Temperature Adjustment
1. Make sure both the oven mode selector and the oven temperature selector are in the OFF position.
Press and hold both the light icon and the clock icon at the same time for a few seconds until the
display sounds an acceptance chime. AUd should appear in the display.
2. Press the + key in the upper part of the display until UPO appears and the default setting of 0° (or the
last set temperature offset) is showing.
3. Using the + or - key in the bottom of the display, press until the desired temperature change (offset)
is reached. The display will change ± 5° with each key press to a maximum of +35° or a minimum of
–35°F. Once the new offset appears in the display, release the key and the control will accept the
change.
4. To return the display to normal, press and hold both the oven light icon and the clock icon at the same
time until an acceptance chime sounds. The display will return to show the time of day.
Note: Changing calibration affects all baking modes. The adjustments made will not change the broil
self-cleaning temperature.

ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS
Fault
Code
Description of Error Code Suggested Corrective Action
F01 F02
F04 F05
Touch panel failure Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the control assembly (UIB and touch panel).
F03 The oven user interface board is incorrectly
congured.
Replace the control assembly (UIB and touch panel). Make sure you install the latest revision available for this model.
F10 Oven temperature runaway: the cavity tem-
perature has been detected in excess of the
maximum safe operating temperature.
1. If oven is overheating, disconnect power. Check oven temperature probe (RTD) and replace if necessary.
2. If the oven temperature probe is good and if oven continues to overheat when power is reapplied, replace the oven relay board.
F11 Stuck key: a key has been detected has pressed
continuously for 30 seconds or more.
1. If a key was pressed inadvertently for a long time this error code will be displayed. Make sure there is nothing (water, utensils) in contact with the keyboard. The
fault code should go away once the key is released and the Stop key is pressed. If the F011 error comes back when a key is pressed it means the error condition is
still there. If the F011 error does not come back it means the error condition is gone and the oven can be used.
2. If the fault code cannot be cleared, test the wiring harness between oven user interface board (connector I2C1 or I2C2) and touch panel (connector I2C1 or I2C2).
3. If the fault code cannot be cleared and the wiring is good, the touch panel is most likely defective: replace the control assembly (UIB and touch panel).
F12 Keyboard conguration alarm: the oven user
interface board received from the touch panel a
key code that does not match the key map.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the control assembly (UIB and touch panel).
F13 Data written to non-volatile memory has failed
verication
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the control assembly (UIB and touch panel).
F15 Keyboard error Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the control assembly (UIB and touch panel).
F16 The oven user interface board cannot read the
potentiometers.
1. Verify that potentiometers are in OFF position correctly, disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify harness going to the POTS connector of the user interface board to both potentiometer components.
3. If fault persists, replace potentiometers.
4. If fault persists, replace the control assembly (UIB and touch panel)
F17 The oven user interface board is unable to
congure the touch panel.
1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify harness going to I2C1 or I2C2 connector of the touch panel.
3. If fault persists, replace the control assembly (UIB and touch panel)
F18 Oven relay board failure (wiggler) Replace the oven relay board.
F19 The oven user interface board is unable to
congure the oven relay board
1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify connection between the oven user interface board (MACS1 or MACS2 connector) and the oven relay board (connector J3 or J4).
3. If fault persists, replace the control assembly (UIB and touch panel)
4. If fault persists, replace the relay board.
F22 Communication failure between the oven user
interface board and the oven relay board
1. Disconnect power, wait 30 seconds and reapply power. Check if error condition is still there.
2. Test wiring harness between oven user interface board (connector MACS1 or MACS2) and oven relay board (connector J3 or J4).
3. If wiring harness is good replace oven relay board.
4. If the problem persists replace the control assembly (UIB and touch panel).
F23 Communication failure between the oven user
interface board and the glass touch panel
1. Disconnect power, wait 30 seconds and reapply power. Check if error condition is still there.
2. Test wiring harness between oven user interface board (connector I2C1 or I2C2) and touch panel (connector I2C1 or I2C2).
3. If wiring harness is good replace touch panel.
4. If the problem persists replace the control assembly (UIB and touch panel).
F25
F27
The communication between the over user
interface and the oven relay board cannot be
initiated.
1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify connection between the oven user interface board (MACS1 or MACS2 connector) and the oven relay board (connector J3 or J4).
