[hitchup]

We've been using the GE's M/C in Suites since 2006. For me, I either bake by pushing Convection Button or Microwave by hitting time and/or 30sec button. Never used both together.
Baking Banana Bread that takes longer than 1hr will sometimes shut the oven off early, but I just restart for the last 5mins.
Otherwise, we've had zero issues, only blown inside light. While those with upgraded Advantium have had the electron (?) go out in the earlier Suites.
