I am looking for the users manual and warranty information for my Jenn-Air 720-0163. While this is the worst grill that I have ever owned, I wanted to try to fix it before throwing it in the trash and spending another $500.

If you're confident that you have adequate gas in the tank. turn the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Once connected, open the tank valve VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, light the burner farthest from the tank first and turn it to it's highest setting. Does the flame height look correct? If so, light the remaining burners the same way. Do all the flame heights now look correct? If so, you solved the problem. Remember to always open the tank valve very, very slowly.
If the above didn't solve the problem, you are either low on gas or the hose/regulator assembly needs to be replaced. If replacement is necessary, you can find the hose/regulator assembly at any home center or hardware store that sells gas grills and accessories. Take your old one with you for comparison purposes.
Hope this helped you solve the problem. Happy Grilling!!
Burners are clogged or defective and the flame is "backing up" which may have damaged your gas valves and/or ignitor. Try removing and cleaning the burners with a wire brush or if under warranty, have nexgrill replace them all.
The crossover for the flame to "jump" to the other side of the burner is clogged, rusgted, etc. It looks like a straight cut line on the rear under side of the burner. Nexgrill told me that the burners did not have an adequate amount of "finish" on them. Call them and get all new burners for free under warranty, Since 2004, I am on my 5th set of burners.
This seems to be a problem for most Jenn-Air users. The burners are defective, rusted or clogged and allowing the flame to "back up." You most likely have a melted electronic ignitor as well as gas valve damage. The new burners that I received this week for my model 720-0061-LP are 1/2 inch shorter than previous versions. Time will tell if this fixed the problem. I would call Nexgrill and get all new burners and inspect the gas valve area for damage. Since 2004, I am on my 5th set of burners, glad they were free since I have a lifetime warranty on my model.
I broke the same part when trying to manually turn the shaft on a stuck motor. That part is made out of pot/white metal. Mine broke at the base where it slides onto the half round shaft on the motor. I was able to fix it by drilling a small hole in the half round shaft on the motor and the broken piece. Then I used a small finish nail as a pin to hold the two parts together. Next time I take it apart, I will use some JB Weld epoxy on it. I don't think you'll find that piece by itself. I might just tinker on my metal lathe and make one up, but looking on ebay is probably your best bet for the whole motor.
You should test the wiring to see if there is any short that is causing the overheating. If one knob only is getting hot, then the knob is probably faulty and need to be replaced.
I the all knobs are overheating because of heat coming from the grill, then is a bad heat insulation problem, better to call the service number listed on the owner manual and discuss the problem with Jenn Air in this case.