3. If fault persists, replace relay board.
4. If fault persists, replace the control assembly (UIB and touch panel).
F28
F29
The communication between the over user inter-
face and the touch panel cannot be initiated.
1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault returns, verify touch panel is connected (verify harness going to I2C1 or I2C2 connector) and is getting power from the oven user interface.
3. If fault persists, replace the control assembly (UIB and touch panel).
F30 Open oven temperature sensor (RTD) 1. Check probe circuit wiring for possible open or short condition.
2. Verify RTD resistance at room temperature (compare to probe resistance chart). If resistance does not match the chart, replace the RTD probe.
3. If the problem persists replace the oven relay board.
F31 Shorted oven temperature probe (RTD)
F33 Meat probe temperature sensor shorted or
too hot
1. The error is triggered if the meat probe sees a temperature in excess of 392°F. Make sure the meat probe was not used in such way that it could have seen such
temperature. If the tip of the probe is not inserted in the meat it will see the cavity temperature, which can be higher than 392°F (depending on the setpoint) and
trigger the alarm.
2. When the meat probe is connected to the socket inside the oven cavity, if the meat probe is not fully inserted into the socket it may short the contacts and cause
the error. Make sure the probe is inserted as much as it can.
3. Verify meat probe resistance at room temperature. Compare to meat probe resistance chart. If the meat probe does not match the chart, replace it.
4. If the above steps failed to correct the problem, replace the oven relay board.
F45 Cooling fan speed too low 1. Check if the cooling fan blades are blocked.
2. Conrm tachometer harness is connected on fan and on oven control.
3. Replace cooling fan.
4. Replace oven control.
F46 Cooling fan speed too high 1. Check for mechanical obstruction in the air path.
2. Replace cooling fan.
3. Replace oven control.
F50 A/D Out of Range: the oven relay board is unable
to read the status of the switches (door, MDL)
Replace the oven relay board.
F90 Motor Door Lock mechanism failure. The oven
control does not see the Motor Door Lock
running.
1. Disconnect power to the unit, wait 30 seconds, then reapply power. Try again to make the door lock or unlock (ex: initiate a Lockout or a Clean cycle).
2. Check if the Lock Motor is running or not. If it is not running, test the wiring between the Lock Motor and the oven relay board. If the wiring is good, check if there is
120VAC at the motor when it is expected to run to see if the failure originates from a bad motor (120VAC present but not turning) or a problem with the relay board
(J20 pin 10 on the oven relay board is the output to the Lock Motor). The Lock Motor can also be tested by applying 120VAC directly to the motor (unplug it from
the relay board rst). If the Lock Motor does not run when 120VAC is applied replace the Lock Motor Assembly. If it is the relay board that does not provide 120VAC
to the Lock Motor replace the oven relay board.
3. If the Lock Motor is running but the oven control cannot nd the locked or unlocked position (ex: motor turns continuously until F90 fault code is generated) the
Lock Switch needs to be veried. Check wiring between Lock Switch and oven relay board. Verify with ohmmeter if the switch makes contact properly (verify
continuity with ohmmeter when the switch is pressed). If the Lock Switch is defective replace the Motor Lock Assembly.
4. If all above steps failed to correct the situation, replace the oven relay board.
F95 Motor Door Lock mechanism failure. The Motor
Door Lock does not stop running or the Lock
Switch sends an invalid signal.
1. The problem can be caused by a faulty Lock Switch or by a defective oven relay board. If the Motor Door Lock is always running (as if the relay controlling it is
stuck closed) replace the oven relay board.
2. If the motor is not always running replace the Motor Lock Assembly.
F96 The oven door has been detected open during a
Self Clean cycle.
1. This error occurs if the door switch has lost its contact during a Self Clean cycle. Make sure the oven door closes well and fully presses on the door switch plunger
when the door is locked, and no one attempted to pull on the oven door during the Self Clean cycle.
2. Test continuity of wiring between the door switch and the oven relay board, make sure the door switch is well connected. With an ohmmeter, verify the switch is
closed when the plunger is pressed. If the door switch is found to be defective replace the door switch.
3. If the switch and wiring are good and the problem persists, replace the oven relay board.
F97 MDL invalid state. Relay board (OVC) sensed
the motor door lock in a state it should not be in
according to the user interface board.
1. Disconnect power to the unit, wait 30 seconds, then reapply power.
2. If fault persists, replace motor door lock.
3. If fault persists, replace the oven relay board.
