Wow.

Astonishing people here, are encouraging DIY boiler fan replacement.

Having dealt with CO poisonings were basic checks were incorrectly or not carried out I do wonder.

All seemed to go back together ok though replacement fan electrical connections weren't exactly in the same position, but clicked on ok.

I suspect this is your problem. But...

Why mess about with gas? You've just proved yourself incompetent by asking for help on here.

Good luck trying to find someone that will fix it for you.

Hi all,

...Two odd things i noticed , first the fan I was sent as the model replacement has it as a 33W on the label but the one I removed has 45W.

Second, the little black tab that electrical connections were on seemed to be on a flexible hinge which seemed a bit odd...

Where did you buy the replacement fan from?

A genuine replacement from Wolseley is £270. Aftermarket fans on ebay are £50.

DIY gas work???? Not something I would be encouraging.

Now you have the original fan off, you can replace the bearings for £5 ebay items.

Changed my FF250 fan back in Feb 2017 using this one from Amazon.

It was cheaper to replace the fan than the whole boiler in my case, still going strong to 2 years on, even though the boiler was installed back in 1999.

I remember is was easier to trim 10mm of an existing phillips bit, so it could fit under the exhaust vent, for the connectors, I just had to make a sent of 50mm extension leads to fit on to the connectors without being stretched.

OP have to tried reversing the motor connections to see if that fixes the issue ? Otherwise sounds like you may have a issue with the pressure switch or the hoses connecting the fan to it.

Check that the motor actually works by disconnecting it and sticking 230V mains across it. It doesn't matter which way round live and neutral are - it can only spin in one direction.

Be careful

Aps tubes won’t stop the fan running.

Far easier to just test the voltage at the fan rather than trying to introduce a test voltage

If you don’t have a test meter you shouldn’t really be in there

A tripped OH thermostat will prevent the fan from running. You are looking for a protruding red button on right side of control box cover....if it pushes in with a “click” you should be ok (ish).
