Baby weber flame will not adjust to different levels stays on high flame even when we turn the knob

You will need to replace the control knob assembly. Which includes the tank hook up & regulator. Contact Weber Customer Service @ 1-800-446-1071 for this part.

Hope this helped you.

2 of the 3 knobs on our Weber Grill partially melted also - can this be repaired? Same problem as Josh in a previous request.

Sounds like the gas valves for your burners are leaking, igniting the gas and casing the control panel to get hot and melt the knobs. It can be possibly repaired, but it will involve dismantling the control panel to access the valves and replacing them. You can get the parts directly from Weber.

Weber Natural Gas S450 has worked great for 3 years, now I can't get sufficient heat to cook. I use it maybe 5 days a week. Thanks

I have/had the same problem with my weber q. It will light briefly and then extinquish itself or only fire up partially. One method I have found that works periodically to get it to fire up completely is to start with the regulator control knob in off and open the valve on the tank - slowly - and then let it sit like that for 5 or 10 mins. Apparently this equalizes the pressure in the hose or something. Then try and light it. Sometimes it works sometimes it doesnt. Honestly I want to just leave the the thing in traffic most of the time.

Our weber grill is suddenly getting too hot... even with only 1 of the 3 burners turned on it is over 400 degrees... any ideas?

Sounds like the regulator is not controlling the flow of gas. Try this. 1. Turn gas tank and burner control knobs off. 2. Turn tank valve on VERY slow. 3. Open front burner knob on and lite grill. Wait a minute and turn on addition burners, (if needed).

Sear knob will not stay on (very loose fit). Other knobs seem tighter fit. The grill is brand new -- thus disappointed by post assembly quality control.

Pull the knob of of the sear burner valve shaft and check to see if it is melted on the inside, if it is, it will fit loose and needs to be replaced.

Weber grill will not heat up, reaches 200F and no higher

Also, it has to shut down the same way every time you use your grill.

Here is a Tip to fix a grill that not getting hot:
1. Turn the gas valve knob off. then close LP tank valve knob.
2. Unscrew the plastic hose coupling knob from the LP tank. You may hear a slight "hissing" sound as pressure is released this is normal.
3.Wait a minute then screw the coupling knob back on to LP Tank.
4.With lid open.slowly open LP tank valve.
5.Relight the grill the proper way by turning gas valve knob to ON position while turning the igniter knob at the same time.
6.After you are sure the grill is lit preheat the grill for 30 minutes.

This was called purging the line or releasing the air out of the line.

Another thing your orifice could be clogged with spiders or dirt. If it is LP gas check to make sure your hose is not kinked.

Weber won't get very hot

Safety valve needs reset.
  • Close the LP tank valve
  • Turn all burner control knobs to the OFF position
  • Open the grill lid
  • Turn the LP tank valve until it is completely open
  • Wait several seconds
  • Turn the front burner to the HI/Start position
  • Press the igniter until the burner is lit.
  • Turn remaining burners to High
  • Close the lid.
  • The grill should preheat to 500-550 degrees in 10-15 minutes
I called Weber and the rep walked me through the reset. All grills made after 1996 have this bypass valve.

Top knob no longer turns

The valve behind knob has probably gone bad and needs replaced(bad bushing from factory maybe). Check to see if your still under manufacturers 1 year warranty. Or order a new one off manf. website or ebay with model #. Good Luck, hope this helps.

The temp/flame on my weber grill won't get hotter


Check the excess flow safety device, which is part if the barbeque to cylinder connection, may have activated. To reset the excess flow safety device turn all burner control knobs and the cylinder valve off.
Disconnect the regulator from the cylinder. Turn burner control knobs to high. Wait at least 1 minute . Turn burner control knobs OFF. Reconnect the regulator to the cylinder. turn cylinder valve slowly.
