Carrier alpha AI25H

Anyone know the thermistor readings for this split system?
Got a unit that won't run the outdoor fan in heat mode (starts up for a second at first, then off)
Fan runs in cool mode, only a single speed fan. So it's either PCB fault or thermistor off somewhere, thermistors both 13kohm indoor and 40kohm outdoor.

Yeah, no domestic splits there, just bigger stuff. I found some place ages ago, but I think it was US models so impossible to work out equivalence. (I don't come running straight to RE ya know :) At it's best it takes days/weeks for someone who may know to get online, so not good business practice ;) )
