Self fix. Appliance Pros one of the few companies that stock part needed. The one authorized repair firm for South Florida that I was referred to by both Thermador's Customer Service 800 number and by two of Thermador's product distributors in the area doesn't even stock any Thermador parts. Not just considerably less costly, but also easier and much quicker for me to order from Appliance Pros and do myself. I requested only standard, low cost shipping when I placed order well after their deadline for guaranteed same day shipping. The part was delivered to my doorstep the next afternoon! Exactly what I ordered. No hassle. Quick!
