Error codeF7 E9
ApplianceMicrowave
First, check the vent door
The upper vent door has to open and close without anything holding it. Trim, cabinetry or other objects in its path could let the microwave overheat, so clear the way before anything else.
Reset the power
Switch off the breaker that feeds the microwave and leave it off for a full minute.
Switch the breaker back on so the unit powers up again.
Keep an eye on the display for the next minute and see whether F7 E9 shows up once more.
Run the microwave to confirm it works.
