I just had this oven installed.  I previously had a build in GE oven and it was great.  This oven seems to be working fine after the first week, however, the timer sound is too quiet.  I have the sound set to high, but you can barely hear it.  I was standing next to the oven with  other background noises and I missed the timer sound.  My food was over done as a result. Very disappointed in this feature.
