The short answer
On a Electrolux cooktop, a cooktop control that is not behaving usually comes down to a blocked control cooling path rather than anything deeper in the machine: the control under the glass is cooled by air drawn through a vent, and a drawer or a liner against that vent shuts zones down on temperature. That keeps it an owner check first, not a service call. Start here: check that the vent under the cooktop is clear, because on this platform a hot control pocket produces most of the fault behaviour.
What you are seeing
- A single zone that does nothing while the others work
- A whole surface that will not respond to any touch
- Zones that change setting on their own
- A zone that works and then shuts down after a while
- A lock indicator the owner did not set
- Not this fault: A zone that heats weakly, which is a power or cookware problem rather than a control fault
- Not this fault: An oven fault on the same appliance, which is a separate circuit
- Body: Electrolux builds this cooktop as a glass touch-slider control over separate power boards, with a cooling fan under the glass and thermal limits on each zone. That architecture decides which of these you see first.
- Also check note: If these fit better, the fault is a different one.
Likely causes, in order
- A blocked control cooling path — Why this rank: The Electrolux cooktop draws cooling air through a vent under the glass, and a drawer or a liner pressed against it overheats the control.
- The touch slider losing calibration — Why this rank: The touch slider loses calibration when moisture or heat reaches it, giving zones that change setting on their own.
- A zone power board — Why this rank: Electrolux splits the power boards from the touch control, so a single dead zone is a power-board fault rather than a control fault.
- The control lock engaged — Why this rank: A long press on the lock pad disables the whole surface.
- Cookware the zone cannot use — Why this rank: An induction zone will refuse a pan that is not magnetic or is too small.
- Body: Ranked for a Electrolux cooktop specifically.
What to check, in order
- Body: The order follows the ranking, and the ranking follows the platform. First: open the space under the cooktop and check nothing is pressed against it. It goes first because the Electrolux cooktop draws cooling air through a vent under the glass, and a drawer or a liner pressed against it overheats the control. Second: wipe the glass completely dry and try again. With the first check clean, this is what the Electrolux platform makes next most likely. Third: note whether one zone is dead while the others behave. Only after those three is it worth reaching for the control lock engaged: it costs more to get at, and it does not explain the first three coming back clean.
Checks you can make
- Open the drawer or cabinet under the cooktop and check that nothing is pressed against the underside. Blocking the cooling path there is the most common cause of odd control behaviour. — Tools: none — Time: about five minutes
- Hold a fridge magnet against the base of the pan. An induction zone cannot heat a pan the magnet will not grip, and a pan too small for the zone will not be recognised either. — Tools: fridge magnet — Time: about two minutes
- Wipe the glass completely dry and try the controls again. A slider that misreads with a damp cloth on it is telling you moisture is reaching the sensor layer. — Tools: dry cloth — Time: about five minutes
- Wipe the whole glass surface completely dry with a clean cloth and try the controls again. Touch controls read a wet cloth as a continuous press and lock out. — Tools: dry cloth — Time: about five minutes
- Body: Stop at the first step that would need a meter on live terminals or a sealed assembly opened.
Before you open anything
Safety
Switch the appliance off at its breaker before anything is opened, and let the surface cool completely. Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. A cracked glass surface must be taken out of use immediately. A crack lets liquid reach the electrics underneath and the surface is no longer structurally sound. Let the surface cool fully before cleaning or testing. Residual heat on a smooth top is not visible.
When to call
The line is not difficulty, it is what the next step costs and risks. Call when: one zone is dead while the others behave normally after cookware and lock have been ruled out the control cuts out repeatedly once the surface is hot, after the cooling path has been cleared

What this page omits
This is generalized information: it ranks causes for the Electrolux cooktop range as one platform, not for a single model. Where a page exists for your specific model it is the more specific one and takes precedence over this. Read your model number off the rating plate before ordering any part.
