Reconnect the harness, if the F5 is still displayed, go to
the right hand user interface board as viewed from the
rear of the range.  Notice that the harness to this board
has four wires and five pins.  Disconnect the harness
plug from the board.  With a voltmeter set to DC volts,
using  a  scale  that  will  measure  up  to  sixteen  volts,
measure the voltage drop between pins one and two.

If the reading is between 4 VDC and 12 VDC the mother
board is good.  One at a time substitute a good user
interface board for the ones in the range.  When the F5
code disappears that user interface board is defective.  If
the reading is below four or above twelve volts DC replace
the mother board. If the F5 code does not disappear
recheck the harness and replace the user interface
boards one at a time.

Indicates a failed potentiometer, a user interface board
or the harness between the mother board and the user
interface boards. To determine which has failed, check
the resistance of the potentiometers. The resistance
between the two outside pins should be within 10% of
the potentiometer value (black 10,000 Ohms, gray 20,000
Ohms). From the center pin to an outside pin the
resistance should vary between 500 and 9500 Ohms on
the black and 1000 and 19,000 Ohms on the gray, as
the shaft is turned.

NOTE:

When testing from an outside pin to the center
pin the potentiometer must be turned on.

If the potentiometers test good, remove and Ohm out
the harness. If the harness checks good, reinstall the
harness and replace one of the user interface boards
with a new or known good board.  Turn one of the top
elements on.  If the element operates normal, replace
the user interface board.  If the F7 reappears, turn the
top element off, reinstall the board that was replaced
and replace the other user interface board.  Turn one of
the top elements on.  If the element operates normal
replace that user interface board. If the F7 still appears,
recheck the harness.

Blank display:

If the display remains blank when an element is turned
on, listen to see if you hear a beep when the element is
turned on. If the range beeps, one of the user interface

Potentiometer test

Indicates a commnunication failure between the mother
board and the electronic oven control. This failure could
be caused by a defective wire harness between the EOC
and mother board, a faulty mother board, or faulty EOC.

Test the wire harness from the EOC to the mother board
with an ohm meter. If the harness checks good replace
the mother board. If the fault code is still present then
replace the EOC
