Whirlpool MT4070SK 700 Watts Microwave Oven Questions & Answers
In most cases this is due to a broken door opening lever or loose or broken door latch / hook parts.
They can only be accessed and examined if the cover is removed from the microwave.
In many over the range models, you can access the door parts by removing the control panel assembly.
Sometimes you may be able to get it open by pushing up gently on the bottom of the door while pushing the button, in case you need to empty it.

The button assembly or the arm thats attached to the push button is broken. With the unit unplugged. Carfully take off the screws from the sides and around the back of the unit around the outside of the cover. Now once apart, DO NOT TOUCH any electrical parts. Look at the mechanism and see if you can see why the buttons not activating an arm to trigger the door latch. If you think you see why, Go to http://www.repairclinic.com and enter your model #.. Answer the questions and then a bunch of parts will come up. If they dont then get the tele # from there and call them. Depending on how old the oven is, you may want to consider a newer oven??. Good luck

I think compared to the replacement cost of the complete combo you will find the microwave repair cost reasonable.
Unless additional ventilation is provided to the rear and sides of your built in combo, a lack of circulating cooling air could have been at least part of the reason why your microwave failed - the electronics need lots of air circulation.
You might want to address this while the unit is removed for repair.
The voltages inside a microwave are potentially lethal and so the checking and repair is a specialised task...
