Temperature Adjustment
Refer to the Use & Care Manual for directions on how to adjust the oven temperatures.
Modular Control Systems
This appliance is equipped with a modular system of controls. The modular system consists
of various boards which communicate with one another to drive cooking functions. Oven
functions, if available, operate through an oven user interface (UI or UIB) and an oven relay
board. Cooktop functions, if available, operate through a cooktop UI/UIB and a cooktop
relay board. There may be additional boards which work within the system to drive specic
functions (refer to the schematics and diagrams and this sheet). Low voltage operating and
communications power for the modular boards is provided through the wiring schemes.
The boards that generate low voltage operating and communications power depend upon
the individual control system (refer to the schematics and diagrams on this sheet). These
voltages are only the operational voltages. Do not use these voltages as conrmation of
communication between the boards. Communication occurs through software programming
on each board. This communication is not detectable by volt ohmmeters. The programming
is self-monitored and the UI displays will show error codes based on detected failures. The
individual boards are not eld repairable. See the schematics and diagrams included on this
sheet for more unit-specic details.

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 congured.
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
temperature 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 sec-
onds 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 conguration 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 verication
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 un-
able to congure 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 un-
able to congure 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 oven
user interface 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 short-
ed 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. Conrm tachometer harness is connected on fan and on oven control.
3. Replace cooling fan.
4. Replace oven control.
