In reference to my previous intervention regarding code F20 on my Fisher and Paykel fridge, I got a problem with the flatter right after this code F20 was taken care of. I think that the wire inside the door hinge is there as a warning of a bigger problem to arise. Therefore, I apologize for suggesting that this was a manufacturer's deliberate intervention and realize that if that buzzer had not been bothering me enough to look for the problem, I would have had a bigger repair bill to pay at the end.
