Its last service was in 2011.
The main burner flames look good to me.


What colour is the main burner flame? Mainly blue? Mainly yellow/orange?

Mainly blue. Can't see the top of the flame though.

When I had this problem, the flame on mine was a normal colour. Only very
small.

Size matters
Mine was clearly too small and being sucked away from the thermocouple
when the main burner started. Then the thermocouple cooled down after a
while, and then the whole thing shut off.
My flame is much bigger now after the gas man blew through it.
It's still working two days later - touch wood.
