There might be some reasons but one of the reasons that can cause fire risk is leakage. The leakage might be in the hose, in your tank, or your regulator.


How to check the leakage of the gas in the propane grill? It is simple and easy only if you follow these steps. 

  • Prepare a solution of soap and water or degreaser. 
  • Just rinse every part of your grill, through which the gas flows, with the soapy water.
  • Check for the bubbles. If the bubbles form on the hose then there is leakage in the hose or if the regulator shows bubbles then its time to change it but if the tank shows bubbles then it is tank leakage.
  • In such conditions, immediately turn off the gas supply to your grill and turn off every regulator or gas switch, and don’t ignite your grill. 

If the tank is leaking then you should change the tank and avoid using the leaked tank again as it may cause a fire. 


The flames of your grills become low when there is something in your hose, burner, or regulator due to which the fuel is not properly burning.

Check for the clogging in the hose first. If the hose is clogged, it won’t let the gas pas to the burners and hence your grill won’t even light up.

But if there is no clogging in the hose check the burners. Sometimes, the burner gets blocked due to the drippings of food which don’t allow the gas to flow and the burners won’t light up properly. 

Another reason for the low flames is that your propane tank may not have enough gas left to burn your burners at full heat settings. Check out for the gas through fuel gauge or measure the weight of your tank. 

How To Fix The Issue Of Low Flames - Grills Guide

There are several tricks that you can use and solve these issues. But remember every issue has its solving method and you cannot use one method to solve every issue. 

Hose Clogging

If your hose has been jammed and doesn’t allow the gas to pass through it, you just need to clean it. Cleaning the hose is an easier process. Just wash it thoroughly with soapy water or degreaser and a brush so that the blockage in the pipe is cleaned. Clean it thoroughly and remove every factor that can cause blockage. Check out best propane grills within the affordable budget.

Burner Cleaning

Cleaning burners is a detailed process as burners are quite sensitive and they may get damaged if cleaned harshly. Just use a brush that doesn’t have smooth bristles, a degreaser, and hot water. Wash it thoroughly with water and degreaser and use a stiff brush. Using a brush with smooth bristles won’t clean it properly. When you have cleaned it properly, adjust it in its place and start cooking on high heat. 

Bypass Grill

If you’re not getting enough heat then it is possible that your grill is in bypass mode for safety reasons. You can reset this bypass mode using these simple steps but make sure to follow every step exactly as mentioned. 

  • First of all, open the lid and set all the control knobs on the off position while the lid is still open. 
  • Now, turn on the gas supply to your cooking appliance by opening the valve of the tank while the regulators of the grill are still at off position. 
  • Wait for 1-2 minutes until the gas from the tank builds pressure inside the hose. This pressure will clear out your burners and will reset your grill. 
  • But the process isn’t over here, ignite your grill and wait for preheating. This preheating will take almost 10-15 minutes and your grill will reach a temperature of 400-500℉.

Further Reasons

Some of the issues are created by negligence in either proper burning or proper use of the grill. So make sure you don’t do any of these mistakes that will restrict your grill from achieving higher temperatures. When the grill doesn’t achieve high temperatures it is because of the reasons when you do and don’t do these things. 

  • It happens when you have set your grill at low-temperature settings.
  • When there is low fuel in your tank.
  • Sometimes your grill is heating perfectly but the thermometer isn’t working properly and shows a low temperature. 
  • When the hose or regulator is not properly attached. 
  • When the weather is too cold and is disturbing the heat.

These were some simple things that anyone can do unknowingly which will ultimately result in lower temperatures.
