Patio heater won't stay lit

Our patio heater lights and starts heating up, but after 1 -3 minutes it shuts down. The tank is full of propane. Nexgrill Outdoor Patio Heater Model 920-0010 bought at Costco Talking with Nexgrill tech. dept. as I am writing this.  My problem is similar in that after having the pilot light lit for a minute and then turn the control knob to fire up the burners, the pilot light fades away and then the burners shut off. They suggest it may be the thermocoupling.  The best way, they say, to check to see if it may be defective is to unscrew the thermocoupling from the lower cone cylinder and hold a lighter to the thermocoupler while you turn on the burner (of course you should probably have a lighter for both the burner and the thermocoupler).  The thermocoupler should sense the heat and therefore keep the flow of propane going to the main burner.  If the main burners shut off, most likely the thermocoupler is bad.  I have had great success with Nexgrill's tech. dept.  They are very helpful, keep a good log of your discussions and send out the parts you need, even if you are past the one year warranty period.  I like the Heater but find that any propane device is fraught with issues such as corrosion, leaks, thermocouplers going bad and of course, air not purged from tanks!  Pain in the A----!! Good luck!

SOURCE: Lots of yellow - then very low heat

Are the flames still yellow? If so the burner just needs to be adjusted which is very easy? Look at the ends of the tubes that come out of the burner and end right at the back of the gas controls. You should see a small piece of metal that will slide or spin to close a hole. You want to close or open it a little at a time while the grill is burning. Adjust this until you only see blue flame or blue flames with a little bit of a yellow tip.

SOURCE: Just bought new propane tank for my Charbroil

Either you got short changes on gas or the regulator is not working properly. Check the tank to see if it is empty, if not then the regulator will need to be changed.

SOURCE: new propane tank won't ignite

The regulator on the on the hose is either gone bad, or could have got a little bit of dirt in it. You could tap the side of the regulator gently and sometimes this will solve it.

My char-broil patio grill doesn't get any propane to the burner. The tank is full only used the grill 4 times #07601295

Hello. The problem you are having indicates that you have to go through a procedure called "RESETTING THE REGULATOR". Turn the burners on for a minute and then off with the regulator and hose off the tank, then hook it back up and very slowly oven the tank. Then fire off the burners.

In the future, always turn the tank valve on s-l-o-w-l-y to prevent this problem.. Joe

Nexgrill Won't Stay Lit

Is this a patio heater or a grill? In either case, the first thing to replace is the regulator. If that doesn't work, I need to know if it is a grill or heater.
