I have a Lowe’s tech coming to measure the space and see what they can do so I can put this by him :)
By the way, this house is 20 years old and we just had the GE microwave replaced for the 4th time.
The local family owned appliance store we use has their own service people and because we have all our appliances from them we’ve gotten to know the service guy over the years. He said three to four years is now the average lifespan for these above oven microwaves. And he said it really didn’t make a difference on the brand. My daughter said that we may as well think of it as a $100 a year service fee to own the microwave. Be a lot funnier if it weren’t so true.
