Arrived at location on 3/6/22 - Received call from Billy that his griddle was down and he requested emergency service for unit. Arrived to location and found unit. The unit was extremely difficult to work on because staff were using it. I started inspection and believe the thermocouple was the culprit. Unfortunately, unit is a magic kitchen, I cannot find parts or part diagrams of unit. I believe it is an avantco product but could not find parts. Staff repeatedly got raw egg and product dropped on me while trying to work. Unit too difficult to further diagnose due to lack of space or room to tear unit further. From searching online I found a similar part that may work but cannot guarantee due to manufacturer being closed and no diagram availability. Will put an order in for part. Unit in service. Returned to location on 3/11/22 - Removed top panel and lowered bottom. Removed pilot assy and removed t couple from it. Installed new one and put assy back in. Installed other en
