Dacor Wall Oven Code C73: Wrong Power Board Detection
The Dacor manual lists C73 as a COMM ERROR with two possible failures involving power boards.
Dacor PO130 wall oven — model notes, common issues and what to have ready before booking.
A Dacor Preference wall oven often sits at the center of a predictable kitchen routine, and that same routine makes the PO130 a good example of why regular use matters in repair. Heating elements, temperature sensors and door hardware all wear on a schedule set by how the oven is used. When a lock refuses to release or a code appears after a long roast, the household’s habits are useful information. Owners who know how often the oven runs at high heat can tell the technician whether the trouble began suddenly or followed weeks of heavy cooking. For your booking, enter PO130, describe how you use the oven, and copy any code shown on the panel.
