I was called to a home in Scottsdale Arizona to repair a Thermador wall oven that was not keeping temperature. Upon arrival, I found that the oven was not heating up to the correct temperature. I checked the oven's wiring and found that there was a loose connection. I tightened the connection and tested the oven again, and it was now heating up to the correct temperature. The customer was very happy with the repair and thanked me for my help.
