aF01 – Motor tHerMal ProteCtioN (PerMaNeNt error)
AF01 motor thermal
protection alarm
Turn off the power supply, disconnect
the P2 socket and test the electrical
continuity between pin 4 and 5 which
corresponds to F and TM respectively
as labeled on the
Powerboard
with
the
multimeter set to ohm
YES
NO
Do you have
electrical
continuity on the
P2 socket?
Replace the back
power board
Unplug each motor
from the circuit and
check conductivity
between the white
cables of the motor
with the multimeter
set to ohm
NO
YES
Do you have the
electrical
conductivity?
Replace the motor
that has the thermal
protection circuit
open
Measure the electrical
conductivity of the cable
harness from the P2 socket to
the motor plug. Measure the
conductivity PIN to PIN with
the multimeter set to ohm
NO
YES
Do you have
electrical
conductivity?
Replace the cable
harness
YES
Restore the cable
harness and test the
oven
NO
NO
YES
Did you measure
6,3 µF for each
capacitor?
Replace the faulty
capacitor
Replace the power
board
End
Test the capacitors
NO
YES
Did you
measure6,3 µF for
each capacitor
with 5% tolerance
?
Replace the faulty
capacitor
YES
NO
Does the alarm
persist?
End
persist?
Does the alarm
YES
