JL (Zanussi) T Dryer dead?

[iadom]

JLTDC09…Pnc 91609633703.

Mains up to main pcb but display is totally dead. I did check on the mains socket and found the polarity reversed but it has apparently been used on this socket for some time. Just in case I did try it in another good mains socket but no joy. I am assuming the pcb has died, unless you know better. 😉

It sure sounds like it Jim. I bet it’s just a cap or resistor that’s given out on that board.

i think there’s reference to this problem in the pcb repair tips?

Would be grateful if you could point it out, just scrolled through the whole thread twice and couldn’t see any mention of Zan/Lux T/D pcb’ ?

From Memory you need to change the SMPS chip (LNK304 I think) plus the fusible resistor and the bead inductor, if I remember correctly it uses basically the same power supply circuit as the Whirpool washing machine and tumble dryes but with a different value inductor and resistor.

Could the fact that it was plugged into a socket that had reverse polarity have been likely to have caused the failure, if there had been a power surge for instance?

The reverse polarity shouldn’t have made much difference although it may be possible.
My personal experience is that this range of smps chip will run for 6 to 7 years and then fail for no obvious reason after which it blows the bead style inductor and then the fusible resistor blows to stop further damage.

Thanks for that info, may be a little late in this instance as she said she wants a new dryer but worth knowing about for the future.
