HI there,
I have a problem with a Gloworm 50ff that perhaps someone can help me with.
My boiler will fire up and run for around 10-15 mins all my radiaters get hot, then even though the room thermostat and the thermostat on the boiler is calling for heat the boiler cuts out. After 5-10 mins the boiler re-ignites and runs for 5 minutes goes out again.
Radiators have all been bled a little air comes out one radiater but other than that it seems fine. I suspected that the boiler was over heating and cutting out? Opening the centre screw of the pump show there is water there and that it's spinning. I've just opened the control box and when the boiler is running normally, both the boiler and the room thermostsat will switch the boiler on and off as i turn them up and down so I think they're alright.
When the boiler cuts out all four neons switch off just the same as if the room stat had switched it off, but the test above suggests that the stats are ok.
Can anyone shed some light on this? Suggest further tests? Other than the stats what could switch the boiler off Air switch? Over temp cutt out?
Thanks in advance for any assistance you can offer
