Hi, I have a Jenn-air jgc8536 gas cooktop and 2 of the knobs inexplicably melted. Please help! Rick Fern

Hi,

Your problem could be or probably is with the regulator...not enough gas pressure...

Hi,
Here is a tip that I wrote to help people troubleshoot problems with their cooktops not igniting.

spark igniter stays on after burners lit. can you help?

What color is your cook-top? The stainless model may have actual steel knobs.. End your model number with "s" when looking for the parts..
If you have stainless and they are still plastic "stainless look" knobs then call the manufacturer as they would be the only ones to be able to determine if there is a metal knob available for your unit.
Good luck!

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

Hi the spark box is shorting out have put a new one in or the ignition switch is faulty

One burner doesn't consistently light. Igniter sparks but not the same as the other - "good" burners spark at top of igniter and moves around to light, "bad" burner sparks toward the bottom and doesn't move much. I can use the burner by lighting with a match and it works fine. Have tried cleaning with a toothbrush without much success

Jenn Air uses a reignition system on their gas cooktops.It is very important that you have a well grounded recepticle. Please check that and please get back to me.

it will be due to the lack of lubricant inside the fan and a part of the cylinder can be broken due to wear and tear u open that assembly and verify it if everything ok put a little grease or oil and close it

I have this cooktop and it is hands-down the worst. That clicking sound is the spark missing the mark because of a crack or chip in the ceramic igniter. Damage is caused by the ceramic heating too quickly. Especially when the house is cooler in winter, or in air conditioning. I had a Jenn Air repair guy in to replace them before the warranty ran out and he said this happens with every single one of these models with the ceramic igniter. Also, one of the knobs on the front by the medium burner got so hot it melted. He gave us a new one. He had a whole box of them in his truck! He told us the design was inferior and that Jenn Air uses a different igniter for higher end models because of this problem, but won't re-engineer the lower end units because it's cost prohibitive. Even with the repairs they cover for the first year, they recoup in charging for service the second year, than profit on the repair and/or replacement charges for the parts every year after that. All the parts sold are OEM--no after markets, so, at roughly $27 a pop for each igniter, they make out pretty good. Oh, and the burner knob is melted again. What a bunch of scamsters. I will never give them my money again and am shopping for a new cooktop. I left a good review at bizrate for this cooktop.
