POSSIBLE CAUSES
HOW TO VERIFY
1 One
or
both
defrosting heaters
are interrupted
Freeze the battery, then unplug the
appliance, disconnect the connectors
of the heaters and check with the
tester the correct resistance value to
the connector clamps.
If the value of the resistances does
not correspond to the technical
data, replace the heaters and
overload cut-outs assembly.
2 One
or
both
thermal overload
cut-out switches
are open
Freeze the battery, then unplug the
appliance, disconnect the connectors
of the heaters and check with the
tester the correct resistance value to
the connector clamps.
If the value of the resistances does
not correspond to the technical
data, replace the heaters and
overload cut-outs assembly.
3 Timer
blocked
or
faulty
Unplug the appliance, place the
thermostat knob on ON, then access
timer box and measure with the tester
the electrical continuity:
a) between the clamp 1 of timer and
the line clamp of the feeding plug;
b) between the clamp 3 of timer and
the clamp of the feeding plug
neutral wire.
If the resistance values of the two
measures [ a) and b) ] are 0
Ω
then
replace the timer.
Burn out lamp:
After replacing the burn out lamp, verify the correct operating of the light button
P
with its manual actioning then
try again, actioning the light button from the closure of the refrigerating door and verify the switching off of the
lamp moving slightly the magnetic seal of the door.
Warning
:
the
Q
lamp holder seal is a component that concerns the appliance safety; therefore it is
obligatory to insert it again into the lamp holder after an eventual replacement of the
lamp!
