Humming noise we have a four burner gas cooktop--when you put on a burner it makes a loud humming noise --sometimes when you ignite the other burners the noise goes off but sometimes it does not and you must cook with the awful noise. A friend told us it has to do with the shut off valve or the place where the gas comes up and arms off to the four burners---it vibrates or there is something loose or caught in there--a tech. guy is coming out this week to look at it hoping it can be fixed--do you have any other suggestions?

SOURCE: Dead burner on kitchenaid gas cooktop?

it is strange that you have no gas and no spark! if you held a match to the burner and turned the burner valve on it would lite di spite a failed ignitor,but for it not to lite, the burner valve[its what the knob attaches too] would have to be blocked[thats rare]or ........i got it .....the knob is broken.thats the only thing the burner valve and the spark ignitor have in common.try a knob from another burner................again.you have spark,because others are working.spark on troubled burner would work if valve blocked at orifice outlet,and if spark failed you would still get gas they work independent of each other,[but in unison].thats why im thinking knob.its the item that works both .when you turn the knob it opens the gas valve and as the gas valve rotates by turning the knob it activates or turns the spark switch so it closes the curcit allowing the electricty to the spark moduel.hey i hope that helps a little. God bless ,tom

SOURCE: spark igniters on the burners fire continuously

When cleaning, if the control switches get damp, they will react as you describe.
Unplug the appliance, use a hair dryer and attempt to dry the switches.
Leave it unplugged overnight and try them again tomorrow.
They will eventually dry and be OK.

SOURCE: One burner igniter fails to spark after getting wet

Each burner has its own switch to direct current to the igniter. It appears that one of the four switches burned or shorted out, while the other three survived the flood. These switches are replaceable, so that's how I'll fix the problem.

Hi,

Here is a tip that I wrote that will help figure out why the burner spark keeps on clicking...
