Try turning off the tank, disconnecting it, then reconnecting it. Then very slowly turn the gas tank back on. Also make sure your tank isn't almost empty! The empty weight of your tank is stamped on the collar as T.W. (tare weight). 1 gal of propane weighs 4.25 lbs. Put it on a bathroom scale and see if it weighs less than the tare weight + 4.25 lbs. Let me know if that solves it. If not, we'll dig deeper. Douglas

I have a Cook by Number gas grill, model LG36C, that isn't cooking as hot as it should. I've disassembled all the gas lines and blew them out with compressed air. I cleaned the burner. I cleaned the...

Since your grill only has one main burner and it requires more gas to heat with than the side burner. I still suspect you have a grill regulator issue. But, if you've done your research, you know it's easy to solve. Turn the propane tank valve OFF. Disconnect the hose from the tank valve and wait at least 5 minutes before reconnecting it. Once it has been reconnected, turn the tank valve on VERY, VERY SLOWLY (slow motion, slow). Once the tank valve is fully open, turn your main burner on, light it and turn it to high. Do the flames appear to be higher than before? If so, light and turn ON the Side Burner. Now do all the burner flames appear to be higher than before? If so, you solved the problem. If not, either the grillhose/regulator assembly needs to be replaced or the Venturi Valve on the main burner needs some adjusting. As the air to gas ratio may be off sightly.

Hope this helps to solve your problem and Happy Grilling!

Only used the grill once and had no problem starting it. The second time we tried to use it , it wouldn't light. Tried a new canister, still wouldn't light. What could the problem be?

Are you able to tell if there's any spark coming from the igniter? If not, you may try cleaning it. If it doesn't spark and/or click; your igniter may be faulty.
Next try turning it on and lighting with a match; use a long one. :-)
If it lights in this manner; that should tell you there is something wrong with the igniter.
Could be out of alignment, loose, broken, etc....
If it still isn't lighting; the problem is likely a gas flow issue.
Make sure the burners are clean and dry. If you stored it a while after that initial use; you may even have had some critters get into the gas tube/burner. Make sure that's all clear. Try to light with a match. If it's still not working. It's likely either the gas valve(flame adjustment knob) or the regulator. More likely it's the latter.
With it being so lightly used, I'm not sure why the regulator would go out, but it happens.
One thing I'm not sure of, but your regulator may have some sort of safety mechanism that is shutting the gas flow off, you may want to look into that. If you've got the manual and/or instructions still, it may very well indicate any safeties to look into before replacing the regulator.

Good luck!

Oven not heating properly

Hello- Sometimes ignitors work enough to light burner, but not enough to step up gas flow at regulator. Lower burner ignitor is bad if resistance is less than 4ohms. New part through local app. parts store.- 50-75$. Ignitor is mounted next to burner under bottom pan in oven. Plug is behind pan drawer. Fairly easy to replace. hope this helps- Thanks- ED

Orange flame comes out of left side burner

Try cleaning the orfice that feeds that tube sometimes you can get debris in the lines when changing tanks that can clog them or the valve itself.

Char Broil commercial grill won't heat pass 300 degrees

I had a similar problem and thought the propane kept running out....come to find out it was a defective regulator. $21 at the local ACE store as running to LOWES and trying to get a point across to a 17 yr old summer help college kid for a intermittent problem seemed more challenging then it was worth. Would barely light the burners and would not get over 200 degrees. Ripped it apart...blew through all the orfices including the regulator put it all back together and would work for a while then fail again. Good luck!

Kenmore 4 burner grill only lights 3 burners

Looks like your regulator is not venting properly to relieve the back pressure. The best thing you can do here is replace the regulator.
