When trying to fire up my patio heater the pilot light lights but goes out when trying to turn gas supply knob to either high or low heat. Is there a way to find out if the thermocouple is shot. It has been cleaned, used compressed air.
The pilot's millivolt generator may be at fault. if you have a meter that is capable of measuring a very small DC voltage, connect it up to the very end of the thermocouple and the copper cappillary. the thermocouple has a welded bead at the very end inside that generates a small DC voltage. Same principle of a J-K thermocouple. Iron constintan - two dissimiller metals where joined together produce a voltage when heated. the thermocouple actuates a millivolt electromagnet inside the valve to keep the valve pellet open. no voltage there it won't actuate the electromagnet.

The pilot light is on but the heater will not come on. We have a programmable thermostat and it shows temp etc.

This is the most common question and issue around these heaters. The Pilot Assembly needs to be cleaned out. See steps 7 through 14 here.

If this has done it from day 1 make sure the thermocouple is tight in the back of the valve. It is very common for it to become loose during shipping. Unfortunately you can't just buy the thermocouple for the Endless Summer of Blue Rhino. You have to order the complete pilot assy.

I dissasembled the main gas valve/regulator and think my thermocouple is not holding open the plunger after the pilot is lit. Any suggestions?
I have a similar problem. I turn the **** and press it. The ignitor works and the pilot lights up but does not stay lit. I have to try this several times (15/20 times). Sometimes it does not light up at all. It's done this from day one so cleaning the venturi is not an issue. Am I doing something wrong?
