Why do you get them, because you can fix them. Half the time the suppliers will charge you R1000 for a replacement board, even if the fault is a common one, which is that indoor fan capacitor going low in value, so the indoor unit fan will not start up. R5 capacitor and away you go with a working unit again. Reminds me, should stock up on those soon, running low, but Mantech is just 5 minutes down the road.
