Bought this microwave to replace a 6 year old Whirlpool because light under the Whirlpool failed and couldn't be fixed.  Used my new microwave lightly - mainly boiling water and heating frozen veggies - for 11 days.  Went to boil some water in a Pyrex measuring cup and after a minute realized that while the microwave was running, it suddenly sounded much more quiet.  Got worried and opened the door at which point the display and all the lights went out.  Checked the breaker and the outlet; both are fine.

Needless to say, I will NOT be replacing this one with another GE!
