Summary: The only reason we purchased this thing was to replace another GE microwave of the same dimensions that had been built into our custom kitchen. The old microwave began running on it's own and couldn't be turned off--thank God we were home when it began malfunctioning.
Summary: I replaced the previous model, JE1860, with the newer version after using previous for 10 years. I was able to make it fit the old trim kit with some shims and glue and it looks as good as the old! So far, it works very well, and I expect it will last another 10 years.
Summary: I bought this GE microwave appliance yesterday. I have not had luck with GE in recent years as I had 3 of my 5 GE Profile appliances fail or not perform as designed in my last home. My Wife said to give them another shot because she liked the looks of this microwave and it was in stock.
