Dynasty 350 Parts

[bulletfab]

Hello All, this is my first post. I have a Dynasty '350' LJ01185L with a bad PC5 board (Aux. power with program)
Miller part # 233 139.I have two questions if someone can help. First question is my board has a different number
on it. (221 722) So just want to verify the Miller # from the parts catalog is compatible. Second question, I have read here
one may buy parts from a company called Miller 4 less. Is this company affiliated the Miller?

Regards, Mike

Welcome! I don't know if Miller4less is associated with Miller but I suspect they are. At any rate, they are the go-to place for genuine Miller parts. Cruizer is our resident expert tech-if he sees your post he can probably answer the part number question. Or you can just call Miller tech support. Super people always helpful. 920 734 9821

Thanks Aeronca41, Tony @ Miller was very helpful. Miller4Less is an independent company among others that distribute miller parts. This is the first time
I have posted anything or even joined a forum. Showing my age now. How can I get in contact with Cruizer you mentioned ? I would have some technical questions for him if he is willing.

Regards, Mike

Cruizer is a professional welder tech, factory certified, in Canada. He watches most threads here when he's able and really knows his stuff. Just start a new thread with your questions and he will probably join in the discussion. There are a number of other really smart guys here also, so ask away. Great group here, that has helped me out several times, in one case saving me from blowing an expensive board in my Trailblazer. And I now have an avatar thanks to H80N!

Miller support is why I have Miller welders. Other people make some good products, but I don't think any other big guys provide help like Miller. There are no doubt some who would take issue wth that; everyone's entitled to their opinion, but that's mine. Also lots of good support reports on HTP (usaweld.com). Good place to look for supplies, great people.

Once again thank you. I will do as you say and start a new thread. Yes and I agree about Miller and their products. Been welding with Miller products
for 32 years and now just have my first issue with one of my three Dynasty's.

bulletfab, you have just been answered by two of the Wizards-I'm not one of them. 😊

Just an updated part# however, what makes you think this board is gone. I mean, its not a part that generally ever goes. Or do you have it in somewhere and they are guessing? Won\t come up as a error code......

The machine made a popping sound when turned on. Was dead. Took it in for repair. Estimate was 3200 with no guarantee. I decided to check it out myself. Found that the primary board (228493B) had blown a wire wound resistor. I was fortunate to find a new board and replaced it. Before powering up
I notice board 233139 had a blown pulse width modulator and mosfet.

Since I have the equipment and time I think I will try to fix it myself. If not I will invest the 600-700 and gamble there is nothing else wrong.

Brother, you lucked out and found the right place. I've read on other forums looking for answers to this and that, I even signed up for a few, usually because they required me to for some sort of permission to do something. I came here and asked a question on how to wire a drum switch to a split phase motor to power an exhaust fan that I wanted to reverse when needed. Yup, not a dadgum thing to do with a welder. Not only did I get the help I need before I let the smoke out of that motor, but I've met some excellent human beings too. And with 32 years of experience, hopefully you'll be able to help someone in return. I have no doubt that you have the knowledge to do so. <br />

A very gracious welcome to you, sir.

Cruizer likely has some insight into the probable failure mode...

his advice might save you a bucket of money & tears... in diagnosis and repair...

hard to beat the experience of somebody who has fixed the same model many times

Yes thank you Cruizer / H80N / Aeronca41 / and everyone else. I am amazed at the timely response you all have given. And I only posted my question
this morning. I can tell there are many generous people here. I hope and will try to return the favor if I can. I understand Cruizer you are a Miller tech in Canada? I don't know if this is out of line but would it be possible to get some input power voltages to board 233139 ? If this is proprietary info from Miller I apologize. Don't want to overstep my bounds.

Also possibly the main function of 233139 as well. By it's description from Miller does this board store the programable settings for the Dynasty?
