Question about Brinkmann Charmglow 810-7400-S Propane Grill
It could be a defective LP gas regulator or a restriction somewhere in the gas line for the bbq. This can also happen if the propane tank is overfilled.
First make sure that the LP tank is not overfilled. If you open the bleeder hole on the tank(small screw next to the valve) there should be no liquids coming out. If liquid propane is coming out then the tank is overfilled. Keep the bleeder screw loose until the liquid disappears then tighten. Re-connect the tank and see if that fixes the problem.
Then inspect all the gas lines on the bbq. Make sure that there are no kinks or crushed lines.
Then take a look at the gas regulator. Try turning on all the burners then give the regulator a couple good taps on the housing with something solid. See if the burner changes size. If it does and then goes back down it could be the gas regulator. Also take a look at the regulator housing. There should be a very small hole on the housing and it might be labled "vent". Make sure that this little hole is not plugged with any debris or that can cause a low pressure problem. You can use a sewing needle to gently poke out the hole. You will know if it worked because the burners will become much higher. And you could also try disconnecting the hose and regulator assembly from the bbq then turn on the LP tank slowly with the regulator connected. You should get plenty of gas flow from the end of the hose. Then use your hand to block and release the flow a couple times to try and clear any debris that might stuck in the regulator.BE VERY CAREFUL DOING THIS!!! MAKE SURE YOU ARE CLEAR OF ANY SOURCES OF IGNITION BEFORE TRYING TO CLEAR THE REGULATOR. Then reconnect the hose regulator and tank to see if the problem is fixed. If you are getting very low flow from the hose with the regulator disconnected then it is probably a defective regulator. They are pretty standard and you can purchase a new LP hose and regulator assembly from most home improvement stores.
If the regulator checks out good then I would think that there is a restriction in the main gas line for the bbq after the regulator. You will need you dis-assemble the main line and blow it out with some compressed air to clear the restriction.
