Diagnostics and Service Information
Service Test Mode (Factory Test Mode in Mini-Manual)
The electronic control system components may be tested individually for troubleshooting purposes. To enter
service test mode, the unit must be restarted. Within 5 minutes of restart, press the Push to ENTER knob, COOK
TIME and DELAY START buttons simultaneously and hold for 3 seconds. The display board will show Prod when
the service test mode has been entered. The temperature reading of the sensor will show to the right and left of
the center display. The right display of the temperature will only appear on a double wall oven unit. Once in this
mode, turn the TEMPERATURE dial to clean and follow the table below for testing all features of the oven. The
service test mode will time-out after 5 minutes. Re-enter service test mode to continue.
Note:
If the display is out, you cannot enter service test mode. If 12 VDC is present between pins 5 and 7 at
location CN7 on the logic board, replace the logic board. If 12 VDC is not present, replace the power supply
board.
The cooling fan will operate in test steps 1, 3, 5, 7, and 9.

Control Voltage
WARNING
Components are electrically HOT on control when voltage is connected to range. To prevent electrical shock,
use extreme caution when diagnosing oven with outer covers removed and power on.
Heat sinks on the power supply board are electrically live. Take special precautions when troubleshooting
with the power on. If the power board has failed, the board capacitor can hold a voltage charge on the heat
sinks. Wait at least 5 minutes after disconnecting power before servicing the power supply board.
Note: Voltage must be present across terminals L1 to N for control to operate.
