Unreliable gas cooker

[Easy-X]

I have this Zanussi that's a few years old and as far as I can make out (not knowing much about gas appliances) the hob works on a system of heating an electrical thermocouple and if the flame went out the supply to that ring would be cut off. Sounds like a sensible safety feature...

After a couple of years the rings just wouldn't light. I discovered heating the thermocouples manually with something like a pocket butane torch would "start off" the process and the ring would remain lit. Over time this just got worse until I replaced all the thermocouples with new ones.

Now it's doing the same thing again Do these thermocouples only last a few years or do I just have a crap cooker?

I think you have a crap cooker or there is something wrong with the placement of the thermal cutouts, I've never had one go wrong on a gas cooker. Maybe they are too near the flame and become damaged over time?

*Edit: or not near enough to the flame and not getting hot enough.

Mine does that.
Didn't know you could replace the rings!

Are the thermocouples heated by the flame?
Maybe the flame isn't hitting the thermocouples.

Appliance of Science was only a marketing ploy.

Dodgy this and dodgy that on a gas cooker?
Hmmm? Not good.

Surely there has to be a time to get a new one?
Or will there be a thread on here?, “did you hear about Mr Easy X ?”
“His house was destroyed in a gas explosion because of a dodgy cooker”

I’d be inclined not to muck about with a gas cooker or mains gas as I’m not an expert.

Just my .
