A True 851138 Capillary Tube regulates refrigerant circulation to maintain stable temperatures and responsive cooling across a wide range of cold-side units.
The True 851138 Capillary Tube supports refrigeration-system functions involved in refrigerant compression, expansion, heat exchange, defrost or control. Its role within the system helps contribute to proper refrigeration operation.
The True 851138 Capillary Tube might be wearing out if the unit is not cooling properly, runs warm or cannot maintain temperature. Potential operational signs might include the unit not working or blowing hot air when the tube is restricted or clogged, which may be addressed by installing a real OEM part to support reliable operation.
