Gas Burner Flame Level Incorrect

Gas Burner Flames are too High or Low, Uneven, Flickering, Yellow, or Noisy on your Jenn-Air Cooktop

If your gas burner flames are not normal, check to make sure the burner ports are clean. 

To clean the ports: Clean clogged burner ports with a straight pin, needle, or small-gauge wire as shown.

  • Do not use a wooden toothpick, it can break off and prevent proper gas flow. 
  • Do not clean in the dishwasher, detergent can clog gas ports.
  • Do not enlarge or distort the port, this will lead to unstable flames.

Is the burner base and burner cap positioned properly? 

  • Flame spreader or burner base must be seated on the burner base to light and perform properly.  
  • Burner cap must be seated properly on the correct flame spreader or burner base to light and perform properly.

Typical burners shown below:

NOTE: Always keep the burner cap in place when using a surface burner. A clean burner cap, especially the bottom of the cap, will help avoid poor ignition and uneven flames. Always clean the burner cap after a spillover and routinely remove and clean the caps.

  • Be sure the correct burner cap is on the correct burner base.  The burner base and the underside of the burner cap may have a mark indicating which burner cap and burner base match as shown below.

  • Reinstall the burner cap; making sure the alignment pins(if present) are properly aligned with the burner cap as shown below. 
  • Burner cap should fit flush with burner base and have very little side to side movement.  



Does the surface burner make a popping noise?

The burner could be wet from a spillover or from cleaning.  Allow the burner to completely dry and replace the burner cap.  You can speed up the drying process by blowing cool air on the area using a hair dryer.

Is propane gas being used?

Compare the flame to the illustrations below. If the flames look like A:

  • A burner port (hole) may be clogged.  
  • Check to be sure the burner caps are positioned correctly.
  • If LP (propane) gas is being used, the cooktop may have been converted improperly, call for service. 

Normal flames look like B or C.
