Page 18: Hidden Bake Element
Hidden Bake Element Before disassembling the range to access the hidden bake element, check the resistance of the element by disconnecting the plug and checking between the orange and yellow wires. The resistance reading of a good element is approximately 21.7Ω. If the hidden bake element does need to be changed, the procedure is the same as for the previous version of the dual cavity oven. -

Page 24: Key Panel Test
Key Panel Test Touch each pad. Pads should light in response, except CLEAR/OFF and COOKTOP Pads. Each pad must be individually tested. Number pads, +/-, etc., respond only after a function is selected. LIN Test Press the OVEN LIGHT pad. Corresponding relay(s) should click and oven lamps should respond. If successful, LIN bus is not the cause of nonworking elements. -
Page 25: Oven Sensors
Oven Sensors The current software version of the main logic board will cause the cooktop to become inoperative if either of the sensors open. If either sensor opens and the fault code sets to epprom memory (this takes about 3 min.), the cooktop will become inoperative until the sensor is replaced. -
