My boiler is not working, after one repairman who swore blind it was the central heating pump (yes really) and one who would not fix it but now only did new installs (at £3000) I have run out of people willing to come to my rural location and am looking at the unit myself.
The issue is with the fan, it appears to be binding and stopping the heating from starting, if I free it up then I can sometimes get the heating kicking in for a while before it locks out again.
What I can't seem to work out is how to actually remove the fan blade bit from the motor spindle. I have noted that there is a grub screw which I have removed but I still can't seem to pull the fan free and don't want to force it without checking first.
Basically I want to see what is behind it since I suspect that some sort of bearing has failed.
Anyone any hints on removing the blade part?
In case it matters the unit is for a 110/150 sized boiler.
Any hints on part numbers and where is best to order new parts from would also be appreciated.
