I am currently looking at repairing the motor control board for a fisher and paykel mw059 washing machine. There is quite a bit about this board on the net and also some discussion on this forum. I haven't been able to find any solution as yet.
It has a blown thermal fuse and two transistors gone. One of them , an IGBT in the circuit to pump A had been getting hot for some time as there is considerably brown on the board. The other one has blown apart and I cant read the type. It also is in the pump a circuit and directly connected to the emitter of the IGBT
I have read that this is a common problem.
There is 340 volt on the power side of the fuse but until I find the source of the short I cant check anything else. I am setting up a couple of 240v light globes to use as a temporary fuse.
Any information would be appreciated. The washer went for 12 years so I cant really complain however I would like to get it going again if I can. (not worth a new board)
Regards
Brian
