The venturi is a narrow section, usually at the front of the burner, where the flow of fuel is temporarily constricted before being expulsed into the burner tube and turned into the flame. The most common blockage is within the venturi.
Thankfully because of these factors, they always disassemble easily. This is in part to increase the longevity of the sturdy enclosure surrounding the innards, but also because all that heat and the drippings from the food you cook do eventually take a toll on the parts inside (even with sturdy stainless steel). Now, the inside of your barbecue can be a daunting thing (especially if you don’t regularly clean it), but luckily, barbecues are designed to have their parts easily replaced. there is a popping sound coming from the barbecue.the flame colour changes suddenly and dramatically.one side of the grill is hotter than the other.A few things could indicate there's an issue with your burners: If you've deduced that the issue isn't arising from the gas supply line, then the issue is probably coming from within the barbecue itself. Therefore, if your barbecue still isn't getting up to temperature, move on to diagnosing the issue within the barbecue itself. Unlike liquid propane equipped barbecues, there is nothing similar to the OPD valve system that restricts the flow of fuel at the source if there is an irregularity detected. Screw it back together and leak check the connection again, if there are no more bubbles, hooray! This is the one time in your life you should be happy not to see bubbles. If you’re using sealant, apply just enough to cover the threads, there is no need to lather it on excessively. Remove the old tape or sealant from the connection, and attach a new amount keep tension on the tape while you apply it so that it molds to the threads of the connection uniformly. All that you need to do this is a couple wrenches to unscrew (and screw-back) the connection, gas fitters tape or pipe sealant, and your leak detector to check it again once you’ve pieced it back together. If you see bubbles form where you have put the leak detector, that means you’ve got a gas leak and it also means you should reaffirm that natural gas connection.
Webber gas grill gets too hot full#
If this has corrected your issue and your barbecue is once again grilling at full capacity, you’re free to go, but if not, the issue is at least isolated to being within the barbecue itself.
This is a funny issue because it can never happen to a tank and then happen suddenly, and also because few people even know about it at all. You should have full flow into the grill now, instead of the decreased flow triggered by the OPD valve. Here comes the tricky part: turn the knob on the propane tank very slowly, and once you’ve turned it all the way, it never hurts to turn it back a touch as well. The solution for this is easy all you have to do is turn the knob on the propane tank off, unscrew the propane regulator from the tank and then reattach it (this is more for posterity than anything). This is one cause the barbecue is not getting hot enough, because it won’t cut off the flow of fuel completely. This action of turning the knob on the propane tank too quickly is enough to set off some OPD valves and restrict the flow of liquid gas coming out of the tank. Sometimes, whether you’re overzealous to get grilling or running outside in the winter to preheat the barbecue (or as said unaware of the OPD valve in the first place) you may twist the knob too fast. It is essentially a safety valve, and while it’s something that we don’t usually notice (because it works), it sometimes works too well and this is when it becomes, not an issue per se, but certainly a nuisance, especially if you’re unaware of it. What the OPD valve does is restrict the flow of propane out of the tank if it detects too much at once, and also stops the tank from being overfilled. The most common cause of a reduction in heat to the barbecue is peculiar to liquid propane grills, for some time now (though you may remember a time before) it has been required that all propane tanks 40 lbs and under have an overfill protection device (OPD) fitted to them.
