Temperature Adjustment

1. While in a non-cooking mode, press and hold the Bake key for 3 seconds until UPO appears in the

display.

2. Use the number keys (0-9) to enter the desired adjustments (-35° to 35° F).

3. Press the Self Clean key to change the sign of the adjustment to a (-), if necessary. A positive adjust-

ment will not display a sign.

4. Once the desired adjustment (-35° to 35° F) has been entered, press START to accept the change or the STOP key to reject the change.

Note: Changing calibration affects all baking modes. The adjustments made will not change the self-cleaning temperature.

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.

Replace the oven user interface board. Make sure you install the latest revision available for this model.

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.

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 touch panel.

4. If changing the touch panel did not x the problem replace the oven user interface board.

1. Verify the unit has the proper oven user interface board and touch panel, based on the model number and parts catalog.

2. Replace the oven user interface board.

3. If the problem persists replace the touch panel.

Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up replace the oven user interface.

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. Verify the unit has the proper oven user interface board and touch panel, based on the model number and parts catalog.

4. If fault persists, replace the oven user interface.

5. If fault persists, replace the touch panel.

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. Verify the unit has the proper oven user interface board and oven relay board, based on the model number and parts catalog.

4. If fault persists, replace oven user interface board.

5. If fault persists, replace the 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 oven user interface.

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 oven user interface.

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. Verify the unit has the proper oven user interface board and oven relay board, based on the model number and parts catalog.

4. If fault persists, replace relay board.

5. If fault persists, replace the oven user interface board.

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. Verify the unit has the proper oven user interface board and touch panel, based on the model number and parts catalog.

4. If fault persists, replace the touch panel.

5. If fault persists, replace the oven user interface.

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.

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.

1. Check to ensure that the connections between the door switch, MDL and temp probes are properly connected. This includes all splices and junctions.

2. If the above step failed to correct the problem, replace the oven relay board.

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 gener-

ated) the Lock Switch needs to be veried. 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.

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.

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.
