I’m a french owner of a GF basic and I met temperature and cooling issue.
By the way, I can’t afford the 1000 USD shipping fee to send back my machine to the USA for repair.
For my part, this does not seem to be a lid black cable problem. I inspected it, it seems in perfect condition and the GF worked perfectly until the “cooling alert”.
My GF suddenly went into cooling alert and the exhaust fan started running. I let it run for hours without effect. Power off, reboot, leave the machine unplugged for several days, nothing works and the cooling alert persists with the orange button lit constantly as soon as the power is on.
I just tried again a month later. Everything seemed ok in the homing sequence until you hit the white button for the print. Immediately alert cooling, orange button, fan in continuous function and any command is blocked.
Yet the temperature is 21 ° C (70 ° F).
I printed the log file that reports an error:

I think there is a problem on the thermal sensor.
FYI, I cut vinyl records and this generated a lot of smoke may be toxic for cicuits and embedded electronic parts (GF told me that it was not laser compatible).
GF have said they can’t fix remotely and don’t want to send spare parts at the moment which is detrimental to foreign customers far from the USA. I’m not under 6 month garanty and I feel myself ready to open the beast and change spare parts (if GF give me a dismounting guide to do it in the right way)
If someone has already encountered this kind of problem and, above all, has managed to fix it, I am very interested.
For now my machine is under a blanket in my workshop, not great for the creation (nor a good advertisement for the after sales service of GF).
I like my GF and I want to go on cutting and burning amazing things so please help wanted
