After being in storage my patio heater will not light. The igniter is not working but that is a separate problem. I can detect gas flow through the regulator and hose up to the gas control valve but there it stops. I suspect the gas control valve is not working because when I take off the fitting on the downstream side and turn the control to ignite or on, no gas comes out. Do these controls stop working for no apparent reason?

I had the same problem and fixed it with a small piece of Aluminum foil, an adjustable wrench, and a #2 screwdriver... If you're "handy", this is an easy 30 minute fix. I included a picture that may help you visualize the "fix" before attempting. In short, I'm not certain what happened or why/how it broke, but if you remove the valve/manifold you can blow air into the gas inlet (with your mouth) and adjust the knob and you will see that only when it's all the way pushed down you can blow air through the valve, otherwise n air/gas can not get through. Thats why the pilot will light, and when you let the knob out the flame goes out. If that is your problem, this fix will work. After I put the foil (explained below) to extend the brass pushrod that allows gas to enter the manifold, it worked as expected allowing air/gas to enter only when on "light" and through the LO to High sweep.
Step 1) Shut off gas and remove tank.
Step 2) Remove the black gas On/Off knob (pulls off)
Step 3) Remove the three on thumb screws inside the tank storage area to allow the entire top/heater mesh to slide down (like intended to store it, or how it came shipped in the box). Sliding this down will expose the bracket the manifold/valve mounts to.
Step 4) Remove the spring clip and washers from the stem on the valve. Remember the order, and dont lose any parts as this works your igniter. (I usually take a picture with my phone on these types of things, so I can recall how they went.)
Step 5) Carefully remove all the gas lines from the valve and the grounding wire at the rear of the manifold.
Step 6) Remove the two small Phillips screws that hold the valve to the bracket.
Step 7) Remove the valve from the unit.
Step 8) Remove the two small #2 Phillips screws that hold the aluminum and the brass parts together on the valve.
Step 9) Give a slight tug and the two pieces will come apart easily. A small aluminum part may fall out; this is okay as it only goes in one way.
Step 10) Take a small piece of aluminum foil 1 1/2 inches by 7 inches or so, and wadd it tight into a ball. I used pliers to get it tight and small (bigger than BB, but smaller than the end of a pencil eraser) You will see that it needs to go inside the channel where the brass stem will slide in and out of the "slotted" tube on the stem.
Step 11) Put it back together and try the "blow test" again to see if the aluminum ball was the right size to make it work ...again. I had to do this a few times to get the right size "extension". Also, be sure to blow into the "main" gas inlet and adjust the gas control knob through the push in and "light" the pilot mode all through the Hi/Lo sweep.
Reverse your steps and give it a try. Mine lights every time and works perfect. ...actually better than new, as it was always a task to light.
Hope this was helpful, as this was my first post...

More than likely it is a bad thermocoupler. The thermocoupler is that pointed piece that receives the shock when pressing the ignite knob. You will have to take the unit apart to get to it. It is the pointed part with stiff wire attached that is between the shock electrode and the pilot light. It could also be the magnetic valve at the base of your control knob, but I doubt it. It could also be the tip switch which you can test with a simple continuity bulb or tester. The tip switch is wired inline between the thermocoupler and the control valve and knob assembly. It is about nickle size and has 2 wires attached to it. You can test the magnetic valve by removing it from bottom or base of the control knob and touch one end of it on a AA battery and the other end of it jumper to the opposite end of the same battery while depressing the spring at the same time. If the magnetic switch is working you will feel the magnets attract until you pull the battery or jumper wire away disrupting the connection. There is also a way to measure the resistance of the thermocouple but if you have tested the other two items you can bank that the thermocoupler is bad. Before and after make sure you don't have any leaks by using a soapy water in a spray bottle at all of the gas connections as per the owners manual.

these had problems with purging air out of the system.that may take a while and make sure you have spark.
