Replace the back
power board
Replace the multi
point core probe
Replace the multi
point core probe
Measure the impedance
with the multimeter set to ohm
between the white
cable of the core probe
and all the other colorful cables
Test the ground connection of the
core probe, by measuring
electrical continuity between the tip
of the probe and the frame of the
oven with the multimeter set to ohm
Te st the ground connection of each wire
of the core probe, measuring the electrical
continuity between the wires and the frame of
the oven with the multimeter set to ohm
Do you
have
110 ohm at 25°C (77 °F)
between white and
each colored
cables?
Do you
have
110 ohm at 25 °C (77 °F)
between white and
blue wires?
Do you have electrical
continuity between the tip of
the core probe and the
frame of the oven
Cut properly the external armored
coating of the probe inside the
ground connection plate or check if
the ground cable is properly
screwed to the metal frame
NO
NO
NO
NO
NO
NO
NO
Do you
have the electrical
continuity between at least
one point and the frame
of the oven??
Check if the core probe socket
is well fitted in P14. Remove
and connect the socket
and test the oven
Remove each cable of the green socket and
connect again each PIN paying attention
to the color of the cable on the socket and
tighting properly each screw
Check if there
is anything
connected to the
P15. In case
disconnect
any connector and
test the oven
