The DO30U/P is the Professional-handle version of Wolf’s 30-inch L Series double oven, unframed, with the same two-cavity, one-control layout as the rest of that lineup. At this age, uneven baking — front to back, or between the upper and lower racks in either cavity — is one of the more common calls, and it is frequently a convection fan issue rather than the heating element itself.
Because the two ovens share a control board but keep independent heating elements and sensors, isolating which cavity is actually to blame is the first real diagnostic step, before assuming the whole unit needs a board replacement. This generation’s control still writes its warnings as text messages rather than numeric codes, which helps narrow that down over the phone.
