My old but prized wall oven needs a new burner. With help I've pulled it totally out of wall looking for the Model No. with no luck locating it. My original paper work refers to it as a Model 1027B06 but all searches that I've tried don't recognize this no. Maybe it's just too old? My parts booklet says the burner is a part no. 293510 and was used on all models. Please help locating a new burner. JB
