This stoves handles were loose and not acting properly. Unfortunately for the customer they did not get things fixed properly before it was too late. The customer was home making dinner and the dials on the stove were turned to the setting she needed (or so she thought). While we was cooking dinner she noticed that was she was cooking was burning and not cooking evenly. So she turned the temp down hoping that would help. What she didn't realize was the metal piece inside was not turning properly. She was actually making the temperature higher. Always make sure you are servicing your appliances. Thankful there was just some smoke damage this time but it could have been much worse.
