What's the best way to clean gas stove top pieces?

Generally the issue with this is not that you don't have the correct pressure but the Burner top hat that displaces the gas is dirty.
Remove the metal rack to expose the burner itself. Make sure it's not been used recently to prevent a burn. Carefully lift the little burner cap off. This is the piece with all the holes in it the flames come from. They generally just sit on top. You will need a flashlight, know look in the little slits below the cap for cleaning material buildup. A tooth pick or a stiff bristle tooth brush can be used to clean these little slits.
The cleaning products used to clean stove tops tends to leave little trace amounts of surfactants that over time block these little slits and prevent the escaping gas to flow towards the ignitor preventing the burner from lighting.
Once you have this clean replace the top. Put the pan grate back on and try to relight the stove.
I am sure this should fix you issue. If it doesn't please let me know and I can give you some other tips to try.

What I would try. Assuming the "burners" means the cast iron assemblies on top of the stainless steel, remove them to an area outside. Perhaps on a piece of plywood, and clean them with oven cleaner. Grease may drip off them, so a deck or driveway are unacceptable. Wear gloves and watch splatters. Wash thoroughly with fresh water before reusing. Beware. Caustic chemicals can discolor stainless

Some of the pieces were still wet. I took it all apart & dried everything & the clicking stopped.

You must replace those controls. Cleaning or loosening them up would be temporary at best and the next time they stick it could be in the open position. Safety first...Eric

glass cleaner WITH ammonia, and a small toothbrush works well. mop up with an old washcloth, rinsing often. for pieces which have gummy residue, and which can be removed to the sink for soap and water finsing afterwards, try GooGone.

I have a MGR4452BDW. The burners turn 1/4 turn, then pull out. Yours should too.

I got this problem yesterday. My 6-month old GE range/stove top was being cleaned by a cleaning lady and suddenly, the igniters started clicking nonstop. I had to shut down the circuit breakers. I googled the problem, and it seemed clear that the "spark switches" got moisture on them. The best site which described this is: http://www.appliance411.com/archive/25012_ge_gas_cooktop_not_working_.shtml

Some people said you could dry them with a blow dryer, and others said you need to replace these switches (which is not too expensive, but takes some time/skill). I was hoping against this, so I tried something along those lines: I removed all the parts of the stovetop - the grill, the "cap", the metal funky piece, etc. until there was nothing but the surface of the stove and holes going down to the igniter area. Then, I took an electric fan and kept it pointed at the stovetop all night long. After about 10 hours, I turned the circuit breaker back on. No more clicking! And the burners all work! So, I think I essentially did the "hair dryer" solution, but did it more longterm without having to watch the clock to see if I did it long enough. Anyway, I don't normally post these things, but this discovery really helped me and I hope it helps someone else!

your gas jets are dirty.. clean them with a toothbrush (after everything is cooled down).. you can use the selfclean to clean the iron pieces that cover the burners..

be careful with kitchen aid self cleaning.. there is a known issue with the thermal fuses blowing quite easily on most self cleaning cycles..

good luck

The burner are fixed only maintenace are to clean burner /clean holes and edge in order flow of gas good performance.At the back if you want make more good performance of your top burner clean the nozzle where the air and gas mix . Clean the nozzle w/fine niddle /sometime if will corrode with rust and dust to struck flow of gas.

Try carefully cleaning around the ignitors. Also clean hole in burners. Clean the holes closest to ignitors. This can be caused by a crack in ignitor, this requires replacement.
