This is my second purchase of ge microwave center product... The first one lasted 25 years...and was a real workhorse... Decided to upgrade to current ge microwave center model... So far the unit has been in use for 2 weeks and the bridge board had failed.  Seems to be common problem with new units of this model.  Would have liked to see ge backlight all the push button controls as impossible to see if lighting is not full on in kitchen.  Seems to be design flaw to me...
