Trouble shooting: Rocker switch "blew-up", fire flew when wife opened oven door.
Assumed rocker switch was burned due to melted plastic and a terminal blew off. Down draft fan would not run.
Put stove breaker in off position. Search on internet located "Part Select". Entered Model number and discription. Picture of switch and simple diagram appeared on screen with part #.
I ordered part, it was here 2 days later.
Eating home cooked meals now. Bragging about repairing my stove, Repair savings of about $150.00.
