The GE website details instructions for finding the model number on its electric ranges as of 2015. There are five different places to find the model number, most involving looking inside frames or moving removable parts.
The model number of a GE range may be printed inside the oven door on the front frame or behind the bottom drawer on the front-left leg. On an electric range, the model number is either under the front-left surface unit or under the center cook-top, if it is removable. The last place to potentially find the model number is inside the bottom drawer.
