Xenon problems…

Good guess, but this amp is doing it after sitting on a shelf not hooked up for days.

It is possible the thermal sensor is messed up and telling the amp is too hot. I did some checking on it and it "seems" fine.

Couldn't hurt to replace it at this point ?

Could bypass it all together and just run a 12v source to the fan and install a manual control

Word word. Just throwing out some ideas.

These things don't have a blower motor resistor do they? Like cars have? I know my blower motor resistor went out in my truck and the only speeds it would work were full on or off, none of the middle speeds worked for the fan.

Easy fix...............go OLDSKOOL PG

I am getting really frustrated with Xenon amps. This one had a bad channel and after hours of work I found this trace burnt under this transistor in the attached photo. Finding something like this a royal pain in the ass. After fixing this I would guess this is not related to the fan staying on but I don't know for sure.

What you have there is the infamous "Xenon problem". Not sure about the fan staying on.

Wow, really? I thought the Xenon problem was a cold soldering issue... not blown traces! This is a bigger problem than I thought...
