I write from Italy as a result of a problem with my no-frost refrigerator (INDESIT BAN 34 NFP), I hope that in this forum, some of you can help me solve.
The problem is the inner light that no longer works, in fact a few days ago I was doing the cleaning in the fridge and I disassembled the column that contains the lamp holder when I'm done cleaning and I reconnected the plug that connects the lamp, I accidentally touched a contact, and I took the "shock". At that point I disconnected the plug from the mains and I reassembled everything, but strangely the two bulbs were burned and when I tried to replace them with new, did not work.
I then checked with the tester and instead of having 220V (voltage in Italy) have a value of 110V, for this reason do not light bulbs.
What could have happened? My refrigerator is operated from the motherboard and after a check there are no signs of burning, I thought it may have blown a TRIAC or a resistor or the relay (NAIS).
How can I tell what electronic component manages the output voltage that powers the light bulbs?
I hope someone can help me. thanks
