Hi Hugh and thanks for responding.
Yes radiators upstairs are hot and its freezing downstairs although I have not turned boiler off for a couple of days cos I am soo scared of it packing in again.
I have been sitting watching it today and it literally goes off every five minutes then...
Can somebody please give me some advice before I waste any more money unless it is absolutely necessary!
I have a baxi solo 2pf which started to play up before christtmas. Had 2 guys out ..one said PCB and the other said it wasnt ..it was the fan.!
Went with the fan because I am a female...
