thermostat is the factory-specified replacement for the Carrier / Carlyle compressor model 06E266566. Mounted directly on the compressor discharge line or housing, this thermostat continuously monitors the temperature of high-pressure refrigerant gas leaving the compressor. If discharge gas temperatures climb into the danger zone, the thermostat triggers a safety shutdown — protecting the compressor from catastrophic valve damage, oil breakdown, and seized bearings. Failure symptoms include nuisance high-discharge-temperature lockouts, erratic safety trips, or compressor shutdowns that cannot be traced to refrigerant charge or load issues.

• OEM Part Numbers: HN68GA242 (primary) | HN68GA295 (superseding/alternate) — both are Factory Authorized Parts for Carrier / Carlyle commercial reciprocating compressors
• Function & Protection: Monitors discharge gas temperature; opens the safety circuit on over-temperature condition to prevent compressor burnout, refrigerant oil carbonization, and thermal valve damage
• Install Difficulty: 3/5 — Requires recovering refrigerant charge before accessing the discharge line fitting. Tools needed: refrigerant recovery unit, torque wrench, manifold gauge set, leak detector. Always verify system is fully de-pressurized and de-energized before removing the old thermostat. Re-check for leaks before recharging.
• Warranty: 1-year OEM factory warranty on parts. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Engineered exclusively for the Carrier / Carlyle 06E266566 commercial reciprocating compressor platform. Cross-reference both OEM part numbers HN68GA242 and HN68GA295 against your compressor's data plate before ordering — these are direct superseding numbers within the same Carrier Factory Authorized Parts program. This is a commercial-grade, application-critical safety component; always confirm fitment with your unit's service documentation. Have questions?
