Glow-worm fuel saver 80 F cut out problems

[The Trout Catcher]

Help I have just moved into a new house that has a Glow-worm Fuel Saver 80 F. the boiler lights up fine and then runs for about 30 – 40 seconds and then shuts down for about 30-40 seconds and continues like this, any ideas?

Check the pump is running, is the boiler stat on full?

could be aps

Hi and thanks for your response, I’m sure the pump (Granfos) is running and the boiler stat is on full. I have a spare pump as this one is set on position 3 as it makes a noise when set on position 2, could that be the answer then?

Sorry but what is aps?

SORRY air pressure switch. THINK it a large white plastic one near gas valve on that boiler. or could be a blockage in the venturi on the fan.

I would be fairly sure that your problem is the fan, which overheats causing a resettable thermal fuse attached to the winding to open and cut out

If this is the case, please acknowledge that this was the problem, then they will know better next time

Many thanks for your response, if it is the fan as you say, is it easy to fix do you think?

As Raden says, this sounds like the fan as I had the same trouble a few years back. I fitted a recon unit which cost £25. It's an easy fix if you are reasonably mechanically-minded. What is your experience?

 

[The Trout Catcher]

Thanks Paulie, i can tackle most things and have an engineering back ground so should be ok to do this. Do you remember what part it was.

I have noticed that none of the 'experts' on here have commented on Radens comments.

Is this because he is probably right AGAIN.

Is it really a resettable thermal fuse?

All the ones I have ever found in fans have been a one shot fuse!

both exist

.. but there are a significant number of fans with resettable thermal fuses out there - and it confuses a significant number of CORGIs because they are not aware of the fact
