Cooktop on/off buttons don't work (not locked)

The L indicates that the child lock feature has been enabled. This ensures that the burners do not function while you clean the cook top and that a child can't turn on any burners.

The procedure depends on your cook top model. For some induction models, to toggle the child lock feature off, press the front right burner zone display and the booster function key (circle with a solid circle inside on the right of the selector zone) simultaneously. Then press the front right burner zone display again until the L disappears from the display.
See page 23 of the manual for the Delonghi DEIND804 available here: https://www.appliancesonline.com.au/public/manuals/Delonghi-DEIND804-Induction-Cooktop-User-Manual.pdf .

For an electric ceramic cooktop DTCH808, to turn off the child lock completely, press the bottom right + in a circle and the - in a circle (in the center surrounded by 4 of the + in a circle areas) simultaneously and then release the keys. Press the - in a circle again. See page 21 of the manual here: https://www.delonghi.com/Global/InstructionManuals/EN/EN-DTCH80B_im.pdf .

I hope this helps. Please add a comment with the model of your Delonghi cook top if these instructions do not apply to your cook top.

Hi,

Here is a tip that I wrote to give details about why your cooktop will not spark to light the burners..

Cooktop Range Stove spark ignition does not work

Some times a breaker can be partially tripped and not visible . You should try turning the breaker off and on several times.

always unplug electricity before attempting to repair on any electrical appliance

OK, the best action is to call for service, if the unit was just installed, and purchased. This unit should be covered at this time, by the manufactures warranty, or store 30 day warranty. This repair should be free. The culprit will be a faulty spark ignition switch, and module. Testing is required. Once this switch, or(module), is replaced, the unit will operate correctly.

I have a JEC9536ADB electric Jenn-Air Cooktop. We replaced the class top and now the knobs are all spliting and won't work. 2 of the main burners will only heat in the "high" position? What do I need to replace?

sounds like the air /gas mixture is off.look at where the burner meets the gas valve (the knob) under the grates and play with the adjuster turn it slowly while the burner is on and this will change the value of the air/gas mixture good luck

well usually you have to remove the knobs. thentake all of the caps off of the burners. sometimes there are scres that hold the burner caps on. make sure you turn the power off. Then after you have done this the glass should come right off. If not there may be screws under the cooktop. Do these first steps and let me know how it goes.

lowly is it the left burners that won't lite? I only ask as depending on the model some of the Thermador cook tops had simmer control burners. This is a 3 part system on the burners. 1 a simmer control, 2 electric solenoid, 3 potentiors. When you turn on the burner the potentior tells the simmer control to send power to the gas solenoid. At the same time the unit will spark. If your unit has extra low on the left 2 burners then you have this system. The usual problem in the potentior. Hope this helps.

The cook top should be bolted to the counter. Look under and look for brackets that attach the bottom of the cooktop to the sides of the counter. and also the model number should be somewere underneath. If you can get me the Model number I can get you the maintenance manual in PDF format.
