I am struggling to remove an old Whirlpool over the counter microwave ovne. I have disconnected the vent hood, removed all the plastic grill fronts, have turned the 'quick release' bolts and they are floating freely but the unit does not 'rotate forward.' Pulling on the unit I do see the vertical brackets that the quick release bolts pass through and they float a little. But something else is still holding the unit to the wall. One past posting said something about a back up safety system but I don't see one. The instructions for the quick release bolts states to 'SUPPORT OVEN BEFORE TURNING' implying that the oven will be released and fall forward. BUT IT DOESN'T! Help!!:sad:
