Question about Weber Q Grill

2 Answers

Weber Q flame burns very low or not at all

My Q also 'burned dry'. Have filled up the tank, connected and reconnected the hose,done all the tricks about slooowwly turning on the tank, etc. I got it to light once but flames were very low and it burned out. Now I can barely get it to hiss and it won't stay lit. How can I tell if it is the regulator, clogged burner tube or neither?

    Thanks. I should have memtioned that I DO have the propane people check/reset that each time just in case.

    I have now been able to get the burner to light tho it is still not smooth and even. I had to let the tank sit open for a bit, then close, then reconnect, then open the grill valve, then open the tank slowly again and I was able to coax enough gas to get it lit. I had to go around the tube with a lighter and 'encourage' the various spots to lite up.

    Are there other safeties in the system (hose, regulator, other) that can be affected by pressure or that cold rush of expanding gas? Also, how do you clean the tube other than blow out? It sure looks like some of the holes are more open than others.

    Thanks and I hope this helps others...

    Do you have a five gallon propane tank? If you do, and you once turned it on too fast, it actuated the safety valve located inside the exit nozzle. Go to a propane dealer and ask him to reset the safety. Most dealers have a device that punches the safety back in place. Until it is reset, opening the valve "slowly" won't work.

I’d try cleaning the burner tubes. Use your brush front to back, not side to side, as this only transfers the grease from one slit to the other. If it’s been a while since you cleaned them, you might try Weber customer service. They sent me a new tube set, free of charge - this was several years ago. I’ve since given that Q away, moved to Florida and bought another Q. Love it.

SOURCE: low flame

Adjust the screw hidden under a sticker on the adjustment knob. That will increase the flow.

SOURCE: low flame on burner...

Remove the burner and check the flexible tubes for kinks or blockages. The flexible tubes usually just slip over the backs of the valves. Spiders love to get in there and block them. Also check that the holes in the burners are not clogged. Be careful when reseating the flexible tubes to be sure that they are properly seated on the back of the valves. Failure to properly seat the flexible tubes can cause leakage there, and the gas can ignite at the back of the valves and not reach the burner. Be certain that the replacement burner is designed to use with your grill and the flexible tubes mate properly with the back of the valves.

SOURCE: just bough weber Q200 grill. Is it normal that the

I have used the Q-series for 2 years. The blue and low flame is absolutely normal. Weber's philiosophy is of avoiding flare ups when grilling for best taste. I love this grill - very easy to clean, uses less gas and makes great food.

SOURCE: cannot get good flame on the burner of my baby weber grill. I've tried cleaning it checked hose, tank, regulator, seems to have good flow, but low flame only, even when set in high????????

I had this problem with a brand new grill so it wasn't grease in the hose. Due to the new propane regulators you have to turn the propane tank on for at least a minute before turning the grill to light. Let the tank sit in the light position for five seconds and then you light the grill. This will keep air from getting into the intake hose and will keep your gas flame roaring high.

I was only able to get the grill up to 250 degrees before I found this fix posted on the Weber site. It is listed as the number one solution in the FAQ section.

When gas is lit on grill flame is very small and then burns out

To solve this problem, first be sure you have adequate gas in the tank. If that checks out OK, do the following:

1. Turn the gas tank valve OFF and disconnect the hose from the tank.

2. Wait 5 minutes and reconnect the hose to the tank.

3. Open the tank valve VERY, VERY SLOWLY (Slow motion, slow).

4. Once the tank valve is fully open, light the burner farthest from the tank first and set the burner
control knob on HIGH. Does the flame height look correct for being set on HIGH? If so, light
the remaining burners the same way. Do all the burner flames 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 will need to replace the grill's Hose/Regulator Assembly. It runs about $30.00 at any home center or hardware store that sells grills & accessories. If you replace it, turn the tank valve ON Very, Very Slowly.

