Question about Weber Genesis Silver B Grill

1 Answer

Weak Gas pressure

As stated, my grill has developed a low pressure problem. Changed to a new tank, but problem persists. Suspect the regulator. Replaced it some time ago. Could be the burners, but doublt they would all diminish gas pressure simultaneously. Suggestions welcome.

My first thouht would be the regulator, but, as you indicated, this has been replaced. Check the venturi and make sure it's adjusted for optimum performance. The problem may be with the burners. Try removing them and cleaning them thouroughly.

I have a Vermont Casting VM450SSP Grill that needs a new Hose Regulator-S/B Valve Assembly. I have ordered two separate times what "Appliance Factory Parts" thinks is the part I need and both...


This ma=y be a case of changes in parts for your VC Grill. The ownership of Vermont Castings changed 6 years ago, when Majestic Fireplace, who was then the owner went bankrupt and Monesson Hearth products bought VC in the bankruptcy. Shortly there after, Monesson made some sweeping changes to the grill line (your model was discontinued) and really up graded what Majestic Fireplace had done with that line of grills. Overall, they started building a better quality grill.

Unless you have a piped in high pressure propane gas system, the one that Appliance Factory Parts furnished you should work fine (based on what I saw on their website). In addition, if you purchased your grill, prior to the change in 20lb LP Gas Grill Tanks Valves, 6 years ago. Some manufacturers changed their grill hoses to conform with the new OPD Valve grill tanks. It wasn't required, they just did it, to avoid regulators locking up, when the tank valve is opened to fast.

Hope this helped answer and solve the problem for you. Happy Grilling!!

Propane, LP, or Natural Gas Regulator Problems


There are many questions involving problems with gas regulators. Most any gas fired appliances will have a regulator somewhere in the system to regulate the gas pressure to the appliance. On natural gas the pressure regulator is often outside, but many stoves and ranges still have a pressure regulator at the inlet also.

On LP or Propane appliances there is a pressure regulator at the source but then also at the appliance. On outdoor grills the regulator is the silver round thing at the tank.
They often look like this.

The function of the pressure regulator is to keep the gas pressure even so that the flame does not vary much when the usage is increased or decreased. The regulator does this by using a small spring and diaphragm assembly. The counteracting pressures work to keep the pressure even. The regulator fails when it gets stuck. They are designed intentionally to fail in the safest mode or in a low pressure state rather then a high pressure. Therefore many problems involve not enough gas rather then too much.

On outdoor gas grills the regulator can sometimes get stuck if the tank valve is opened too rapidly. Or it will just become stiff from the outdoor environment. If the regulator is not letting enough gas through, try shutting the valve and then opening it again slowly. This will help sometimes. If that does not help and the valve is sticking, do not try to adjust the regulator. Replace it with a new one. Trying to adjust it could cause serious safety hazards. I have seen some web sites telling people to adjust the regulator by watching the flame…this can be a good way to get yourself and others hurt.

If you have a range, stove, or oven that is not working right because the flame varies as you turn burners on and off or when the oven goes on, then the regulator is at fault. Once again, do not try to adjust this to make it work, replace it and get it adjusted with the proper instruments to make sure that the gas pressure is right for the appliance.

Pressure regulators come in many shapes and sizes. They can look like any one of these here.

6c12f72.jpg
Gas appliances work at extremely low gas pressure. Natural gas appliances often run at 4” Water Column. Lp or Propane at around 10” WC. That means that the pressure of the gas will only raise the water in a tube 4” or 10 “. That is NOT much pressure and you can get that much by gently blowing in a tube.

So, if you are having trouble with not getting enough heat or the flame running very low, the pressure regulator should be one of the first places that you look.

Grill does not get hot. I have a fresh bottle of propane. Hose is not kinked. Grill is maybe 6 - 10 years old.


hi,
When a new or newly filled propane tank is attached to your gas grill, the OPD is usually at its maximum limit position above a tank filled to capacity. Propane may come through the valve too strongly due to the additional pressure of being full and the OPD displacement. The propane tank goes into check and limits gas flow when too much pressure hits the valve. Some grill manufacturers provide instructions for this in the users manuals but most people do not read the manual. Many grillers believe replacement parts are needed and burners, ignitors and regulators get replaced without reason. Depending on how efficient the grill is operating, some grills attached to a tank in check will not ignite and others will light but cannot reach cooking temperatures because the tank has limited the amount of propane released. Sometimes the food will be unable to exceed 200 degrees in temperature because the propane tank is in check.


