We used to have an advantium oven as well as a wall oven built in until our advantium quit Dec 31. After a long wait, our GE profile PK7800KSS was installed. I am concerned about the longevity of the microwave in particular. The glass fogs up often when microwaving steamy vegetables. It takes a very long time for this to dissipate. We also have had trouble with the microwave control pad getting “confused” at times and not performing the tasks requested. Tonight the entire left side malfunctioned and would not respond. After turning off circuit breaker and turning back on, it came back on, however this does not inspire confidence, and we are worried that it will quit after no longer in warranty. This appliance is too expensive and too difficult to install to be performing this poorly. I am afraid to use the self clean function for fear of breaking the oven.
