Re: grill won't heat up above 200 DEGREES with a nearly...
I have a brand new weber grill genesis...It happened to me...I have a 3 burner...light the first burner on high....then turn down to medium...then light second burner on high...turn down to medium....then the 3rd burner on high...turn down to medium.....wait 5 seconds and bring them all to high. Apparently since they are larger burners it gives a chance for the gas pressure to equalize. I haven't had a problem since doing it that way. Don

Try turning off the valve to the tank, then leave the knobs on the grill open for 2-3 minutes. Turn off the grill knobs, slowly, slowly open the valve on the tank. Relight the grill and see if it gets hot.
Had the same issue with the three burner model, the grill wouldnt heat as quickly as it should. Thought it was an issue with the regulator but decided to work our way from the burners to the tank to eliminate possible causes. we got to the valves were you select the heatnig level and discovered that sugar ants had gotten into there somehow and died, enough of them to block the valve without completely closing it. to solve we removed the valves, disassembled them and ran a pipe cleaner through them to clean any buildup away. after doing this for ll three and reassembling the parts and putting them back onto the grill it works perfectly and heats up like it was brand new.
You may have to recheck the tank for full. If you forgot to turn off the tank after the last time you used the grill, the tank could have leaked down. I always keep a spare full tank for just those types of problems. If the tank is full, then the regulator may have a problem. That grill should be able to get over 300 degrees.
zonfish - if you're tuning the gas tank off at each use, as you should. The problem lies in your grill's gas regulator, but it also is not a big deal and is easily solved.
Whenever, you open the tank valve, do it VERY, VERY, SLOWLY (Slow Motion, slow), until it is fully open. Then light the burners.
What happens is this, LP Gas Grill Tanks are now equipped with an Overfill Protection Device ("OPD"). And often time, when you turn the valve on like you would normally do, the OPD Valve sends a hot load of gas to your grill's regulator and partially locks it up or locks up entirely. Therefore, the burners are not getting enough gas to heat the unit up to 500 degrees. Opening the valve very, very, slowly, overcomes this problem.
More than likely, it's the OPD valve on the LP G tank. When it won't heat up above 300 degrees is after the tank was turned OFF & then turned back ON? If that is the case, disconnect the gas line from the tank, wait 5 minutes, reconnect the hose to the tank and turn the tank valve On VERY, VERY SLOWLY. This will keep the tank valve from locking up the grill regulator and thereby, gas will get fully to each burner. If this doen't correct the problem the first time, repeat the above procedure.
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. I HAD THIS PROBLEM JUST LAST NIGHT AND FIXED IT RIGHT THEN.
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.
