Hi all,I have just changed a carrier 4 button controler for a 40jx036 ducted unit, we did this cos of a powersurge which took out the pcb as well, so that was changed first, now heres the problem.the con panel lights up but dose not opperate the ac unit, this one runs a 3 wire system (pgc) the new controller has 2 plastic screws at the side but the old one dident , they are tho ideniical to look at, is there difrent controllers that look the same but do not work the same.??Thanks,
