Fridge Gas Ignition issue.
I am not new to 3 way fridge on gas problems but this one different for me.
Brief introduction, RM6401L (old!).
Burner assembly changed 2 years ago and chimney swept! All well.
Recently would not light on gas, burner removed and blockage of jet remove with compressed air.
Now lights on gas and stays lit after release of knob.
So far so good.
However the ignition continues without ceasing. Now I believe the thermocouple current holds the gas valve open, which it does, BUT why does the ignition continue? The thermocouple is obviously giving an output to the gas valve.
Does anyone know how the igniter is designed to know that the burner is lit and therefore cease?
Attached is a diagram that I worked on the last time I was wrestling with the fridge. At that time I commented that I could not see how the ignition ceased.
Any advice gratefully received.
