We have this boiler: Potterton Netaheat 16-22 (Mk IIF).
Everything was working fine yesterday. The boiler has not been used at all since last year until yesterday as we were away.
Today the fuse blew when we turned it on - and replacement 1 amp fuses are blowing whenever it tries to start up.
The relay clicks, the fan whirrs briefly and then the fuse blows.
I had a poke around at the electrics and with the fan disconnected from the PCB (and everything else connected as usual) the fuse doesn't blow. If the fan stays connected and everything else is removed then the fuse blows. The fan does sound like its working for a second when its trying to start though.
I guess its something in its startup sequence that is broken but I dont know what.
Is this something I can work out myself or is it a case of calling someone in. I'm happy to turn the power off, change / replace a bit and turn it back on - but I dont want to touch anything that involves leaking gas etc.
The relay is new (last year) but everything else looks rather mid eighties I'd guess! I'm not keen on replacing the whole boiler right now and need it to work asap.
Can anyone help or recomend a plumber that would know in High Wycombe?
Thanks
Ant
