The Dimango 3250 wireless door chime stopped working. Resistor R32 with the gray ash looking coating appears to be the worst fried part. Is it possible that only this 1 resistor went bad and everything else is okay?
Seems like this resistor is part of the voltage reducing area of the circuit. Could I put x VDC downstream of where the 110AC is reduced and see if the rest works? If so what would the voltage be? In the old days, I got things working by replacing bad transformers and rectifiers, but this seems to use resistors and diodes to convert the high voltage down.
I already spent more time than it would cost to buy a new one of these, but I'm a repair rather than replace kind of guy, so if there's an easy fix I'll try it.
Thanks for the help,
Mike
