    That’s something that I’m learning. I no longer need to buy my parts from TK, especially maintenance parts. I’ve checked with AutoZone and they do carry some of their maintenance filters.

    Fram XG3593a oil filters are what I use on mine... available at Walmart. Be careful to look in the box before you take it home, buttheads like to switch the cheapo orange filters into the box and put the good one in the cheap box for themselves.

    I think I’ve had enough of this APU. I may have to take it to the TK dealer after all, but at least I learned many things by trying to fix it.

    And I know you said you're done working on it, but I just found this in the manual...

    That means the switch on your drier is not binary. It only performs high pressure cutout. Therefore is likely the cause of the alarm.
