I have a fujitsu ducted unit which seems to be quite old, The problem is the fan for the indoor unit runs constently until you turn it off at the circuit breaker, turn the circuit breaker back on and the fan runs again. It is getting constent power from some where, I have replaced the pcb but that does not change anything. If I pull the supply to the pcb it will stop. Could it be a bad pcb replacement or the fan motor cap?I have pulled the cover off the unit to look at the fan motor and I can see that some windings are burnt, could this have anything to do with it any thoughts would be helpful.
