Put on new tank and grill won't ignite. Connection is tight. Once I heard the gas and now nothing. It's been days. I tried cleaning out a bit. The large black plastic cap does have some cracks in it when you look inside (where you attach the tank). Grill is 6 years old. New Ingitor kit?

Disclaimer- be careful when working with gas. Starters in gas grills are just about novelty anymore. Often, they only light 1/3rd or 1/4th of the burners and they usually stop working within one grilling season. I recommend using a wand lighter. Try to light just one burner but if doesn't light in 5 to 7 seconds, turn the gas off and wait to try again. Incidentally, you are turning the gas on at the tank, right? You should hear it when you turn the burner on.

Myra, the problem lies with the grill's gas regulator and how the tank was turned ON. Or the tank is empty.

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 that 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!!
Thanks for choosing FixYa.

What you have is delayed ignition. It's being caused by the gas regulator. It is solvable, though.

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

Wait 5 minutes and reconnect the hose to the tank.

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

Once the valve is fully open, light 1 burner and turn it to HIGH. Did the burner light and does th eflame height look correct? If so, light the remaining burner the identical same way. Now, to both flame heights look correct? If so, you solved the problem. Remember to always open the tank valve Very, Very Slowly. And always light the burners with the Lid/Hood Open.

If the above did not solve the problem, you will need to replace the Hose/Regulator Assembly. Since your grill is brand new, the Hose/Regulator Assembly will be covered under Warranty. Have your Proof of Purchase handy and call Weber 1-800-446-1071. Also, if you haven't done so already, register your grill before calling http://help.weber.com/register/ even if you don't need a new Hose/Regulator Assembly.

Hope this helped you troubleshoot & solve the problem.

You need an extra set of hands for the ignition assembly. The gas leak is probably in the tank connection assembly. The plastic fitting may be cracked. Unfortunately, you're the third person I have had in 5 days, that has had a leak in their Weber Q100. The last time I checked for someone, the gas tank fitting/holder was out of stock. No available date was listed. You may want to convert it to take a 20 Lb LPG Grill tank. Ironically, that conversion part is available.

Hope this helped you with the leaking situation and I wasn't kidding about an extra set of hands.

It sound s like the grill's regulator is locked up from "burping" the tank. Hopefully it's not a permanent lockup. To hopefully solve the problem, follow the steps below:

1. Turn the tank valve OFF and disconnect the hose from the tank.
2. Turn the burner(s) ON for 1 Minute, Then turn them OFF.
3. After 5 minutes reconnect the hose to the tank and open the valve VERY, VERY, SLOWLY (Slow
motion, slow).
4. Once the tank valve is fully open light one burner and turn it to HIGH. Did the burner light and
does the flame height look correct? Id so, light the remaining burner the way. Did it light and the
flame height look correct? If so, you solved the problem (with a little help).

If the above didn't solve the problem, the Hose/regulator Assembly needs to be replaced. What happened was this, when you turned the tank upside to "burp" the tank. The OPD Valve shot a hot load of gas to the regulator, when you opened it, as you normally would and permanently locked up the grill's regulator. That "burping" trick used to work with the old style tanks. Won't work with the new ones. You can get a new hose/regulator assembly at any home center or hardware store, that sells grills and accessories. They run about $30.00. Take your old one with you for comparison purposes. Once you install the new one and connect it to the tank. Open the Valve Very, Very Slowly, until it is fully open. Or you may have the same problem again.

Hope this helped to solve the problem. Happy Grilling!!

Do you mean it won't match light or the ignitor won't spark and light the burners? Or both?

If it won't match light or the ignitor sparks, but the burners don't light, that means you're not getting gas to the burners.

Check to the tank valve and make sure it's turned ON. Also, make sure that there's gas in the tank.
If both of those check out as OK, turn the gas tank valve OFF. Disconnect the hose from the tank and wait 5 minutes. Reconnect the hose to the tank and turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, light the burner farthest from the tank first and turn it to HIGH. Did the burner light and the flame height looks correct? If so, light the remaining burners following the same procedure. Now, are they all lit and the flames heights look correct? If so, you solve the problem. Just remember to always open the tank valve very, very slowly.

if the burners failed to light. Remove and clean all the burners, as well as the venturi valve on the open of each burner. Spiders like to build nest in the venturi valves.

if cleaning the burners did not solve the problem, you will need to replace the grill's hose/regulator assembly. You can find it in any home center or hardware store that sells gas grills and accessories, for about $30.00. Take you old one with you for comparison purposes.

Hope this helped you troubleshoot and solve the problem. Please be kind enough to let me know. Thanks and Happy grilling!!

Victor, are you sure you're getting gas to the burners after installing the new tank? You can try match lighting them to make sure. But, I suspect, that it's the installation of the new tank, that's causing the problem.

To test my theory, tune the tank valve OFF and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Ope the tank valve VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open, try lighting the burner that's farthest from the tank first and turn it to high. Did the burner light and does the flame height look correct? If so, light the remaining 3 main burners the same way. Did those burners light and the flame heights looks correct? If, so you solved the problem. Remember to always turn the tank valve ON VERY, VERY SLOWLY.

Hope this helped you solve the problem. Happy Grilling.

You got part of the solution correct. The 5 minute part, but you skipped a couple of steps.

Turn the gas tank valve OFF. Disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Open the tank valve VERY, VERY, Slowly (Slow motion, slow). Once the valve is fully open, turn the burner ON and push the ignitor button. When the burner lights, turn it to it's highest setting. If you have 2-burners, light the second the same way you did the first one. Do all the flame heights look correct? If so, you solved the problem.

If the above didn't solve the problem. you will need to replace the grill's hose/regulator assembly. As the OPD Valve in the gas tank, permanently locked up the regulator. Since your is a brand new grill with warranty that's enforce, contact the manufacturer for a replacement. Have you proof of Purchase handy, when you call them.

Hope this helped you solve the problem. Happy Grilling!!

If it won't ignite, because gas is not getting to the burners. Turn the gas tank OFF and remove it from it's holder. Wait 5 minutes and reinstall the tank. Turn the tank valve ON VERY, VERY SLOWLY (Slow Motion, slow). Once the valve is fully open, try lighting the burner(s) again and turn them to their highest setting. If the burner(s) light and the flame height looks normal, you solved the problem..

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

Do a few things, check that there are no gas leaks (soapy water) can help. if there are no bubbles, at the valve where you attached to the tank. shut the tank off wait 1or 2 minutes then slowly open the LP gas cylinder. try to start the grill. If nothing shut the gas off and check the flame grids for water,spider webs, or holes clogged with fat and filth. Also check the igniter for spark, dead batteries or bad connection at electrode may cause it to fail.
