Thanks, When I checked the switch I checked it at the control panel including wiring to switch, so guess its control panel. I figured it had to be, I just didn't want to spend a couple hundred for it and have it not fix the problem.

It was not a numerical error code. It was in plain english!!! DOOR

I replaced the control unit on the stove a year ago - clock set button & oven start didn't work. Everything appeared to work fine after I replace it, but I didn't check to see if Oven Clean feature worked. We seldom use the oven & normally don't get it dirty. Now it is dirty and when we turn on self-cleaning we get a "door" error message. I unplugged & pulled back off and get continuity on oven lock switch at the control unit when I lock for cleaning and open when self-cleaning lock is not engaged. Is there anything other than the control unit that can cause this failure. Oven works fine otherwise - both elements! Just can't clean it!
