Hi = new here and come in desperation for help please.... Old Trianco 28/32 oil boiler playing up and now not igniting. I've spent a samll fortune replacing the time controller and the ignition controller, but still no spark in start up sequence. Relay closes, but burner faults out to reset mode. Heating engineer eventually arrived, stripped down the burner (looks like an Electro Oil International with 0.85x80 nozzle, but no further ident on unit). Engineer identified the lack of ignition was due to fault in the transformer, a May and Christie type ZA 23 100E. He says they are unobtainable now (??), and was clearly not interested in taking repairs further, and rushed off as soon as I'd signed his chit!, but checking on line shows they are still obtainable at highly variable prices. Before I waste another couple of hundred quid on a 30 year old boiler, buying a new transformer, fitiing it and finding I still have no ignition, I wonder if there is any way of verifying that this transformer is stuffed? From what I know of transformers they are usually not repairable. Or perhaps I might substitute another type of lower cost ignition transformer? The M+C transformer is rated at 240 v primary and 2x 5kv eff at 22ma secondary output. Any helpful comments PLEASE.... Driven me to the edge of despair and bloody cold after 10 days with no heat in house
