I removed two retainer screws which released the outside panel. Next I removed 2 screws which hold the middle glass pane from one of its retainer brackets. The was another panel with 4 screws to remove before reaching the final glass inner assembly. Once that panel was reoved with the broken glass it was time to put the repacement glass assembly back together.
Had a technician from Home Advisor to check the problem out with my Whirlpool Double oven(1 1/2 old). Paid $60 to find the problem. According to the technician problem was control board and cost of labor and parts $465.00 Jumped on Part Select website, placed a question with my stove problem through the chat. Immediately they answered my question and told me the problem was the Terminal Block. Cost of part and shipping $25.00. Replaced it myself and everything works fine. Thank you, Thank you Part Select for your help and honesty.
