DIAGNOSIS & TROUBLESHOOTING
DIAGNOSTICS
Before servicing, perform the following checks:
• The most common cause for control failure is
corrosion on connectors. Therefore, discon-
necting and reconnecting wires will be nec-
essary throughout test procedures.
• All tests/checks should be made with a VOM
or DVM having a sensitivity of 20,000 ohms-
per-volt DC, or greater.
• Check all connections before replacing com-
ponents, looking for broken or loose wires,
failed terminals, or wires not pressed into
connectors far enough.
• Voltage checks must be made with all con-
nectors attached to the boards.
• Resistance checks must be made with power
cord unplugged from outlet, and with wiring
harness or connectors disconnected.
FAHRENHEIT (° F) TO CELSIUS (° C)
CONVERSION
The default is Fahrenheit (° F).
1. Press the BROIL pad for 5 seconds. The
temperature will be displayed in degrees
Celsius indicated by the “C” in the tempera-
ture display.
2. To return the display to degrees Fahrenheit
press the BROIL pad again for 5 seconds.
“F” will show in the temperature display.
PROGRAMMING THE CAVITY SIZE
When replacing the electronic control, be sure
to program the cavity size:
1. Within 60 seconds of power up, press the
following touchpads:
LOWER OFF, UPPER OVEN, BAKE, TEMP
DOWN, TIMER OFF, MINUTE DOWN,
START, CLOCK, LIGHT.
2. The size is shown in the display “-ID 24.”
3. Press the CLOCK touchpad until the cor-
rect size is displayed.
4. Press the CANCEL touchpad.
5. Press and hold the LOWER OFF touchpad
for 5 seconds to verify the programming.
ELECTROSTATIC DISCHARGE
(ESD) SENSITIVE ELECTRONICS
ESD problems are present everywhere. ESD
may damage or weaken the electronic control
assembly. The new control assembly may ap-
pear to work well after repair is finished, but
failure may occur at a later date due to ESD
stress.
• Use an anti-static wrist strap. Connect wrist
strap to green ground connection point or
unpainted metal in the appliance
-OR-
Touch your finger repeatedly to a green
ground connection point or unpainted metal
in the appliance.
• Before removing the part from it’s package,
touch the anti-static bag to a green ground
connection point or unpainted metal in the
appliance.
• Avoid touching electronic parts or terminal
contacts; handle electronic control assem-
bly by edges only.
• When repackaging failed electronic control
assembly in anti-static bag, observe above
instructions.
