transformer was bolted onto D11 burner case plate with two screw bolts...

Yeah thanks, managed to get all details off old transformer and sourced one as below numbers all the same... Danfoss 052L0003 Transformer 220V Danfoss Product Code: C02024U £46.50 Thanks for yours and everyone else's help... much appreciated(y)(y)

You were spot on oil head....its the transformer which is rogue....with it disconnected its continually going to lockout and fuse not blowing after half dozen attempts.....now to try and source a new transformer...any ideas? 25 year old Part no under worcester spares is JFPJT159X....

Thanks will persevere with your suggestions....

It seems that the pump is showing resistance...but when I disconnect it from the main board the boiler still tripping blowing fuse....even when I disconnect pump and diverter valve....still blowing!!

Ok...new diverter valve fitted 6-8 months ago so will dust off multimeter and refresh myself with checking for shorts....thanks

Boiler....not the missus....

Going to check condition electrodes / leads etc....maybe it's the transformer..old boiler but was going well after new motor and fuel pump....maybe replace with younger model...can't afford new...

My 25 year old worcester heatslave 12/14 starting to blow fuses in plug socket....turn boiler on with new fuse it goes through exhausting chamber but when turning on heat control it blows fuse....new motor and fuel pump fitted 4 months ago....thinking it may be the pcb or high tension electrode...

Hi Lads, It was the capacitor after all..loads of brown stuff leaking from it so replaced and everything good motor fan and firing well... Thanks for all your input.. Great forum. (y)(y)(y)(y)(y)(y)

Yes, absolutely, I bought the heatslave second hand from my Bro when it was 3 yrs old as he needed the bigger model following his extension to his home...he bought it in 1991...changed most parts in burner unit over the years but stilll good boiler and easy to work on.

Ok will test tomorrow when i find my multimeter....blame the wife...... Thanks.

Ok will do.. What's a simple capacitor check? Thanks

Hi, (1994) Selectos D11 burner unit is not pre purging the chamber only making buzzing sound then a click, then after 5 seconds goes into lockout. Thinking may be faulty control unit Satronic TF832.3. Any suggestions....Motor, Capacitor, 1994 model not 1988 Thanks Ian
