Brand:GE
Model Number: jgb630def1bb
Main Symptom:humming
What happens & when:oven or broiler only not range. Happens when flaming/heating/ and slightly after shut off (a few seconds). As if the hum correlates to the gas flow. Not the supply, already changed bottle; made no difference.
Error Code (if any)none
Parts or tests already tried:recently changed lower igniter. Noise was not present at that time. Does it regardless of lower igniter or upper igniter broiler being used. Heating is not affected so far.
