Zanussi PCB R93 resistor value

[dunston]

Does anyone know the resistance value of R93 on a EWM2100 board.?
The replacement board is part number 973914606027-00/6

Re: Zanussi PCB R93 resistor value

have a few of that board round here but have nicked the resistors. that resistor serves 2 jobs
1 it a surge resistor to limit the charging current of the main caps
2 its a safety resistor which can blow if things go wrong

I would use a 3watt 47 ohm fusible resistor which should fit the bill but if that resistor has blown I would also expect the power chip to be faulty also

Thanks Dave.
The resistor has broken up that’s why i couldn’t read the value.
Have you every changed the power chip? Do you mean the link switch?

Re: Zanussi PCB R93 resistor value

done lots of them

resistor can blow for various reasons but the power chip is most likely. resistor feeds the power through a diode to charge a capacitor to about 300 volts DC. if the diode or cap fail will also blow resistor as that is part of its job
