Cabinet makes a gurgling or hissing sound even when compressor is off

Safety: No repair is usually required; do not attempt to open the sealed system.

Steps:

• Identify if normal: Light gurgling or hissing for a few minutes after the compressor stops is typically normal for Transtherm sealed systems.
• Reduce transmission: Ensure refrigerant lines are not touching the cabinet walls directly. If accessible, gently reposition or pad lines with foam to reduce noise transmission.
• Secure clips: Tighten any loose line clamps or brackets.

Note: Only if noise is extremely loud or accompanied by loss of cooling should a sealed-system technician be called.
