Hi I have a 1762-L40BWAR that I use for my central heating. I had a wiring fault which shorted my 24vdc input supply and now wont go, no lights or anything. I got a new one to get my heating going and HWC. I would like to fix my broken one I know the power supply is not working and I found 2 fuses F1 and F2 both are ok. Is there somewhere i could get another power supply board or get this one checked?
