Possibly faulty thermocouples, a few tips here.....

Take care, don’t mess with gas, perhaps get expert advice.

Silly question, but I will ask anyway;

You are, of course, holding the knob in for a number of seconds after it lights aren't you ?

I know it takes a few seconds for the thermocouple to warm up, I have to say I have never looked for it, but surely, it has to be where the heat will get to it ? So OUGHT to be visible, but I don't know where it is for each burner.

My thoughts are that "energetic" cleaning may have moved them a touch, not a lot, but enough to move it out of line.

Like Terry, I would NOT advocate playing around in a DIY manner with gas, the potential consequences are horrendous and I am very much safety orientated (belt, braces AND a piece of thick rope to hold up trousers - just in case).

I believe that even "normal" gas fitters are not permitted to work on MH supplies, the GasSafe register requires an extra LPG module, I think.

But, lifting the burner as for cleaning, may show where the problem lies by comparing all three., can't do any harm (says he with fingers, arms, legs, toes AND eyes crossed).

Warning; no responsibility accepted for any ensuing carnage if my advice is, like a lot of what I post, a total load of manure from male cattle. 💩

Try lifting the kettle/pan up, away from the flames before you let go of the knob. I used to have to do that with my previous MH. I don't know if it just needed a bit more air or what but it worked!

I always remember hearing a distinct 'click' 20 seconds after turning the gas off after boiling a kettle when the thermocouple or bi metal strip opened to stop the gas.

Firstly check that the flame fan cap is not clogged. Then there are two little pips around the burner. One is the spark which will be pretty obvious, the other is the thermocouple (TC). Hold a lighter on the TC tip when you release the gas control knob. If the gas stays alight then the TC is working ok, as has been stated may have been moved when cleaning. You can gently move the TC towards the flame. If the gas does not stay lit then it is possible that the spade connectors to the TC are corroded, simple job to pull off, clean the spades with wire wool & replace. These are prone to corrosion, they are also in the most awkward place imaginable. It is possible to test the TC by connecting a meter across the TC terminals & holding a lighter against the tip of the TC, a small voltage should be seen. If all this fails then you are probably looking at a new TC but beware they are stupidly expensive.

Perhaps one of these will help explain it to others.
Got myself one from Amazon recently.
