Need to replace the relay board what is the best way to get to it

Take the top of the range off by unscrewing the burner rings. They will often be stuck and care must be taken to not warp them by using pliers or some other gripping tool. Even then on occasion they will have to be drilled out if they are “welded” onto the burner tube from spillage and other contaminants. The access to the relay board is then apparent under the small service panel. Reseal this panel with aluminum tape when reassembling.
