Where is the grease trap located

The spark module is in the ignition circuit for the gas burners. When a burner control knob is turned to the Lite position, it provides voltage to the spark electrodes on the gas burners. If the spark module fails to provide the electrodes with voltage, then it should be replaced.

Cleaning or replacing the grease filters in downdraft vent hood

Try soaking in hot soapy water that you've dropped several denture cleaning tablets in. That's helped me get some tough stuff off, or at least loosened up enough that some elbow grease and a scrubbie can finish off the job.

Put them in the oven and run the self clean cycle

Oven cleaner. That stuff is second only to industrial grade hydrogen peroxide

Batender's Friend. That stuff is amazing!

Good Luck

Try Sears Parts & Service. I don't know the cost.

check to see if the burners are free of deposits from carbon and grease build up. The tiny holes in the burners get clogged with grease and carbon.

sounds as if they are jammed which would req.,greasing with grathite grease , i assume that they can not be pushed down & turned.

burner 1 is the tap assembley reqs., greasing with graphite grease.
ignition depending on model this is correct.

the discoloration is from the heat. you can buy a stainless steel cleaner or use simple green for the grease.

Greases lightning is a great cleaner for cooktops and work great on the grease filter it is sold at most stores. Be careful however when cleaning around the control knobs. They do have a rubber dust cover over each switch but if any fluid drips past it and into the switch it could short out the control.

Hi, I assume we are talking about a flat glass top. First the bad news. using any abrasives will permanently scratch the glass hence the dull spot. You can however make it look a little better. Grease spots and the like can be removed with a flat razor blade scraper which needs to be held flat to avoid the corners making scratches. Use any good glass/ceramic cooktop cleaner ( which is the ONLY cleaner you should ever use ) (available in your local grocery diy store and some hardware stores). The cleaner is a thick liquid, put about a dime size drop on each burner area and use a paper towel to buff out the finish like waxing a car. Once it looks clean flip your paper towel over and shine the top to like new. Good Luck!
