OEM Carrier Discharge Gas Thermostat HN68GA242 for Model 06EY766ARP

This OEM discharge gas thermostat is the factory-specified replacement for the Carrier 06EY766ARP Carlyle reciprocating compressor. The discharge gas thermostat monitors the temperature of refrigerant gas exiting the compressor cylinders. If discharge temperatures exceed safe operating limits — a condition that accelerates oil breakdown and causes catastrophic compressor failure — this thermostat triggers a protective shutdown. A failed or out-of-calibration discharge gas thermostat may cause nuisance trips, failure to start, or, worse, allow the compressor to run unprotected at dangerous discharge temperatures.

• Specs: OEM Carrier/Carlyle Discharge Gas Thermostat | Part# HN68GA242 | Replaces legacy Carlyle and Carrier part numbers | Factory-calibrated trip point for Carlyle compressor applications
• OEM vs Generic: The discharge gas thermostat is a precision safety device — trip-point calibration is critical. OEM units are factory-set to exact Carlyle specifications. Aftermarket alternatives may have wider tolerances, risking either nuisance shutdowns or inadequate compressor protection.
• Install difficulty: 3/5 — Requires recovery of refrigerant charge per EPA Section 608 before accessing the compressor fitting. Tools needed: refrigerant recovery machine, manifold gauge set, torque wrench, and thread sealant. Always tag out and lock out power before beginning work.
• Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed for the Carrier 06EY766ARP Carlyle semi-hermetic reciprocating compressor. Verify your compressor model and existing thermostat part number on the compressor data plate before ordering. Cross-reference numbers include Carlyle OPR295 and 5100034242. Our technical team is available to confirm fitment before you order — don't guess on a critical safety component.
