Whirlpool WOC54EC7HB 5.7 cu.ft. Black Smart Combination Wall Oven

This unit was just installed in my kitchen a week or so ago. The microwave will not get past open and shut door on the screen. I've followed all the instructions exactly as in the manual. Very disturbing...

Bought this along with three other Whirlpool appliances, replaced old ones in our lake house. The home these appliances are installed is not our primary residence so they don't get used daily. February 2020, new appliances installed. From the get go our oven combo didn't work, error read issue with cooling fan so it would shut down automatically. Replacement sent out, installed and works fine now. When I use broil it smells like plastic burning, used broil three times and still smells. Microwave design needs to be changed, it closes fine but you have to give it an extra push in order for the inside light to turn off and microwave operational. Repair guy sent out, he said we'd have to live with it. So every single time we use the microwave we have to close it and give it a push in in order to use it. Yes, annoying because this unit was pricey and now we have to take extra precautions that it's closed. Sometimes the light will come on when you walk by it, have to push the door in again to make sure it's closed. You'll walk by and see the light on inside....very frustrated after spending all this money.
