Whirlpool MW Cooling Fan Motor Slow

After prolonged non-use (a month or longer), I don’t hear what I think is the magnetron cooling fan running. After a week or so of regular use, I can hear the fan. In order to confirm what’s happening (I think a sticky armature), I need to gain acces to the fan motor. The MW is mounted on the wall in between and below kitchen cabinets. Can I access this motor from underneath, or do I have to remove the unit from the wall altogether?
Thanks for any input!!

The microwave will need to come off the wall so you can get to the motor to clean it up. That may be all it takes to get it working again and possibly prevent another problem in the future.

Thanks Brian…I was afraid of that. Now all I need is two men and a small boy to get it off the wall.

Good luck and let us know how it turns out.
