Gas Grill Gets Too Hot On Low Setting [6 Easy Solutions]

A couple of reasons cause the gas grill to get too hot on low setting. Especially your gas grill gets too hot on low setting due to the high outdoor temperature, gas regulator issues, and dirty grill components. Besides installing the wrong type of orifice, getting a high-pressure burner, and a clogged burner can also cause a high heat issue. Below, we will break down each of the issues. So, stay in tune. 

Gas Grill Gets Too Hot On Low Setting [6 Easy Solutions]

Here are the common reasons explained why your natural gas grill gets too hot on a low setting and their simple solutions:

Note: You can also why the gas grill knob is hard to turn and how to fix it.

1. Outdoor Temperature Is Too Hot

If you operate your gas grill in the middle of the day or during the heat of Summer, you may find your grill running hotter. Higher temperatures outside may cause your grill to run a little hotter, even on low settings. 


This is not a grill problem at all. Just bring your gas grill under the shed. We recommend you to not operate your grill in the middle of the day during the summertime. We hope you don’t encounter this grill issue if you follow our suggestion. 

2. You May Install High-Pressure Burner

It’s important to consider whether you install a high-pressure burner or low which makes a big difference. A low-pressure burner will burn at lower temperatures. On the other hand, a high-pressure burner will burn at higher temperatures. This is the issue that may occur in your case. If you install a high-pressure burner, your gas grill will get too hot on low settings. 


The solution to this weber gas grill issue is pretty simple & straightforward. Just inspect whether you install the right gas burner or not. If not, replace the high-pressure gas burner with a new low-pressure burner. 

3. Gas Grill Regulator Problems

A gas regulator on a grill regulates the flow of gas from your gas tank to the heating mechanism of your gas grill. Generally, it’s a safety device, which adjusts the gas pressure. If it gets defective, you can’t control the gas flow. In other words, you will have no control over the heat your grill produces. 

For example, if you install the wrong type of gas regulator (especially a high-pressure one), it will flow more gas to your grill burners. As a result, you will get more heat or the grill will run hotter even on a low setting.  

Similarly, the incorrect installation of the gas regulator can also cause your grill to run hotter. 

In some cases, you may mistakenly install a propane regulator on your gas grill. In return, it will shoot up the flame and temperature of your gas grill at a low setting. Keep in mind, both propane regulators and gas regulators are not the same and they are not interchangeable. Indeed, a propane regulator will never control the gas flow to your gas grill optimally. 

Lastly, a damaged gas regulator can also be the caveat behind this grill issue. If you don’t maintain the regulator regularly, dirt & debris will nest on it and block the regulator. Due to the clogged gas regulator, you will get uncontrolled gas flow which will lead to dangerous situations. 


To solve this issue, ensure you install the right type of gas regulator on your grill. If the heat output of your grill is below 60000 BTUs, a basic gas regulator will be sufficient. However, it’s better to check & read the BTU rating of the regulator before purchasing one. 

On the other hand, you should get a single or two-stage regulator if the gas grill is over 60000 BTUs. 

Once you choose the right type of gas regulator, it’s time to install it professionally. If you have a natural gas grill, install the regulator in the gas line of your house and tie the gas grill downstream of the gas regulator. 

Next, make sure you pick a gas regulator for your gas grill. Never use a propane regulator for controlling the gas flow of your natural gas grill. 

And finally, inspect the gas regulator for a clog by dirt & debris. If it gets dirty, clean it thoroughly to release the blockage. Otherwise, you should replace the gas regulator if it gets damaged. 

4. Grill Components Get Dirty

Dirty grill components can also cause your gas grill to trigger high temperatures. If the grill grate, cook pan, and heat deflector get heavily coated with burned grease, you will experience flare-ups or grease fire. And the internal temperature of your gas grill will be too high if the grease fire occurs. 


After every cook, we recommend you clean the internal parts like cooking grates and drip pan. You can use a wet cloth to wipe away excess oil or grease from the cooking grates. If needed, remove the grill grates from the unit and clean them with soapy water. In short, you should keep your grill clean to avoid potential accidents like grease-fire. 

5. Mistakenly Install A Gas Orifice For Propane Grill

You can find an orifice installed on the burner control valve. It works like a nozzle to maximize the velocity of the gas to let the gas mix with air in the venturi tube for combustion. 

The orifice of a gas and propane grill is different. The natural gas orifice is double the size of a propane orifice. If you install the gas orifice for your propane grill, more gas will flow to the burner. Consequently, your propane grill will get too hot. 


Install the right size orifice on the burner control valve of your propane grill. To detect the proper size, take a 3/64” drill bit shank and try to insert it into the orifice. If you can’t insert it into the orifice, understand it’s a propane orifice. 

Don’t forget to inspect the orifice for carbon buildup. It can also cause your grill to run hotter even on a low setting. If there is carbon buildup on the orifice, clean it with a damp cloth. 

6. Burner Gets Clogged

If you don’t maintain your grill regularly, food particles or grease will build up and restrict the gas glow. Consequently, you can see inconsistent flame out of the grill burners. 

A huge flame will come out from some areas of the grill burner. On the other hand, there will be too small flames in some areas. This restricted gas flow to the burner will cause uneven heat distribution which creates several hot spots. If your thermometer is somehow placed above the huge flames, it will read and display the high temperature of your grill. 

Either way, your grill will distribute the flame unevenly if the holes of the burner are unmatched or they get clogged by debris & carbon buildup. 


Clean the internal parts like the grill grate and drip pan regularly so that grease can’t build up and clog the burner. If the burner gets clogged, release the blockage by cleaning it. 

Also, don’t forget to clean the small holes or slots of the burner. You can use a small screwdriver or a brush to clean those slots. You can check out this article from Weber to learn how to clean the burner tubes

What Temperature is Low, Medium, High Heat on a Grill?

If you are just getting your feet wet in the grilling world, you perhaps don’t know about the low, medium, and high settings on a gas grill. To cook multiple recipes with a grill, you must know about these heat settings. Below, we will break down all of these temperature settings. 

Low Heat

The low heat setting on a grill falls between 225F-250F. It is a perfect temperature range for imparting smokey flavor to the meat. When it comes to Weber, 250-350° F is the low heat on a Weber gas grill. 

Medium Heat

What is medium heat on a Weber gas grill? 350-450° F is the medium temperature range on the Weber Grill. However, the average medium heat in most grills is between 325-350F. You can cook a wide range of recipes including roasts, poultry, and so on. 

High Heat

The highest temperature of most grills can go up and down between 450-600F. At this high cooking temperature, you can cook fish, steak, chicken breasts, and pizza.  


After reading the article, now you know why your gas grill gets too hot on low setting and how to fix it by yourself. So, whenever you face such a heating issue with your gas grill, investigate the factors we explained and solve the reason.
