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

configured.

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 configuration alarm: the oven

user interface board received from the touch

panel a key code that does not match the

key map.


F13

Data written to non-volatile memory has

failed verification


F15

Keyboard error


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

configure 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.


F18

Oven relay board failure (wiggler)

Replace the oven relay board.

F19

The oven user interface board is unable to

configure the oven relay board

1.


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.


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.


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

interface and the touch panel cannot be

initiated.

1.


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.

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 first). 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 find the locked or unlocked position (ex: motor turns continuously until F90 fault code is

generated) the Lock Switch needs to be verified. 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 Mo-

tor 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.


2.

If fault persists, replace motor door lock.

3.

If fault persists, replace the oven relay board.
