General Electric Room Air Conditioner Compressor & Sealed System

This capillary tube is the refrigerant metering element used in sealed cooling circuits to regulate refrigerant flow into the evaporator. Replacing a damaged or clogged tube helps restore proper cooling balance and system efficiency. What it does

• Meters refrigerant flow from the high-pressure side into the evaporator coil for controlled evaporation.
• Helps maintain consistent evaporator pressure and temperature when functioning correctly.
• Common symptoms of a failing or restricted capillary tube: reduced or inconsistent cooling, warm compartments, excessive frost buildup, or cycling issues.
• Not a compressor or control — part of the sealed refrigeration circuit; issues may mimic other sealed-system faults.

• One capillary tube

• Sealed-system service typically requires specialized tools for recovery, brazing/soldering, and pressure testing.
• Recover refrigerant before removal and follow all EPA and local regulations for refrigerant handling and disposal.
• Inspect for leaks and perform a full evacuation and recharge to OEM refrigerant specifications after installation.
