Patio Heater pilot lights won't stay lit

I read this thread and I can light my patio heater but the pilot light will not stay lit after the on/pilot/med/high know is un-depressed. I put the knob on med or high with a lighted flame where the pilot light is and nothing happens. Any ideas?

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)

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.

Pilot light won't stay lit when I let go of the igniter knob. Flame is yellow and long.


Sounds like the Thermocouple has failed and needs to be replaced. It's not difficult to do. But, finding the part may be. Blue Rhino, is the manufacturer for Endless Summer Patio Heaters, so start there.

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.

Outdoor patio heater won't stay lit


I'm told by Charmglow that the problem is the Thermocouple. iHowever,it took me several calls to get someone to admit this. They are sending a new thermocoupler. My heater is less than a year old and under warranty--but it's a shame things like this happen.

Originally I was told it could'nt be the thermocoupler as they normally last at least 5 years.

Try it--as it may solve your problem as well.
