Gas pation heater won't stay lit.

When I light my patio heater, it lites fine but the pilot flames stays very high and after about 5 minutes it shuts off.  It lites right back up but does the same thing.  I have a second unit and the only thing I can see is on the working unit once the unit lites, the pilot flame is not high like it is on the problem unit.  
Any suggestions?

SOURCE: Patio Heater pilot lights won't stay lit

crappy pilot flame (not properly heating the thermocouple), bad thermocouple, thermocouple loose where it screws into the pilot safety valve, bad safety valve magnet.

One or more of those is the problem.

Oh...there is also a saftey switch...in case it tips over. It will also cause the pilot to not stay lit (if the switch or wires that go to i are faulty)

Pilot lite won't stay lit


Thermostat flame sensor. Do you see a little rod next to the pilot? That is what tells the main gas valve that the pilot is lit and it is safe to give gas. Easy swap, and you can usually just pick up a generic one.

My pilot light wont light and my heater will not stay on.The ignitor is cliking as if it works but will not ignite and if I manually light it the lighter will not stay on.


Essentially all gas devices regardless of which gas used, are equipped with a thermocouple that monitors the pilot light's condition and if it fails, it will not permit the main flame to light or the pilot light to stay lit. In your case, it may be that the TC failure also prevents the lighting of the pilot light.

My heater lights but then does not stay lit (goes out after about 30 seconds). Any suggestions??


Sounds like the thermocouple is failed or really dirty with soote. When the flame lights and the thermocouple is in touch with the flame...it will create a minute amount of electricity which is sensed by the controler of the system. If it does not sense the flame then it will time out and shut off the gas supply regulator valve and pilot tube!

All of a sudden my patio heater will not stay lit.


Describe the pilot. Is it a strong blue flame or lazy yellow? Is the thermocouple getting red hot by the pilot flame? I'm wondering if the pilot is impinging enough on the thermocouple to keep it lit. It may be dirty, so try blowing out the pilot orifice with a can of compressed air and see if that helps. Also make sure the thermocouple tip is not burn't. If you feel the tip and it feels jagged, then replace it. Hope that helps. Douglas

Pilot will not stay lit and heater will not light


thermocouple probablly bad, is the flame covering the thermocouple.
the flame has to hit top portion of thermocouple to work correctlly.

Pilot lites; but, as soon as I turn on gas flame


sounds like your thermacouplar is going out and needs replaced. Sometimes these will act like they are working fine , but when the pilot stays on for awhile and later goes out it is a sure sign that it is bad

Kirkland outdoor heater will not stay lit


The thermocouple is bad. That is the part right next to the pilot light that sense's the flame and hold the gas valve open to the pilot. Take the old thermocouple off and go to hard ware store and get a 18" one of what ever length you need and replace. 5 dollar part.
