Boiler burner light (green) keeps going out HELP

[liam546]

The green indicator light for my burner on my Greenstar Ri boiler keeps going out after I switch on the central heating.

I have balanced all my radiators, bled all air from them, set my thermostat to a required temperature but each time I switch the heating on the burner indicator light initially lights up green but after 5 mins or so the burner and therefore the light go off.

Any suggestions would be much appreciated.

Boiler is over heat. Check the pump.

Are the radiator valves all open?

Do they all get hot?

Thank you for your replies....since my post I have found one radiator that wasn't heating up. The lock shield valve was fully open but when I removed the TVR valve and tapped the stick bit the hot water started coming through. I skso checked the pump and it seems to be running ok. Since I have sorted this last rad and completely bled all the air out it seems to have settled down and has been running for a few hours now. Do you think the system just needed settling down?

Yes!
