My jen air electric cooktop jd 8430 comes on but shuts off after a few seconds then comes on again, all of the burners do it and jus started doing it today

Have you tried turning it upside down and removing any covers.

Hi,

I am assuming your cooktop is electric and your have a glass top, if so the burners sensor is bad and you might need to replace the burner. Again before buying anything and for me to help you, I would need a full model number. Some model have plate sensors and with no plate/pot burner cycles. Most of the time I find the sensor in the burner cant detect the heat and this ends up being a safety issue to protect the unit. All this information is based on the premise you have an electric cooktop and a glass surface.

I hope this helps.

its not suppose to stay on for long time...its suppose to recycle...set it at high heat all burners should come on for few seconds and then go off for few seconds...small burner do faster then bigg ones

hi...the unit is have an waranty call the service center to check & replace the part.

tnx gerbee

Throw your circuit breaker that leads to this unit for a few seconds, then reset the breaker This unit is very sensitive to power fluctuations.

Someone suggested the flapper needs replacing.
Thanks for your help.

your ignition button is sticking down after you press it to light the burners, give it a few taps and clean underneath the button.

The cook top is attached to the wood frame by brackets, just remove the screws and the electric connection, make sure the power is off from the main box, it's a 220 volt wiring and then just lift the top off. to remove the glass, look around the edges and you should see some small screws, just remove them and the glass should lift off.

these are cartridge elements corrrect? try reversing the cartidges, now the front small will become the rear small . does it not work in this position? and the newly placed front burner work?? this will determine if the proble lies within the cartridge or the switches

No recalls that I know of.  The switch for that burner has shorted and will need to be replaced.  It will be fine once it is repaired.
