The most common gas grill regulator issue is a weakening or ripped bypass valve often caused by normal wear and tear. It may also be faulty manufacturing but this is less likely to occur.
I grill a mean barbecue every weekend and have encountered my fair share of grill complications. Over the years, I have learned how to detect and fix most of these promptly.
While common wisdom may tell you to replace the grill regulator as soon as any hitches appear, some of these issues have simple quick fixes that you can handle.
In this article, I have talked about a number of these problems along with their solutions. I have also outlined how gas grill regulators work as well as some of the other hurdles you may encounter when grilling. Read on to find out more.
The most common issue associated with faulty gas grill regulators is low temperatures and weak flames. This is certainly not fun.
A low flame can’t reach optimal grilling temperatures. This causes uneven heating which means that you can’t cook your food effectively.
As mentioned earlier, the regulator could be in need of replacement if the bypass valve is ripped or worn out.
If the valve is still functional, there may be uneven back pressure on the gas regulator valve, preventing the gas supply from flowing normally into the regulator hose.
This can be fixed by pushing or forcing out the vapors from the gas regulator until the pressure evens out. Think of it as ‘burping’ the regulator.
If the gas grill is producing a flame that is orange or yellow instead of blue, it means there is a malfunction and that complete combustion of the vapors is not reached.
Complete combustion can only occur if the propane gas mixes with just the right amount of oxygen, at which point the flame will be just perfectly hot and blue.
These orange and yellow flames also produce less heat than the desired blue flame and this is not ideal.
Yellow and orange flames can be fixed by ensuring that the gas flow to the burners is not obstructed. The culprit could be the venturi tubes which may need to be adjusted to optimize the flow of gas in the burners.
Venturi tubes regulate with high precision the amount of air and gas mixture reaching the burner for ignition. When the tube is not well adjusted, either too much gas or too much air gets through for ignition.
If too much air goes through, you have very little gas in the mixture to make a stable flame. The excess air pushes the weak flames outward, haphazardly causing low and uneven heat.
If too much gas is getting through, then it combusts in its pure form producing yellow or orange fire which is lower in heat and will produce charring and soot.
If you fire up your grill and get no flame, you will end up with a bunch of hungry guests. This is nothing short of infuriating but before you order out, you might be able to fix this.
Assuming your tank is full, your gas may not be reaching the burners because there is a gas leak. The leakage could be on the gas line or hose, at the connection point to the grill, or at the regulator.
This is not a common occurrence but it does occur when the atmosphere outside the propane tank is very humid. Since the fluid inside gas tanks is very cold, its vapors may settle and condense inside the regulator, causing it to freeze and get stuck.
This problem usually resolves on its own but just to make sure it doesn’t persist, be on the lookout for these two things:
Firstly, ensure the propane tank is sitting on an even surface and is upright to avoid precipitation settling awkwardly in the regulator.
Secondly, in case your gas tank has been freshly refilled, it could be overfilled in a way that there’s no room for optimal movement of the gas vapor through to the regulator. So it quickly gets trapped and condensed in the regulator before it flows through the gas line.
This is difficult to determine but the fact that the regulator valve won’t budge is a reliable sign that there may be precipitation preventing the valve from functioning smoothly.
In an open area such as your backyard, use a different regulator to release some of the gas to stabilize the pressure of the gas tank.
If a different regulator doesn’t resolve the issue, then your regulator may be unfixable at which point you should consider a new regulator.
It goes without saying that tinkering with your gas grill regulator and other parts is not a job for just anyone.
If you have no understanding of how gas grills work, attempting to fix gas grill regulator problems may result in damage that you may not be able to determine immediately.
Always turn off the propane tank valve and disconnect the gas line before inspecting the parts to figure out where the hitch is.
If the grill had been on, turn off the controls and allow the grill to cool off completely before getting to work.
If the above methods yield no results, consult a professional. Your local hardware store should be a great resource.
Finally, replace the propane tank regulator if you want. They are inexpensive and easy to replace, plus a new regulator is certainly a better option than a repair-prone regulator.
Basically, your regulator is the gatekeeper for your gas tank. The propane regulator controls the gas supply to our gas grills.
It keeps a tight lid on the liquid fuel within the propane tanks when the grill is off and regulates how much of the evaporated vapors can flow to your grill burners for ignition.
It goes without saying that a defective regulator can’t be relied on to safely keep the highly flammable propane gas secured and safe.
When this is the case, you will have gas leaks as well as other gas grill regulator problems, making it an inefficient and dangerous piece of equipment.
Additionally, a faulty regulator will release the wrong amount of gas vapor, causing wastage as well as ineffective handling of the grill. I have found the GasSaf Propane Regulator and Shinestar Universal Gas Regulator to be dependable regulators with excellent durability.
There may be other hitches that indicate more gas grill regulator problems or malfunctions in other parts of the grill.
While it’s possible that the bypass valve or regulator is bad, if you observe any of these occurrences, it’s time to speak to a technician about some returning and repairs. They are:
When your grill produces too much smoke during cooking, it likely means the burners are choking with grease and when it burns it produces these annoying clouds. Deep cleaning of your outdoor gas grill should fix this issue.
If you don’t clean the burners and the grease continues to burn, the burners will acquire a hard layer of char, crust, and soot.
This will, in turn, decrease the efficiency of your grill and permanently damage the burner. Spring for a deep clean of your grill when you notice excessive smoke.
If your grill doesn’t ignite, the likely culprit is the ignition controls or faulty wiring. If all the burners have independent ignition and only one of them ignites, then the ignition controls could be faulty.
Carefully check the controls and control valves for build-up which could cause the knobs to fail. Use a stiff wire brush to rid the spring of any crusty build-up and return the knob. It should produce a clicking sound when pressed or rotated for ignition.
If this doesn’t work, you should have a professional repair or replace it altogether.
If the grill burners share their ignition but will not ignite, the wiring may be damaged. You won’t be able to fix this yourself.
The better option would be to let a technician fix it just to be on the safe side.
As mentioned above, leaping flames could mean that the venturi tubes need an adjustment to regulate how much air gets through the air shutters to the burners.
It may, however, mean that the burners are malfunctioning and gas pockets are forming periodically above the burners. They may catch fire before escaping into the air.
Check your burners for damage and wear, then replace the ones that are causing the flames to leap out haphazardly. In time, this kind of damage could cause accidents and injuries so get to fixing this issue.
If your regulator is functioning like a dream but you’re still getting uneven heat, the burner ports could be clogged with grease runoff. If you inspect your grill burners, you will notice a line of holes through which propane gas flows and ignites.
A perfect blue flame can only be achieved if the gas burner ports are clear. If you have clogged gas holes the flame burns inefficiently creating uneven heat, yellow and even orange flames.
This situation is easily fixed by using a stiff wire brush, some warm water, and oven cleaner. Simply scrub away at any of the crust, soot, and grease.

For the most part, regulators tend to be very reliable over incredibly long periods. That said, they do get damaged by normal wear and tear, rough handling, or accidents.
If yours is acting up, the solutions above should help but by all means, replace a pesky regulator instead of tinkering with equipment repeatedly.
Keep in mind that your grill has a bunch of other parts that could malfunction, including the burners, the propane gas hose, and the ignition system among others. Check these too and square any issues for the best grilling experience.
Good luck and happy grilling!
