1. Disconnect the fifteen pin plug from the back of the
oven control that connects the sensor to the oven
control.
2. With an Ohmmeter, measure the resistance between
pins 14 and 15 in the plug (not on the control board).
If the meter reads around value of the oven
temperature sensor resistance chart shown below,
the oven control is defective. If the meter reads less
than 800 Ohms or more than 3000 Ohms, go to
step 3.
3. Disconnect the harness from the oven sensor and
measure the resistance of the oven sensor. If the
meter reads less than 800 Ohms or more than 3000
Ohms, the oven sensor is defective. If the reading
is correct with the chart, the harness is defective.
F9 code:
An F9 code indicates the control has detected a problem
with the motor door latch assembly. Check the contacts
of the lock switch, wiring to the lock motor assembly,
and the lock motor.
Control will not program:
If the EOC will not program check for an open sensor
circuit. If the sensor circuit is good replace the control.
Time bake does not operate:
If the normal bake feature operates but the time bake
feature does not operate, check to be sure it is being
programmed correctly. If it is being programmed
correctly, replace the control.
Convection bake and convection roast:
Neither the fan motor or the assist element operates:
1. Remove power from range. Go to the back of
the electronic oven control and disconnect the
15 pin plug. With the oven door closed, measure
the resistance between pins 10 and 12 of the 15 pin
plug (in the plug). If the meter reads open, check
the door switch and the wiring from the electronic
oven control to the door switch. If the meter reads
zero go to step 2.
2. Measure the resistance between pins 5 and 7. If
the meter reads around 10 Ohms the control is
defective. If the meter reads infinity either the wiring
to the fan motor and element is open or both the
fan motor and the element are defective.
If either convection bake or convection roast
operate normally but the other does not:
1. The EOC is defective.
Fan motor does not operate:
1. If the assist element is heating then the fan motor
itself or the wiring to the fan motor is defective. Also
check for a blocked fan blade.
Assist element does not operate:
1. If the convection fan is operating then the element
itself or the wiring to the element is defective.
Control does not operate in preheat:
1. If the oven operates in bake but not preheat, the
EOC is defective.
Blank display:
1. With the range connected to electrical power, go to
the back of the control and measure the voltage
drop between terminal L1 and neutral. If the meter
reads line to neutral voltage (120 VAC), the control
is defective. If the meter reads zero the wiring in
the range is defective.
Bake element does not heat:
1. With the range connected to electrical power, go to
the back of the oven control and measure the voltage
drop between terminals BA and neutral with the
control not programmed (clock operating only). If
the meter reads line to neutral (120VAC) the control
is defective. If the meter reads zero, the bake
element or the wiring to the bake element is
defective. Go to step 2.
2. Remove the back from the range to gain access to
the terminals of the bake element. Program the oven
control for bake and measure the voltage drop across
the terminals of the bake element. If the meter reads
