On Thai set ups you will more than likely find the air control is a small leaver behind the tap. Just turn it one way and then the other and you'll find it will come back to life. Leave poking things in the holes alone, unless you have a blockage in one of them. They have more than likely got turned off/down when the thing was cleaned. That's if it ever was. Whatever they can be turned down very easily. Tip you can see the valve if you lift the front of the hob up. Once found put it back to normal position light up and twiddle with the valve. It's never been cleaned!! Link to comment Share on other sites More sharing options...

I used to have gas stoves and I know the problem well. Just lift the tops off, give them a good soak and then clear the jets with any convenient poking thing like a bit of wire. Nothing to it. I used a drill bit of the same size as the hole. Scrapes the dirt off better than a piece of wire. Not always dirt though. A very expensive stove never burnt right for me, even when brand new.

whaleboneman Posted July 26, 2019 Share Posted July 26, 2019 It's dirty, ring is upside down, and air needs to be adjusted. You will have to buy a brand new house - it will come with a brand new cooktop. 1 Link to comment Share on other sites More sharing options...

Had it happen several time on my set up when the Wife cleans the top it sit's on and has mover the leaver that adjusts the mixture with a cloth. She now knows how to fix it so I don't have to go near any of our 6 burners now. Edited July 26, 2019 by fredob43 1 Link to comment Share on other sites More sharing options...
DJ54 Posted July 26, 2019 Share Posted July 26, 2019 Now we wait for the OP to let us know how it was fixed.... FNL told me we were out of fuel for the stove... went out and opened the valve.....it worked. Link to comment Share on other sites More sharing options...

As noted above check the jet which will be near the control tap and the air inlet which should be near the jet. The mixer tube may be clogged too. Taking the whole thing apart and cleaning will likely return it to operation. Exactly, a yellow flame means insufficient air and in this case virtually no air at all. Your suggestion would certainly be a good starting point. If it was merely the holes on the burner blocked then what flame that was there would be blue, and roaring like a bunsen burner. Personally I think there is a pressure problem, the gas comes through a small jet and needs velocity to suck air into the mix. The most obvious cause would be the bottle nearly empty but it could be a bad setup, a mismatch between gas and regulator or jet. In the UK Butane is 38mbar and Propane is 50mbar but the connections are such the bottles and regulators cannot be interchanged but I have seen a similar problem when a Propane cooker has been installed on a Butane supply and from what I have seen anything seems to go in Thailand. In a previous life I used to design gas cookers for caravans. Link to comment Share on other sites More sharing options...

That will fix the problem. Spot on, except in this case the gas pressure is just too low. The gas/air mixture butterfly only needs adjustment if the gas type changes. It's also very unlikely that the burners are clogged so badly as others have suggested. Link to comment Share on other sites More sharing options...

samuttodd Posted July 26, 2019 Share Posted July 26, 2019 Take the top element off the assembly and clean all of the crud off with rubbing alcohol or acetone. Take a wire and clear all of the holes where gas is supposed to come out. Give it some time to fully evaporate and dry before you try to run it again.

I had a double gas hob arrive in the post like the OP, one burner worked, the other was yellow. On some of the designs it's easy to shift the shutters as you move them around. Probably someone wiping it down knocked it out of adjustment. But doesn't really matter what the cause, the shutters can probably fix it.

They can't compensate for low gas pressure. Closing the shutters will decrease the air to mix properly with the lowered gas flow, but the flames will still be weak, as in the OP pictures. That's why I doubted that the shutters were the correct solution. Can't hurt to experiment though. Link to comment Share on other sites More sharing options...
zappalot Posted July 27, 2019 Author Share Posted July 27, 2019 since the stove is on our terrace where it gets wet during rain I guess that rust is the main problem. It is not really dirty. I tried to clean everything a bit but not much result. Why should the pressure be a problem? Have used several bottles of gas and never had a problem. When the gas was finished it just stopped working instantly. It always worked until the last second So finally I ordered a new gas stove for just 360 baht Link to comment Share on other sites More sharing options...
