type. As temperature increases the resistance value
decreases.
1. Remove the Right Side Panel.
NOTE: If right side panel is not accessible, this
component can be serviced by removing the Control
Panel.
2. Place a shielded thermocouple in the geometric
center of the oven cavity and determine the
temperature in the oven cavity.
3. Remove the probe lead wires from the solid state
temperature control.
4. Test the probe with an ohmmeter.
A. If the measured resistance values are inside
the given tolerance then the probe is
functioning properly.
B. If the measured resistance values are
outside the given tolerance then replace the
probe and retest.
1) Check oven for proper operation.
5. Reverse procedure to install.
