Professional trim finishes the CSO3050PM/S/P, the later-generation M Series convection steam oven at 30 inches, running the same reservoir, steam generator, valve and drain path as the rest of this control family. Pro handles are the only visible difference from the handleless and transitional trims in the same generation.
Water pooling under the door on an oven this recent is less likely to be simple age and more often points to a seal that was never seated correctly or has since shifted — worth checking soon regardless of how minor the pooling looks, since steam ovens are less forgiving of a compromised seal than a dry oven is.
Key Features
- 30-inch convection steam oven: dry convection, steam, and the two combined
