Hoover Overheating Door / Insufficient Ventilation

Microwave door glass or outer surface becomes excessively hot to the touch during normal microwave-only operation.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Blocked ventilation grills, Faulty cooling fan, Long high-power cycles without rest, Damaged door glass or inner panel

User-level checks:

Ensure all vents are clear and that the microwave has the recommended clearance from walls and cabinets.
Avoid running multiple long, high-power cycles back-to-back; allow cooling periods.
Check for damage to the door glass or inner panel; if cracked, stop using the microwave.

Next steps:

If the door remains excessively hot despite good ventilation, the cooling system or door assembly may be faulty and should be inspected by a technician.
