I have a Kenmore 14116329 propane grill. The propane tank is full but when I turn on the burners very little gas comes out resulting in a VERY low flame. Is it the regulator or???

Turn off propane. Disconnect propane tank from barbecue. Open burner valves for about 20 seconds. Close valves. Reattach propane tank. Slowly open propane tank valve. Turn on burner and ignite

Check there is gas at the burners and that the orfices are not block or the burners are bot blocked .

Turn on burners let pressure out of line turn off tank remove gas line then reconnect to tank and turn on tank slowly see if this works

Turn off the propane tank and disconnect the hose from the tank. Wait 5 minutes, reconnect the hose and turn the tank valve on very, very slowly, until it's completely open.

Now light each burner one a time and turn it to high. If the burners all light and the flames remain burning on high for more than a few minutes, you're back in business. Just remember to turn the tank valve on very, very slowly after turning it off each time.

If the above didn't solve the problem, are you sure you tank gas a significant amount of gas in it?
If that's the case (empty tank), when you replace it, do exactly what I said above when you connect a full tank to the grill hose.

Hope that solved your problem. Happy Grilling!

check the burners are not blocked and the orffice , check the reg on the tank giving full pressure

check burners are not bolcked check orffice is not blocked also check reg is giving right pressure

Problem: Low flames on grill, tank is full.

Cause: These newer tanks have a device inside that limits the flow of gas to prevent leaking or accidental discharge of gas from the cylinder. The leak detector mechanism inside the tank shuts off the gas whenever the valve is opened rapidly.

Solution:
Close the tank valve and remove the tank. Check the gas line for ANY object that could cause blockage. Open all valves on the grill to eliminate any pressure whatsoever. Close all valves and reattach tank. SLOWLY open the tank not over 2 turns. Check for leaks. I just open my tank a tiny bit but that is just me.

This late model gas grill service manual has more details on page 13.

You either have clogged burners and they need to be cleaned. Clogged inlet line to the burners. (This can come from trash, spiderwebs etc in the connection, kinked line etc.) or the regulator is malfunctioning.

Most propane problems are due to a new valve on the top of the tank. It is designed to only allow a minimal flow until the line is pressured. This prevents fire flair up from broken or leaking hoses. Always turn the bottle on and wait before trying to light a burner. If the burner is on first, the propane will never come out at full flow or if you have a leak in the system, it won't pressurize sufficiently to allow full flow out of the bottle. There is never "air" in the tank.

I had this same problem especially when the tank on my 5 burner 2 year-old Kenmore was about half full. The solution above fixed it. I was used to opening the gas fully, turning one burner to high and clicking the button. If I would have read the front of the grill I would have seen that this was incorrect. I turned off the grill completely, unhooked the regulator and reconnected it. With one burner on high I began clicking the button BEFORE I turned on the gas. I slowly turned the gas on one quarter turn and it lit up full flame. I slowly turned the gas another quarter turn and lit the second burner. I slowly opened the gas all the way and lit the third and so on. That did the trick!
