I would suspect that a cap that would be a short at mains voltage would very
quickly burn/melt or blow the mains fuse. Perhaps this site may give some ideas: http://www.irf.com/product-info/appliance/washer.html or if not, then.... http://www.angelfire.com/electronic/...sherandpaykel/ "Malcolm Fowler" wrote in message om... Hi, I have a Fisher & Paykel washing machine with Smart Drive (?) The main motor power module has "spat the dummy". The fuse blew and two diodes on the input bridge rectifier self destructed. No replacement modules are available. Can anyone give me a clue as to the most likely cause? Basically the mains is rectified and then passed on to what appears to be a 3 phase inverter motor controller. The motor may have shorted but it looks OK and I would have expected the diodes on the control side to have blown - they are OK. I am suspicious of the mains filter capacitor (10mfd 250v) but it tests OK as 10mfd when removed from the circuit - but could it still be an effective short at mains voltage? Any suggestions would be appreciated |
