We replaced our previous Advantium oven because thE main computer board died and it wasn’t worth the expense to replace it in a 14 year-old unit. We purchased a new one and it was a simple slide-in/slide-out installation. The new oven is noticeably quieter than the previous unit, which was a bonus. The only down side to the whole process was the extreme delay in delivery due to supply chain issues. The new oven is functioning perfectly and we are happy to have our kitchen fully back to operation after several months w/o a microwave.
