Need to locate the thermal temp sensor, ground wires. I think that is what controls the fan.
Sorry. I don't currently know where they are. But this has been reported as a similar issue before.
I have a P700 with the same problem. Good Fuse no fan.. I have a repair manual ordered . I would really like to know all the components in the circuit so I could go ahead and troubleshoot it.
My 1000 done the same thing overheated fan stopped working and then it wouldn't start. Let it sit for a few minutes then started up but fan still did not work for quite a while
