The oven door needs room to open and cookware must be handled safely. A narrow gap may also prevent the access required for some repairs.
What the observation means
Measure only accessible spaces without moving the cooker. A door that opens enough for a small tray may still leave inadequate working room for a particular service task.
A useful next step
Give the team the layout before the appointment and clear movable stools or loose items. Do not remove a cooker door yourself solely to create access. Fixed furniture alterations require their own decision rather than being assumed part of an appliance repair.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
