Weak flames - no pressure

How to Troubleshoot Gas Grill With Low Flame

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

Turn valve on tank off unscrew nut at valve on tank most are reversed threaded so oppiste direction.

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

Next time you use the grill turn the gas on slowly. For some unknown reason when turned on quickly the regulator reduces the gas flow.
Another problem with some gas fittings is an auto shutoff if detects the slightest leak. Sometimes the shutoff is not 100% and allows a small amount of gas causing the weak flame.

The most common cause of reduced flames is a pressure problem. Could be the gas regulator for the grill. When the burners are on try giving the gas regulator a tap with something hard and see if they change size. If they do then the rqulator could be sticking. And there is a very small hole on the regulator called a vent. If this hole gets plugged with dirt or grease you can get a low pressure problem. Look very carefully on the regulator housing for this small hole and verify that it is clear. Try using a small metal wire(like a tie strap for sandwich bags) to make sure it is clear. Also verify that the tank(if propane) is not overfilled. An overfilled propane tank will cause a pressure problem. You can turn the relief screw on the propane tank until no more liquid comes out to see if this fixes your problem.

If this grill uses the small propane tanks, the regulator in the part that attaches to the tank could be bad.

It is possible that your burners are clogged. Clean the burner ports with a paperclip (not a toothpick).

Low flame, low temperature, yellow flame: This has become the biggest problem with many grills these days and it's almost always because of the regulator (the funny UFO shaped thing on the gas hose). Regulators seem to be stickier these days and when they stick you don't get enough gas to generate a good grilling temperature. To get your regulator unstuck you need to release the pressure on it. Follow these steps exactly:

1. Turn off the gas at the propane tank
2. Disconnect the gas line from the tank
3. Open the grill lid
4. Turn all control valves to high
5. Wait for about a minute
6. Turn all control valves to off
7. Reconnect the gas line to the tank
8. SLOWLY turn on the gas at the tank
9. Light the grill normally
10. Your grill should now heat normally

To keep the regulator from sticking again make sure that you turn off the control valves first, then turn off the tank valve. Always open your tank valve slowly. If this doesn't work give it a second try. If you still have low flame then you probably have a faulty regulator that will need to be replaced.
