Self cleaning cycle is automatic, take shelves out, lock oven and turn on self cleaning. Cycle is over in about 4 hours, oven door locks. Had smaller kitchen aid double oven for 25 years. never had problems with self cleaning on top oven. Bottom oven, the self cleaning went out. (Probably used self cleaning maybe 10 or 11 times). I had AHS and they replaced double oven with a double oven with convection on top. Best deal I could ever make. .It would be important to make sure it is a dedicated electric line.
