I was with Whirlpool Corp. for 25 years and one of my last assignments was managing the customer service end of the business in all the western states (this included service personnel, technicians). Although not technically competent myself I did accompany technicians to many customer's homes and either observed or assisted in a lot of repairs. I did have technicians who could replace an over-the-range micro by themselves but they always had some "specialized" tools they had devised. Usually this combined a perfectly sized milk crate to hold the micro and a wealth of experience. Therefore, I agree that this is 99% of the time a two-person job.

WORD OF WARNING: When removing the old unit be extremely careful to avoid the capacitor inside the control panel. These store LARGE amounts of electricity and if not properly discharged before you come in contact they may seriously injure you or can even cause death. If you know the unit needs replacement work only on the exterior. Good luck and be careful. These are NOT toys.
