Assess the causeFollow the evidence.
Check shelf obstruction, cabinet level, hinges, alignment and the condition of the magnetic gasket.
The exact model and operating conditions determine which tests apply. These are possible inspection directions, not a list of components that must be changed.
Before the appointmentKeep the useful details.
Remove items that protrude beyond the shelf edge and show where the gap remains.
Record the timing, previous work and accessible model label. Do not remove covers or handle live, refrigerant or pressurised components to obtain information.
