Our whirlpool OTR microwave MH7110XBQ shuts down. The item being heated gets very hot very quickly, and there is no "fan" noise when the microwave oven is on. You can hear the microwave tube operating, but it seems like the fan that circulates the microwave/heat is nonfunctioning.
We were able to tap on the keyboard, which would restart the "fan" noise,as if there was a loose connection behind the keypad, but now the oven just hums and the microwave shuts down after a few moments.
All other functions: clock, light, exhaust fan, etc work normally.
Can this be easily repaired, or should we start shopping for a replacement?
