this microwave traps moisture between glass on door. i placed a service call and was told it was normal and would evaporate. yes, it does. my kitchen aide mixer which sits behind the microwave drips with moisture after i use the microwave. the door also sticks and will not pop open;  i have to grab the right hand corner and pull the door open. the unit is very loud and the  coil on the inside top has caused several spills with tall mugs. very disappointed with this puchase.
