How to turn off Air Assist Fan print block

My Glowforge has some sort of issue. I have no magnets in it, I replaced the carriage plate with one directly from GF, and I can print some days, and others not. If I turn off the GF, turn it on, run a print, it’ll work. But if I print a larger item, it’ll stop midway with this error. Or, if I try two prints at a time.

Also, yes, my carriage plate fan starts running at full speed immediately. But its a brand new one I bought from GF. So, not sure about that.

Support has not been helpful. I’m not in position to pay thousands to ship it off for repair or get a replacement. While I’ve had GF for years, it’s really got light use on it. Nowhere near the initial cost. So I’m disappointed. Anyone know how to bypass this error? GF works fine otherwise.

(Another note, during longer prints, the error will pop up, then, disappear and automatically continue the print. That’s fine, but sometimes it’ll take 30 minutes before doing that.)

Since you had a fire, I wonder if the issue is not directly at the air assist (which would have been fixed when you replaced it), but further down the line. There are cables/wires that run through the bar that moves, and along the inside of the back of the machine.
Check to see if there’s any damage, ash, or debris on those? Try (carefully) popping out the connectors, blowing them off, and then popping back in?
