Wolf Normal Refrigerant Flow Noise (Perceived Fault)

Unit makes a gurgling or hissing sound periodically.

Possible Causes

Refrigerant flowing through capillary tube and evaporator, Expansion and contraction of tubing

Safety: No disassembly is required.

Understand normal operation: Light gurgling, hissing, or whooshing sounds are typically normal as refrigerant circulates.
Verify performance: If temperatures are stable and no error codes are present, these sounds are usually not a fault.
Reduce resonance: Ensure the unit is level and not in direct contact with cabinetry that can amplify noise.
