Hi, If the pilot light goes out when you turn the gas knob to full power on lighting them the most likely cause will be a worn thermocouple, these usually last between 2 years up to 6 years. Found this site very helpful, patio heater problem solving. They have a few solutions to checking patio heaters.

The thermocouple is a safety for the gas valve. It tells it the pilot light is lit. If your pilot light is not going out and the burner fires when you turn up the thermostat, it is all working as it should. In other words, if you don't need to re-light the pilot, your thermocouple is OK. Turning up the temperature of the water is a good idea, just be careful not to burn anyone with the hotter water. You mite want to try a water saver shower head. Some don't throw enough water to get the soap off, but I bought one that can be turned to adjust flow and we have been happy with it. If I missed what you need from this, please let me know. Roger

Hi, follow what I say and it is very easy. The knob that says off, on, and pilot, is where you need to start. You don't want to turn it off now, as its been off for awhile now. Turn the knob slowly pushing down on it until you fill it go down. The knob will go down believe me. When this happens, keep holding it down as this is what starts the gas to the pilot which is back under the burner, under it. Just take a flash light and you can follow the aluminum tubing back and where it stops is where you light it with something long with a match in it or a small rolled up paper. Keep the knob down the whole time you are lighting it. When it lights, keep the knob pushed down for about another minute. Then slowly release the knob and the pilot should stay on. Once you have it on, turn the knob to on, not off. If you turn it the wrong way, it will go off and you will need to start over again. Once it stays on by itself, turn your thermostat up for heat and the burner will light and come on. Just remember that the pilot where you light it is where the tubing goes back under it, as the pilot gas goes through it. You will need a light. Look at the knob with a good light and it will tell you which way to turn it. In the pilot position, the knob will press down to let the pilot gas in, and you can reach back and light it. Then turn knob on. Pilot should stay light. Turn on thermostat and it will fire up. Let me know how it goes. You may have to try a couple of times.

Your thermo Coupling is bad replace it and you should be good to go!

There is a part under the knob that adjusts from bare floor to carpet that goes bad on these vacuums. I have an animal that is about 3 or 4 years old and I had it repaired last year( to the tune of $115.00), and it broke again in December, so I just bought a new one, tired of paying high repair cost!!

replace the thermocouple. it is a small copper tube that screws into the gas valve and goes to the pilot assembly. a good haedware store that sells heaters will have one. they come in various lengths 18"-48".

I'll give this a go! With a cooker like this, you depress and then turn the control knob, press the ignition button and continue to depress the control knob for a few seconds. This is because a device called a thermocouple is heated by the flame and you have to continue to depress the control knob so that sufficient gas flows to heat up the thermocouple. If the thermocouple does not get hot or stay hot then the gas valve is automatically closed - stopping the gas. The thermocouple is a 'flame failure' safety device. If the gas gets cut off then the flame goes out and the thermocouple goes cold switching off the gas valve automatically. However, you are having to try and manually keep the gas going for a good five minutes. I would think that there is either a problem with the thermocouple or the gas control valve!
