Check actual upper oven temperature,
if > 650°F check sensor.
Check actual lower oven temperature,
if > 650°F check sensor.
Check actual upper oven temperature,
if > 950°F check sensor.
Check actual lower oven temperature,
if > 950°F check sensor.
Check membrane switch for connection or damage.
Check upper sensor, harness, and connections
Check upper sensor, harness, and connections

Test Mode
Press
BAKE
pad.
Enter 100°F using the number pads.
Immediately push and hold
BAKE
pad for appropriate oven
approximately 3 seconds.
This mode can also be entered by pressing the hidden pad
for 3 second located to the left of the lower oven light pad.
Used to view the actual oven temperature for both ovens at all
times, even when an oven function is active.
This mode will also display the current fault code for 5
seconds in the time digits.

Test Mode
This mode must be activated within the first 5 minutes of
power up.
Press BROIL and CANCEL pad for approximately 3 seconds.
If oven temperature is greater than 400°F, the Test Mode
cannot be activated or will abort if active.
Press and hold individual pads for 4 seconds to activate.
Display will have dashes in all segments to indicate the mode is
active.

Oven
temperature
adjustment
Push
BAKE
pad.
Enter 550°F using the number pads.
Immediately push and hold
BAKE
pad for appropriate oven
approximately 3 seconds.
To decrease or increase oven temperature. Push
AUTO SET
pad until negative or positive numbers appear. Oven can be
adjusted from -35° to +35° (-37.2° to + 1.6° C). To avoid over
adjusting oven, move temperature -5° (2.7° C) each time.
Push
OVEN CANCEL
button.
While increasing or decreasing oven temperature, this does not
affect self-cleaning temperature.
Holds offset through power outage.
