Miele Microwave repair and service in New York

This is usually normal. Miele high-end microwaves and Speed Ovens have a "Cooling Fan" logic. It continues to run to cool down the magnetron and electronics even after the cooking cycle finishes to prevent overheating. It should shut off automatically after a few minutes.

Miele microwaves use a triple-safety interlock system. If the door hooks or the alignment are slightly off, the sensor won't read "closed." Try pushing firmly on the door latch area. If the error persists, one of the three micro-switches inside the door mechanism likely needs replacement.

Only use the wire racks provided by Miele that are specifically designed for that model. Standard metal or aluminum foil can cause severe arcing (sparks) and damage the interior glass or the magnetron. Always remove metal shelves when using pure "Microwave" mode unless the manual states otherwise.

Not necessarily. In Miele units, this can also be caused by a failed high-voltage diode or a blown internal safety fuse. We test the high-voltage capacitor and diode first, as these are more affordable repairs than replacing the entire magnetron.

F38 is a specific technical fault indicating a problem with the microwave's electronic power unit (inverter). This is not something a user can fix by resetting. It requires a technician to test the inverter board and potentially replace the power module to restore heating functions.
