O.k. here goes.
I have a thermador convection oven/microwave/warming drawer oven
mod.# semw302. 9 months old. In the self cleaning mode after about 1 hour i get an erro code F-34. Factory rep/service man comes over, pulls unit & installs more insulation & a side vent gizmo. He says it`s a manufactue update fix. I try self clean last night & it`s still comes up F-34 erro code.
What the h--l is F-34?????????. And don`t tell me to check super heat
