Dacor’s HWO230 doubles the Heritage Professional oven into a 50-5/8-inch tall double unit, both cavities 4.8 cu. ft. with Four-Part Pure Convection. Heritage manuals describe error codes as a letter followed by two numbers, and on a double oven the letter tells us which cavity is reporting.
A convection fan that starts to grind in only one cavity is common on ovens of this age, and it is replaced from the back of that cavity once the oven is out.