Hope this helped you to troubleshoot and solve the problem. Happy Grilling.

Low flame at burner. I've put a new tank on my grill and now the flame stays very low on all burners. I've heard that there can be some pressure problems with a newly filled tank. Is there a quick...

Mike, there can be some pressure problems, but it's not the new tank. However, it does cause the problem and here's how you resolve it.

1. Turn the gas tank valve OFF.
2. Disconnect the hose from the tank and wait 5 minutes.
3. Reconnect the hose to the tank and turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow).
4. Once the valve is fully open, light the burner farthest from the tank first and turn the burn to HIGH.
Does the burner light and the flame height look correct? If so, light the remaining burners the same
way. Now, do all the burner flames look as the should? If co, you solved the problem. Always
remember to turn the tank valve ON very, very slowly>

If the above did not solve the problem, you will need to replace the grill's Hose/Regulator Assembly. You can pick one up at any home center or hardware store that sells gas grills and accessories. It will run you about $30.00 (+/-) .

Hope this helped you to solve the problem Please let me know & Happy Grilling!!

Hi.. have a 300 series weber we bought only last year.. I cannot get the burners to come on together.. I can manually light the inner one but as soon as I try and manually light the outer one... it will...

More than likely, the grill's regulator is malfunctioning. To solve this, turn the LP Gas Tank Valve OFF and disconnect the hose. Turn the grill burners ON, wait 2 minutes and turn them OFF. Reconnect the hose to tank and open the tank valve VERY, VERY SLOWLY (Slow motion, slow) Once the valve is open all the way, light the inner burner first and turn it to the highest setting. Does the flame height look correct? If so, light the outer burner and turn to HIGH. Do both flame heights now look correct? If so, you solved the problem.

If you are using an insert-able gas canister, instead of a 20Lb LPG Gas tank, do the same thing as above, except remove the canister. Since there will be no hose/regulator assembly involved.

To provide further assistance, in case you have misplaced your Owners Manual, I have included a link to it that you can download and print for future reference, if you like.

Hope this helped you to solve the problem. Please let me know and Happy Grilling!!

Very low flame, can not see it burning bu feel heat

The Gas line Regulator to the tank is probably locked up. Turn the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the tank valve ON VERY, VERY SLOWLY (slow motion, slow). Once the tank vale is fully open try lighting the burner and turn it to the highest setting. Do the flames look as they should? If so, you solve the problem. If not, are you sure you have enough gas in the tank to sustain the burners on high? If the gas level is Ok, then you will need to replace the Hose/Regulator Assembly, as the regulator has gone bad. You can purchase one at any home center or hardware store that sells gas grills. Take your old one with you for comparison purposes.

Hope this helped you solve the problem.

With all three burners on high, the grill only goes to about 300 degrees F. All the burners are burning.

Has it ever burned hotter? I assume this is propane? If so the new safety valves I find are very finicky. Try turning off the gas. disconect hose from tank. Reconnect, turn back on gas and see if it is better. I

I had one that would not give full flame and sometimes I had to do this 3 or 4 times before it would give a full flame.
Good luck

Burner flames don't get hot, like not enough gas.

Try this, Turn off the tank. Disconnect it. Reconnect it. Turn tank valve back on very slowly and then see if you get bigger flame size.

Only enough gas flow for 1 of 3 burners

Shut off the tank and remove it from the grill. open all valves. close all valves. Reconnect tank to cooker and SLOWLY open the valve a hair. Then retry.Something in the dang newer safety tanks cause this phenom.

My weber Baby Q grill has a low flame.

Agree with rjmbridge. I called the Weber support people and was told that there is a built in safety feature on the regulator that will cause the flame to burn at a low setting if the gas within the extension tube to the large tank and regulator is not allowed enough time to equalize. They suggested turning on the gas from the tank very slowly, allow about 2 minutes with the temperature control knob turned off, then turn the temp knob on and light. This worked for me.
