F6 Code: - Electrolux 30" Service Manual

Harness
Reconnect the harness, if the F5 is still displayed, go to
the righthand 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 1 and 2.
Pins 1 & 2
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 4 or above 12 volts DC replace the
mother board. If the F5 code still does not disappear,
recheck the harness and replace each user interface
boards one at a time.

F6 code:

The ESEC 5 system has a lockout feature built-in to the
control that works in conjunction with certain electronic
oven control to locks out the top elements when the
oven is in clean or when the lock feature is set on the
oven control. This feature is not used on ranges covered
in this manual. To bypass this feature a jumper wire is
connect, in the harness, between pins 1 and 2 of P11 on
the mother board.
When an F6 failure code occurs this means that either
the jumper wire is open or the mother board is defective.
To troubleshoot this, disconnect the harness from P11
and using an Ohmmeter measure the resistance between
pins 1 and 2 in the harness. If the meter reads open the
harness is defective. If the meter reads zero the mother
board is defective.
F7 code:
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.
P3
NOTE: When testing from an outside pin to the center
pin the potentiometer must be turned on.
