 1. Fix Regulator Problem

The primary reason for causing a low flame in a gas grill is the regulator stuck. Or sometimes defective regulator creates problems with the igniter functions. The only solution is to reset the regulator properly. Here are the possible ways to reset it.

  • At first, turn off all burners of your gas grill.
  • Then, you have to turn off the propane tank. In order to shut off it, just turn the valve clockwise.
  • After that, disconnect the regulator hose by unscrewing it.
  • Now, open your gas grill lid.
  • This time, turn the burner knobs into a high position.
  • Leave it for about 5-8 minutes.
  • Then, reconnect the regulator hose correctly.
  • Turn on the gas but slowly.
  • Your grill regulator is being reset. This time, light your grill in regular ways.
  • If still a low flame there, be sure the regulator has become faulty. You need to replace it.

 2. Check Propane Tank Leaking

Now move through the second most possible reason: propane leaking from the tank. To check if really the propane tank is leaking or not, go through the following steps:

  • Take a bowl and mix 1-tablespoon of detergent and some water into it. 
  • Now, check whether the valve of the propane tank is fully opened. 
  • Then, start applying the soapy solution water on the valve and along all the sides of the propane tank. Use a brush for better applying.
  • If bubbles appear, this is a sign of propane leaking. 
  • Turn off all burners. Quickly replace or repair the leakage items.
  • If there are no bubbles, check the following section to check OPD. 

 3. Reset Tripped OPD

Another common reason is that OPD or overfilling prevention device is activated. This is a safety device for your gas grill, which restricts the excessive gas flowing during gas leaking. Sometimes, turning burner knobs before turning on the valve also tripped the OPD. 

For activating OPD, the temperature of the grill automatically falls too low. Anyway, you can reset the OPD by following methods:

  • Start by shutting off the propane tank valve.
  • Now turn off all burners knobs.
  • Then, unscrew the hose and disconnect it from the propane tank.
  • After that, open the grill lid.
  • Leave it for 30 seconds.
  • After that while, reconnect the regulator to the back position.
  • Now slowly open the valve. Make sure you are not putting excessive pressure.
  • Turn on the burners and light the grill. 

 4. Clean Blocked Gas Orifice

After a long time using, there may be clog debris and spider webs in the gas orifice. For that, it will fail to ignite the burner properly. You should clean out the orifice periodically to keep the appliance effective. To clean the orifices, follow the below steps:

  • At first, turn off all burners knobs and let the unit be cool.
  • Then, remove the control knobs and orifice slowly.
  • Take an orifice cleaning tool and start cleaning.
  • It will be better to clean the blockage of the orifices using a long wire.
  • After cleaning, assemble the gas orifices correctly. 
  • If there is still a low flame in the grill, contact the nexgrill customer service

 5. Check Fuel Level

Insufficient fuel in the propane tank is also the main culprit for the malfunction of Nexgrill flame adjustment. So, you should check the fuel level in the tank regularly before using the grill. Here are ways you can check it:

  • At first, you have to turn off the burners.
  • Then disconnect the hose from the propane tank.
  • Check whether there is enough propane in it or not. Refill it up to 80%.
  • Finally, reconnect the hose with the propane tank and turn on the knobs.
  • Light the grill and low flame should be solved. 
  • If not, contact the nexgrill manufacturer.

      The most common reasons for the low flame on your gas grill are a faulty regulator, leaked propane from the tank, blocked gas orifices, and fuel level in the tank. First, try to trace out the main culprit behind the issue and then fix it.

      But before doing anything, it would be wise to contact the Nexgrill customer service center or your local Nexgrill dealer as your grill is brand new.

      Wish you a happy grilling.
