I had a fire in my home years ago. I found out that SOME appliances can be cleaned --- that black smoke gets INSIDE....do NOT try to start it again. Have the repairman look at it to determine. In my case, the ONE appliance I had and loved was my toaster oven. It was the best I've EVER had. When they got inside it.....the wires were melted. So it couldn't be repaired. Other things were repairable. Get it done ASAP....that black smoke is acidic and will destroy the innards within 6 months.
