I meant to put gas boiler in the heading not fan .
Hi the fan on our gas boiler seemed to be stuck.
This happened before and we called out a guy to check it out (a qualified gas servicer guy).
I watched him and he used wd40 to free up the fan.that was about a year ago but it stuck again today.
I rang him but he said we need a new fan.
I think hes right but to get the fan up and running again today l have used some wd40 to free up the fan ,I didnt use that much of it and the fan is working again with the boiler back working.
What lm concerned is tho that the inside of the boiler seems to get very hot around were the fan is and as wd40 is flamable is it safe to be using it on a gas boiler fan ?.
