R Series Gas Range, RT Series Gas Rangetop Flicker Noise


  • Why is there a flickering sound when the surface burner is on medium setting?
  • Why does the flame seem to pulsate on medium heat; is this normal?


The R Series Gas Range and RT Series Gas Rangetop have an open surface burner design. The medium setting flame does have some pulsation (sounds similar to flickering) due to the large outer ring portion of the valve closing, while the inner ring is wide open. Gas may pulsate slightly with the regulator.

In addition, it is possible a different blend of liquid propane (LP) used to fill the propane tank may cause the sound during combustion on the gas range or rangetop.

  • This is considered normal operation.
