Bruner will not heat past 140 degrees, just bought a new tank

Well, if turning OFF the tank valve, disconnecting the hose and wait 5 minutes before reconnecting it. And then, opening the tank valve VERY, VERY, SLOWLY (Slow motion slow) before lighting the burner farthest from the tank first and turning it to high didn't work. You need to replace the grill's hose/regulator assembly.

You can purchase one at any home center or hardware store that sells gas grills and accessories. They run around $30.00. Be sure to take your old one with you for comparison purposes.

Hope this helped you and Happy Grilling!!

Electric water heaters never power BOTH the upper and lower elements at the same time.

If the water in the tank is cold, either the top OR bottom element will be powered through the upper thermostat (t-stat), never both at the same time. The upper t-stat will send power to the upper element until the temperature of the water in the top of the tank reaches the set point of the t-stat say 140 degrees. When the water temperature in the top of the tank reaches 140 degrees, the t-stat is "satisfied" and disconnects the power from the top element and sends it to the lower t-stat.

IF the temperature of the water in the lower half of the tank is lower than the set point of the lower t-stat, the t-stat closes to send power to the lower element. The lower element REMAINS powered by the t-stat until EITHER the water in the lower part of the tank reaches the set point temperature of the lower t-stat again, say 140 degrees; OR the temperature of the water in the upper part of the tank drops, at which point the upper t-stat "calls" and switches the power away from the lower t-stat and sends it to the upper heating element instead. When the top t-stat is satisfied, it switches power back to the lower t-stat. The process will continue back and forth for as long as needed to bring the temperature of the water in both halves of the tank to 140 degrees.

You must wait until the top of the tank is heated - before the lower element will be powered to heat the water.

I hope this helps you understand how the switching happens in these water heaters. Good luck! Please rate my reply. Thank you.

The new style OPD valves have a small brass ring located in the female fitting on the LP tank. Over time this ring can work loose and then it does not allow the male fitting to fully depress the OPD valve thus reducing your gas flow
Using a small flat bladed screw driver tighten the small brass ring This should solve your problem
IF not you might want to remove the cap (white) on your regulator and try slowly adjusting the regulator, make small adjustments and try the BBQ My Weber if I set the front and back burners to MED I get right at 350 degrees in 60 degree outdoor temps. Adjusting the regulator will take some time to get it right but If it is not your tank it is most likely your regulator out of adjustment

either your regulator is not hooked up to the tank all the way try to turn tank off make sure all knobs are turned off disconnect tank then reconnect turn tank on and try again if this doesnt work the regulator is bad

It sounds like the regulator is shutting down and preventing the grill from getting all of the propane it needs. to remedy your problem disconnect the tank and then reconnect it. Usually that is all it takes to get the regulator to work properly. If the problem continues just get a new hose with regulator attached.

are the fire red , orange or blue?
must likely is the burner control.
check the air control at the back of the burner control, it should be open all the way.
it it is, then try another themostate.

Hi John,

I just experienced the same exact problem ! I just bought a brand new Weber E-310 a 3 burner grill.
After I seasoned it up with cooking oil,I turned all the burners to high, opened the tank and clicked electrnic button several times , the grill was on then I went inside, I came out about an half-hour later and it was saying around 275 degrees..
I looked into my manual and there is a gas limit control valve that shuts down gas flow, when it thinks there is too much gas flow.

Sloution;
Turn the propane gas knob to off
Turn the gas grill knobs to Off.
Click the igniter several times to clear out any gas.
Then unscrew the regulator from the tank,( I then blew into the tank hole and regulator),
Screw back on the regulator to the propane tank.
I then clicked igniter again couple of times.
Now open your propane tank.
Then turn on front burner while clicking igniter, this will lite 1st burner.
Then turn 2nd burner on low then to high.
And if you have 3rd burner or more, turn low then to high!

John I did this and my grill went to 600 plus in a few minutes!!

The problem was turning the gas grill knobs on first then opening the tank then lighting...
You have to open propane tank with knobs off, THEN AS SOON AS YOU TURN ON 1ST KNOB, YOU MUST IGNITE ...

Might be easy! diconnect hose from tank ..and re-connect... this has worked for me in the past

sudsy, this exact same thing would happen to me every time I changed a tank. I know it's nothing to do with the grill itself. I would have to seat and reseat the regulator hose to the tank a couple of times before it would start heating normally. Your model has 3 burners and I suspect that the flame is real low on each one even on the high setting. Try connecting and disconnecting the tank a couple of times and see if it comes to life. If worse comes to worse you can order a new regulator hose. Part number P3632L. Catriver..post back.
