    I have a cxu613 with no wiring diagrams I do not have high speed on the fan and on speed 3 will work fine for awhile then will not blow but hear the fan spinning it has a new resistor and control panel (fell apart trying to unplug it for testing). Got really pissed off put it back together and pulled it out. Has anyone else had this issue?
