Observe before changing anything
ReversibleNote the selected mode, door position and whether cycling matches heating-element operation.
Isolate the failing boundary
ReversibleCompare behavior with the model manual and run a brief empty convection test after full preheat.
Apply the narrow correction
ReversibleRemove only loose foil or cookware blocking user-accessible vents.
Verify the result and stop at the boundary
ReversibleService is appropriate for scraping, stalled fan, smoke or a temperature problem.
