Heater and fans not working.

No luck, fans are dead

Looks like I have received a DOA board delivery

Does there appear to be any visible damage to the fan mosfets?

Would you be able to test the mosfets with a multimeter?

And just in case, have you confirmed that the fans themselves are working by connecting them to an always on fan header?

@phaedrux
As I wrote earlier no visible damage and fans verified with 24V
Yes, advise how
There is only 2 fan headers and both are dead.

@tecno, please can you post a close-up photo of those two fan mosfets.

What revision number is the board? It's printed on the underside.

@dc42

Hope these photos are OK so you get the info you need.

How is it revision 1? Bart only has V0.5 in stock!

droftarts

@tecno how is what revision 1? You have a revision v0.5 board, as it shows in your photos. There’s only tiny differences between v0.5 and v1, mainly to aid manufacturing; see https://duet3d.dozuki.com/Wiki/Duet_3_Mini_5plus_Hardware_overview#Section_Revision_1_Num_0
I guess RepRapWorld are still selling slightly older stock, which is fine.

This does not appear to be a valid Duet3D Warranty Authorisation Code

@tecno oops, sorry, we’ve just changed how we do warranty authorisation.

Please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out and warranty authorisation code.

@droftarts

Already filled the form without WAC (omitted the code so I could fill the rest) and cc to Bart.

So I think you can fill the blanks inhouse.

Yes, no problem.
