This part is the replacement A/C fan motor or convection fan motor for your range. It is used to spin the fan blade, which circulates hot air through the oven, and ensures even heating. If you notice ...
Go onto youtube, such as https://www.youtube.com/watch?v=-ITkrwhDNMQ and watch similar videos for DYI. The process is very similar to other models.
Once the door is removed, place oven door on a towel or soft place so it does not scratch the door. Unscrew the screws and make sure you notice where each screw goes, so you know the process of where each screw goes when you re-assemble.
Once the inner cover is removed, remove the insulation, too so you don't damage it. Use Wet/Dry Shop Vac to clean the shattered glass. (WORD OF ADVICE: I did not remove the insulation and the suction of the Shop Vac removed part of the insulation, so now instead of a quick turn around repair turns into a few weeks repair, because the insulation is on back order 10-14 days from the supplier. DON"T MAKE THE SAME MISTAKE!)
Once the glass has been removed, the new inner glass is replaced, begin by re-assemble the oven door with the correct screws and attached the oven door to the range.
I searched online and found someone that seemed to have the exact problem. That person had replaced the lower burner and the same PCB board I replaced. I was able to test the lower burner without removing it and it tested OK. The PCB board in the article I had checked was burned and obviously bad but mine was not. I took a chance and ordered just the PCB board. I replaced this board and the oven now works perfectly. I seems this board was not turning on the bottom burner but the system thought it was working fine.
Removed the back of the Range. Removed one wire at a time from the old PCB and placed it in position on the New PCB. Then secured the New PCB in the holder.
