Has anyone had any luck replacing the individual components on the 95du motherboard? I let the smoke out of it the other day and after realizing a new one is $600 i thought it would be worth a try to repair it. Does anyone have any tips/tricks to perform this delicate surgery? :cry:
 
I suspect that the problem might be finding out what went wrong to blow components. The owners of Scan marine do post here, so they may give you an answer, but I believe that they just replace the boards. My experience with many modern electronics, is that once one component goes, that some of the others were damaged, and have shortened life spans.
 
I agree with Bob; especially if the circuit board is multilayered. I have not looked at this pcb to say, thus I do not know if this unit is.

You could get lucky and the CPU and ROM was not damaged, and it may have been just a cap. If it were I would probably wholesale all the caps with high temp replacements (105degree C), if they were not already.. This would certainly be an easter egg approach looking for that needle in the haystack, hoping that the pcb was not damaged, unless you have the tools and ability to tackle a rebuild.

In other words you may have to chew on the approach and hope for the best. Good luck and have patience, hoping there is someone with some help beyond my mess here.

I really hate it when the magic smoke escapes!

That happened to my Wallas also. I was passing through Seattle and stopped at Scan Marine and let them take a look. They told me it should not have fried like it did (there is a fuse) - it was only a few years old. They replaced the board at no cost which was a big relief.

When mine started smoking I opened the cabinet door and reached under and pulled the power wires on the board. Don't know if I saved anything but I could easily see that what looked like a power transistor had fried. I suspected that some part had failed shorted, causing a large current draw that fried the transistor. All just speculation.

It would take some analysis of the board, but it might not be that hard to find the bad components. If you have nothing to loose go for it.

Good Luck

There are only two kinds of Wallas owners - those whose Wallas has gone out and those whose Wallas is going to go out...after our Wallas went out for the third time, we decide three strikes and it is OUT of here! Loving our Webasto for heat and our Gasone butane stove for cooking.
 
Call Scan Marine and talk with Mike. He is the one who works on them and he is always willing to talk and problem solve. 206 2853675

There's actually 3 kinds of Wallas owners. THe two you described and those who always ran diesel, always start and shut down on full heat and who never had a problem in 8+ years (like me).
 
You'd have to make that four. I had a Wallas, used Clean Heat, and eventually replaced it with an Origo alcohol stove. A stove with a motherboard? Sort of the opposite of KISS, and not something you'll repair on a frosty morning with raw bacon already in the skillet.
 
This is our first year with the orgio stove and susan loves it. easy to light, fast to heat and easy to turn off. can see a down side to it.
another brat sent it to me for free and man what a gift it has been. works like a charm.

I'm also a member of that third group...

Another member of the third group. Eight years with Wallas and never a failure. Always use Kleen Heat., start and stop on high.
 
Another member of the third group, just past 8 years, have used all three of the various fuels (diesel, kerosene & Kleen Heat).
 
6+ years with Kleen Heat, and not so much as a hiccup. Start and stop on high. Make sure there's sufficient voltage to start. Don't shut the battery off until the fan has quit running on cool down.

Which model?
Is it a stove or the heat pal?

Kinda like Toyota owners Huh? Those who have terrible problems, those who are gonna have :cry Too much of a narrow statement counselor! As others have said, there is a third option which may involve luck (or following instructions which us guys hate to do!!). But, I gotta admit, if you do, it sometimes works. I'm also of the third variety!!

So sorry you and Patty and Baxter missed Powell! Sounds like the lemonade was good though.

Only thing the Toyota owners worry about is not stopping. It's the Datsuns that sometimes won't get going.
 
Have had several Toyota Trucks, never a problem, was just funnin' Sir Pat!

Now the new (to us) Ford Excursion (from Dr. Bob) is another issue. That thing weighed in at 7120# unloaded with 3/4 fuel on board. Will weigh Thataway tomorrow, on the trailer along with tongue weight, etc. Then the Trailer (Float-On) empty. I think I need to move the boat back about 12" to avoid heavy front end weight. Don't want to use an equalizing hitch..
