Bake Element
The 240V 2400W bake element is concealed in the base of the oven.
Access to the rear of the unit is necessary when replacing the
element.
Refer to the Element Strip Diagram section to test the bake element at
the control module. A Bake Element Relay Test is also available in
Service mode. See the Service Mode section for additional
information.
If the wires are disconnected from the element terminals, an
ohmmeter can be used to check for resistance of ~24 ohms.
