2. With an Ohmmeter measure the resistance between
pins 12 and 13 in the plug (not on the control board).
If the meter reads around the value of the oven
temperature sensor shown in the below resistance
chart, 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
reading is 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 control will not program check for an open sensor
circuit. If the sensor circuit is good replace the control.
Blank display:
If the display on the oven control is blank and the range
connected to electrical power:
1. 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 (120VAC) the
control is defective. If the meter reads zero the
wiring in the range is defective.
No heat:
If the control appears to be operating normally, but the
bake element does not heat:
1. 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).
RTD SCALE
Temperature (°F) Resistance (ohms)
32 ± 1.9 1000 ± 4.0
75 ± 2.5 1091 ± 5.3
250 ± 4.4 1453 ± 8.9
350 ± 5.4 1654 ± 10.8
450 ± 6.9 1852 ± 13.5
550 ± 8.2 2047 ± 15.8
650 ± 9.6 2237 ± 18.5
900 ± 13.6 2697 ± 24.4
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
line to line voltage (240VAC) the element is defective.
If the meter reads zero the wiring to the element is
open.
If the control appears to be operating normally, but the
broil element does not heat:
1. Go to the back of the oven control and measure the
voltage drop between terminals BR 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 broil element
or the wiring to the broil element is defective. Go to
step 2.
2. Remove the back from the range to gain access to
the terminals of the broil element. Program the oven
control for broil and measure the voltage drop across
the terminals of the broil element. If the meter reads
line to line voltage (240VAC) the element is defective.
If the meter reads zero the wiring to the element is
open.
Oven door does not lock when the oven is pro-
gramed for clean:
1. Remove power from the range, go to the back of
the control and disconnect the 15 pin plug.
Measure the resistance between pins 5 and 6 of
the 15 pin plug (not on the EOC). If the meter
reads infinity the lock motor or the wiring to the
lock motor is defective. If the meter reads around
1500 ohms go to step 2.
2. Measure the resistance between pins 9 and 11 of
the 15 pin plug with the oven door closed. If the
meter reads infinity the door switch or the wiring
to the door light switch is defective. If the meter
reads zero go to step 3.
3. Measure the resistance between pins 9 and 10 of
the 15 pin plug. If the meter reads infinity the lock
switch or the wiring to the lock switch is defective.
If the meter reads zero the control is defective.
