That is a funny looking unit! You know we are Fixya and not Thermador right? There must be too much heat back there and it is over heating the socket and the microwave lead which isn't heat resistant and normally only has its own heat to contend with. What I would do is pull all that appliance out an put it on the other side to the kitchen, and ask a bigger electrical contractor to MOVE and REPLACE a pair of outlets in a kitchen for a remodel. What I would do is to certainly move the microwave outlet to the cupboard next door. Make a decision whether to move to 220 oven outlet as well. Don't mention anything about burning plugs or the 87 volts. Tell them you would like Industrial Quality Outlets and not domestic. I reckon that will fix the problem.

By sticky do you mean as dirty or not working properly. If the door sticks squirt a little WD40 in all the working parts like hinges and latches and try that.
