Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care MECH-05 Error Fix: Door Gasket Not Sealing

Error code MECH-05 on the Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care means: Door Gasket Not Sealing. The door gasket (rubber seal) is not creating an airtight seal — warm humid air enters the compartment, causing the compressor to run excessively and frost/condensation to form inside; diagnostic test: close the door on a dollar bill and try to slide it out — if it slides easily without resistance, the seal is weak at that point; test at multiple points around the door perimeter; clean the gasket with warm soapy water; if the gasket is deformed from age, try warming with a hair dryer to help it regain shape; replace if torn, cracked, or permanently compressed; on Jenn-Air built-in models, gaskets are model-specific and must match the door configuration
