How do i fix a squeaky control knob on a ge downdraft cooktop?

Can you get to the switch terminals and try jumping them out with a piece of insulated wire? That would tell you if the switch is defective (my suspicion). Please be careful not to touch any live terminals - only the wire insulation you use for the jumper.

You probably have button or a knob to press to get ignition if there is a bit of gunk stuck in there it will not come out again, you need to remove the knob and clean out whatever is in there.

Sorry to read about your problem, I hope this helps you out.

their is no cleaning of contacts, they are sealed units..have to replace the switch,
you have to remove the entire range from the counter top..will take 2 people

I tried to help you. Please help me and Rate/Vote on my response, thanks and good luck

You need the switch for that burner. The contacts inside are stuck together. You will need to pull the unit and separate the glass from the lower body to access it. To get the right switch you need full model and serial number located on a plate at the bottom of the unit.

Your ability to perform this is dependent on how mechanical you are. The Whole unit must be removed from the counter opening and the base unscrewed from the glass, remove knobs before disassembling. For someone mechanical this is not difficult. De-energize whole unit first.

Once the two pieces are separated the remainder is mechanically easier. Disassemble the box on right containing the switches and replace the correct one. Reverse the process for reassembly. Good Luck

if the knobs wont turn, the cooker needs to be serviced by a gas engineer the gas taps are seized they need gas tab grease

clean the knob control by using vaccium,pull the knobs then clean it.make sure how to remove the knob,same position to returrn the knob

NO METAL KNOB FOR THAT MODEL COZ IF USE METAL EVERY TIME U USE IS HOT THATS WHY DESIGN FOR PLASTIC,MUCH BETTER TO U REMOVE THE KNOBS AFTER U TUNN ON THE HOBS TO LESS MELT THEN RETURN IT IF U TUNR IT OR ADJUST.

ouch, sounds as ifthe valve has frozen up, replacing hte valve would be the solution

Contact your local gas company and turn off the gas to the unit.

appliance repair and yes you can fix it you likely need an infinite switch