Gas grill replacement parts are available and are sometimes necessary, low or no gas flow indicates a different typr of repair. Most grillers accept instructions and the problem is corrected in minutes -- but believe it or not I have had a few insist on purchasing replacement parts.
How do I fix grill?
To reset the check valve and get back to cooking on your gas barbecue grill, first
turn everything off. Turn off the grill, the rotisserie, the side burner and the LP gas cylinder tank. Once everything is turned off disconnect the propane tank from the gas grill regulator by unscrewing it or pulling the quick-release on older or retro-fitted propane cylinders. Now turn the grill on. I know, it is dis-connected from the gas tank but we want to ensure that the pressure in the gas lines or any gas in the burners is released. Leave all grill burners in the on position for 3 - 5 minutes before turning them off. Make sure. Most gas grill valves must be pushed in to turn them and if turning is attempted without pushing the knob, they will not turn to the "on" position. With the grill, et al turned off reconnect the propane tank and slowly turn the hand wheel to the open position.
Slowly. The trick here is to turn the hand wheel slowly. Propane in a new or very full tank will be under more pressure, especially with the OPD floating in position. The extra pressure will come through the tank valve stronger. Turn the gas tank slowly allowing small increments of propane to enter the grill.


Once this is complete, you should be able to turn the grill on high and ignite your gas grill burner. Your cooking heat should be back to normal and cooking times decreased. If the problem persists, try this process again to make sure you followed every step. The check valve exists to save your life if there is a leak in any of the gas fittings. Constant check valve issues could imply a gas leak and a visit from your local gas grill service technician may be necessary.
To find a leak, turn the grill valves to the off position and the gas tank valve to the full on position. This should pressurize the gas line. Spray soapy water on all the fittings and look for bubbles just like checking for the leak in a flat tire.
Do not attempt to correct a gas leak on your own. While a check valve error when your gas grill will not get hot or will not ignite is a user education error and an issue corrected by learning about your propane tank, a gas leak should be corrected by a licensed gas service technician. When you are grilling, turn the propane tank on first and then turn on your grill. When you are done cooking, turn the gas tank off first and then turn off the grill valves. The process releases the pressure in the gas grill hose and manifold which allows the gas tank to release pressure by filling these lines. Read the safety features of your gas grill, clean it when necessary and replace used and failing parts. Aside from that be safe, eat well and have fun.

thanks.

Low flame


Next time you use the grill turn the gas on slowly. For some unknown reason when turned on quickly the regulator reduces the gas flow.
Another problem with some gas fittings is an auto shutoff if detects the slightest leak. Sometimes the shutoff is not 100% and allows a small amount of gas causing the weak flame.

Genesis s310 stainless grill. Does not fully light.


Regulator is not bad, as I stated before new valves are designed to reduce gas flow if valve is opened to fast. This is so if grill catches on fire, the tank will shut itself off, thus propane will stop flowing causing fire to extinguish itself.

Very low flame, like very little gas is getting thru, tank is ful


Okay, what you are dealing with is called "vapor-lock". The way these grills need to be turned off is, close the tank valve first and after the burners go out, then turn the burners off. The way you are doing it is trapping the gas and you are getting a weak flame. Fortunately this is an easy fix. First, light the grill by turning the gas valve open, then turn the burners on to light the grill...as soon as that is done, close the gas valve on the tank then turn the burners off. Repeat this procedure until you get a good flame. If this procedure hasn't fixed the problem after the third time, you need a new regulator and regulators are easy to find in any home improvement store like Lowe's or Home Depot.

Weber Silver Genesis C regulator purging gas after reset process


This could be caused by a couple of problems. First the regulator could be bad, or the tank is getting to hot. Which causes the relief valve to open and release pressure. This will happen when weather outside is hot.

Grill with a full tank of gas will not get hot


Low flame, low temperature, yellow flame: This has become the biggest problem with many grills these days and it's almost always because of the regulator (the funny UFO shaped thing on the gas hose). Regulators seem to be stickier these days and when they stick you don't get enough gas to generate a good grilling temperature. To get your regulator unstuck you need to release the pressure on it. Follow these steps exactly:
  1. Turn off the gas at the propane tank
  2. Disconnect the gas line from the tank
  3. Open the grill lid
  4. Turn all control valves to high
  5. Wait for about a minute
  6. Turn all control valves to off
  7. Reconnect the gas line to the tank
  8. SLOWLY turn on the gas at the tank
  9. Light the grill normally
  10. Your grill should now heat normally
To keep the regulator from sticking again make sure that you turn off the control valves first, then turn off the tank valve. Always open your tank valve slowly. If this doesn't work give it a second try. If you still have low flame then you probably have a faulty regulator that will need to be replaced.
