Thermador built in oven - relay board

I have a Thermador built in oven w/warming try and microwave, model SMW272YS . The bake function for the oven stopped working, although the others still work. I checked the bake element and it seems okay. I happen to have a spare relay board and tried to change it. I removed all the panels for the display and touch pad covering the area the relay board is mounted. However, there isn’t enough space to physically remove the board, and I cannot figure out what else can be removed. The wires hooked up to it are too short so I cannot even pull the board out enough. Anyone have a detailed diagram or any tips? This is horrible timing with Thanksgiving being tomorrow!
