Hypertherm 45XP error code 3-10-1

[tinspark]

I just got the dreaded error code 3-10-1 on my Hypertherm Powermax 45xp (non-sync) today.
I couldnt hear any fan rattling or noise until I shut the compressor off and all shop noise.
The little fan was on its last leg. My shop is so noisy I cannot hear the fan or any fan noise
Pulled the fan out and ordered another one.

I did put it back together with the old fan and it does work but is hobbling along. and rattling like a honeymoon car dragging stringed cans down the road!
But I will hold off on cutting anything until the new fan comes.
We are still in the hot season here in central CA, USA and I do not want to fry a board or anything else because of a $65.00 fan....
I have worked this little plasma cutter hard over the last 6 years and have no complaints!

Same issue here with me on my PM65 and the new fan fixed it. Didn't order mine from Hypertherm, I found the exact same fan online for a fraction of the cost. Hope the new fan solves your problem. Good luck.
