I purchase a All-Pro SPC_54 patio heater this summer. Used it once during the summer without any problem. I tried to turned it on this October, but would not work. The pilot would light, but when the control knob was release after 1 or 2 minutes, the pilot light would go out. When I opened up the assembly, the pilot light seemed weak and I also noticed a flame coming out from the pilot air inlet opening. The flame was blue and yellow, and it never seemed to get close to the sensor next to it. My wife and I really want to use it this fall....please help. Thanks

Hi ColdinSF,
You need to remove the covers from the unit and blow out the gas lines with compressed air. If you can remove the gas lines blow out the lines and what they connect to like the pilot light and main feed line to the burner. Usually they gunk up with use and just need to be blown out with compressed air to clear the lines again. Maybe you have some dirt or foreign object from your gas tank which has clogged the line. Also check the igniter electric lines as well and make sure everything is connected properly. Especially make sure you tighten the gas lines you remove. Hope this helps.
Regards
Bryan

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)

I would change the thermocouple and here is why:
The thermocouple is the pilot's, well, co-pilot! It is the electronic device that senses if the pilot flame is hot enough to sustain burning the gas fuel from the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.
How the Thermocouple Works
So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close.
Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat). If the pilot goes out, then the thermocouple gets cold and produces no electric signal to open the gas valve's solenoid and the gas valve shuts off the gas supply to the pilot and burners

you got to be more specific, have you put it together yet? if so, make sure you have the fuel connected right. insure the connector is all the way and tight, incide the valve is a safety divise that if it is not putched all the way in, the valve wouldn't open.
