Frididaire Complaint - Over the Oven Microwave mounting bolts inadequate
I uninstalled my 6 year old Whirlpool over the oven microwave and replaced it with a Frigidaire Professional Series Stainless Steel Microwave made in Taiwan. The mounting bolts for the Whirlpool were twice the size of the Frigidaire bolts and the mounting on the microwave was a heavy duty nut mounted in the top of the microwave unit. The Frigidaire has no mounting nuts just tiny thin metal with a couple threads tapped into it. These of course stripped when mounting the 60 lb Microwave up to the bottom of the cabinets. In addition the Whirlpool had a heavy duty mounting plate the full size of the back of the unit that mounted on the wall behind the microwave. The Frigidaire has a small 3" bracket that runs the length of the unit.
I had to fabricate two brackets to support the front of the unit to the existing cabinets. If this is the Professional series what is the lesser series like?
