One burner on my cooktop will not turn off. - Jenn-Air 30 in. CCE3401 Electric Cooktop

What do you mean by "all four burners turn on"
Some electronic ignite systems turn on on all the burners, But just the SPARK not the gas part of the burner.
Is this what you are describing?.

The part you need to replace is the switch. The switch is housed under the top and connects to the dial you are turning.
The switch for the dual burner is 12002125, and 74011242 for the single burner.

The single burner switch runs about $20.00 and the dual runs about $50.00 for the parts

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.

sounds like you have a bad switch. maybe on the large burner.. some of those switches can be replaced without the whole harness.

It's an ignition switch. don't change the burner cartridge.

Check the power plug is their any separate plug on it / if none check the control panel some switch to power on .
