3- On having manipulated the inductor set, the aluminium support
might lose evenness, provoking again a wrong inductor
regulation.
5.1.5 NTC change
Warning!
On changing the NTC or ceran glass, it must be applied again above
the NTC the conductive silicone, because the fryingsensor function
depends strongly on the quality of the NTC measure.
The spare part number for this conductive silicone is 618647.
5.2 Fan checks
►
Check that the rotor is not blocked.
►
The operational voltage is 24 V DC.
►
It is possible to check the fan using a suitable direct current.
The fan can not be checked by measuring its resistance because it
contains a diode in series within its own electronics.
5.3 Coil checks
The inductor contains no functional parts except for the NTC
temperature sensor. Therefore, it is not usually the source of faults.
However, the following procedure can be followed:
►
Inductor checks must be performed without voltage.
►
Remove the mica film carefully so as not to damage it and
perform a visual inspection. Check that there are no burnt
areas.
►
Check continuity of the inductor with a tester (<10hm).
►
Replace the mica film carefully so as not to damage it.
Do not replace the inductor unless burnt areas are found or there is no
electrical continuity.
