Hi guys first time poster( hi all)

Got a slight problem with a General Electrics (GE) air conditioning unit AS0Ah12. Went on a call out today, the owner had reported that her unit had stop working. After a bit of fault finding I found out that when the unit was switch on the air handler was working but the outdoor unit was not. There was power going to the air handler from the main supply (a plug system) but no supply was going to the compressor. After more fault finding and playing around no power was coming down the cable between the indoor unit and the outdoor. To see if it was a possible board or switch fault I gave the outdoor unit a permanent live and all worked well. However the problem I now face is I cant get a board from anywhere in the UK bloody GE I have spoken to HRP and a GE supplier but they cannot help I have looked on the unit to see if I can wire from the power supply to the air handler which can be turned off but at the moment I face the problem that the indoor unit can be switch off via the remote but the outdoor unit is on permanent.
Can anyone suggest anything as im having a bit of a blonde moment? The owner doesn’t want to buy a new unit even though I have explained it could be costly and the unit is an old system (R22) there must be away to put an switch able feed????
Help

Kind regards in advance
