2 weeks agoI replaced my burnt PCB for a reconditioned one.
Today I have lost both CHW and DHW because the mains LED is off. Mains power is on and the Fuse F1 is OK. According to the Fault Finder I should..."remove Plug PL6 from Modulator Board, Are Both Transformer Windings Closed Circuit? If Yes replace PCB if Not Replace Transformer Assembly." Does anybody know what "Transformer Windings Closed Circuit " means and how do I check it.
