Dacor DOB30M977DS 30 in 4.8 cu ft True Convection Wall Oven with WiFi MECH-GASKET Error Fix: Oven Door Gasket Worn or Deteriorated

Error code MECH-GASKET on the Dacor DOB30M977DS 30 in 4.8 cu ft True Convection Wall Oven with WiFi means: Oven Door Gasket Worn or Deteriorated. Heat is escaping around the oven door edges, causing uneven cooking temperatures and energy waste. The door gasket (seal) is visibly cracked, torn, flattened, or has lost its shape. On Dacor ovens, the gasket typically hooks into clips around the oven cavity opening. Remove the old gasket and install a new one by pressing it into the retaining clips. Do not use the oven until the gasket is properly seated — a damaged gasket can cause a fire hazard during self-clean cycles.
