Condensation between door glasses - Microwave Ovens

There is a small vent hole at the bottom of your oven door that is made to allow you to reach a brush up to clean the glass.. It sounds like your stove seal isn't sealing.

Condensation inside the oven comes mainly when the temperature is below 100 Celsius, and this phenomenon is evident in almost all manufacturers. That means, the condensation starts at the beginning and at end of baking. My advice is the same as many manufacturers recommend: Before baking, preheat the oven to min. 100 Celsius and after that place the food in the oven. Reverse the procedure in the "cool down" phase before the temperature drops below 100 ° C and remove the food from the oven.
After that condensation should be drastically reduced.
Condensation could be technically solved but it would be too expensive for manufacturers (more parts inside oven) as well as for customers also (too expensive appliance and lost energy).

PS. This applies to the traditional way of baking

Air from inside the oven is getting by the seals around the inside glass and condensing on the cooler outside glass layer.

Sounds like you need to call them back, they should warranty their work. Make them do it until ti is right. Make him show you it doesnt steam up before he leaves. OR Dont pay them and dont sign off that it is fixed.

That is normally caused by the clear plastic adhesive cover either having been removed or missing. It covers the perforated door inner and stops condensation and food particles from getting inside the door cavity where is cannot be cleaned.

Your glass seal has failed and I doubt it makes sense to replace the door. Yes, it can be dangerous as the moisture becomes worse you risk the chance the glass could over-heat and blow out. Sounds like you need to replace it, sorry!

For most microwaves the process is pretty straightforward. You can open the door and you will see the screws that hold the outerinside panel on to the glass. After you remove those screws you will see the screws that hold the ouside cover to the door in place. Once you get that far you will see what is holding the glass in place. Keep in mind to replace the gaskets around the glass right and anything you take off to get to the glass itself. If you are getting condensation from range top cooking then the seal around the glass may need to be replaced. You really cannot hurt anything by taking it apart, but it needs to be put back together exactly the way you take it apart. Good luck and hope this helped.

Any water in between the glass and the door should evaporate eventually.
I wouldn't advise trying to open any seams in the door or removing the glass to get the water out as that would permanently damage your microwave.

Your models manual talks about steam/water condensation that gets trapped between the door and the glass and what to expect:
