Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care MECH-08 Error Fix: Dirty Condenser Coils

Error code MECH-08 on the Jenn-Air JB36NXFXLE 36 in Built-In French Door Refrigerator with Preserva Food Care means: Dirty Condenser Coils. The condenser coils are covered with dust, pet hair, lint, and debris — this is the single most overlooked refrigerator maintenance item and the leading cause of reduced cooling efficiency and premature compressor failure; on Jenn-Air built-in refrigerators, the condenser is typically behind the front toe-kick grille at the bottom; remove the grille and use a condenser coil brush (long, thin brush designed for this purpose) followed by a vacuum to clean the coils; service every 6-12 months; in homes with multiple pets, every 3 months is recommended
