    Help……

    My ZX99/5si is almost 3 years old and has not missed a beat until last night! Without warning total power loss.

    I am an ex service engineer so was not afraid to take a look.

    What I found was – Resistor R25 had blown on the power card situated in the lower rear of the f/freezer(next to the compressor).

    I have ordered a new power card from Electrolux at a cost of £88 and wanted to know:

    Can I find out the value of R25 and replace it?

    Is this problem likely to be caused by anything outside of the power card?

    Unit details:

    928405933

    Type 8406957

    Can anyone help please?

    Hi Jamo,

    To be honest the tech info on component parts is not that detailed as to enable us to identify the value of each constituant componet that makes up a complete control P.C.B

    You are lucky today if having given the full and complete make, model,serial,and production numbers you are sent the correct complete part.

    But if you are serious about trying to identify the actual value of the resistor in question, and you can read the coloured rings on it then perhaps this link might help.

    but would you be able to put your hand on your heart and trust the repair if you only replaced a resistor. When we both know (due to you being an ex-engineer yourself ) that just like a blown fuse, a blown resistor is all too often, only a symptom rather than the cause of the fault itself.

    Why not consider calling in an expert from Repairs@

    Regards

    Thanks Del

    the resistor in question is not colour banded, its probably a suppression resistor of some kind – green in colour and has a marking of a {e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} which cannot be read due to the burn of the ceramic body.

    I was very surprised to see that there was no fused protection on the power card and thought maybe this resistor would be the first component to ‘fall over’ if a fault occured.

    Sounds like this particular model may not be that well know by the users of this site, hopefully someone could have the answer, but thanks for the advice.

    I will probably send the fauly card to electrolux for repair and fit the replacement.

    Thanks Again
