Panel is lit but no buttons respond
The display has power, but every touch key seems dead or the unit just beeps.
Start here: Start with control lock, moisture, and surface contamination on the touch area.
Direct answer: If your cooktop touch controls are not working, the most common causes are control lock being on, moisture on the glass or control area, a power issue, or a failed cooktop touch control assembly. Start with the lock and surface checks before opening anything up.
Most likely: On most touch-control cooktops, a wet control area, a stuck lock mode, or a brief power glitch is more common than a bad internal part.
First figure out whether the whole cooktop is unresponsive, only one burner control is dead, or the display works but will not accept touch input. That split tells you whether you are dealing with a simple surface issue, a power supply problem, or a failed cooktop touch control component. Reality check: touch panels often act dead when they are just wet or locked. Common wrong move: scrubbing the control area with too much cleaner and driving moisture into the edge of the panel.
Don’t start with: Do not start by ordering a cooktop control board just because the panel is dead. A locked panel or damp touch strip fools a lot of people.

No display, no beeps, and no burner response at all.
Start here: Start with the breaker, power supply, and whether the cooktop recently lost power.
Some touch keys work normally, but one burner or one side of the panel does not.
Start here: Start with a careful surface check, then suspect a failing cooktop touch control assembly or cooktop switch for that section.
The panel beeps randomly, changes heat levels, or works only after repeated touches.
Start here: Start with moisture, residue, heat buildup, and a damaged touch surface before assuming an internal board failure.
A locked panel often still lights up and may beep, but it will ignore normal burner commands.
Quick check: Look for a lock icon or press and hold the lock key area for several seconds with dry hands.
Touch controls read through the glass. Water film, greasy residue, or cleaner trapped along the edge can make the panel ignore input or act erratic.
Quick check: Dry the entire control area thoroughly, especially along the front edge and around the touch icons, then try again.
If the whole unit is dark, a tripped breaker or weak power feed is more likely than every touch key failing at once.
Quick check: Check for a tripped double breaker and see whether the cooktop clock or indicators come back after resetting power once.
When the panel is clean, unlocked, and properly powered but one area or the whole touch interface still will not respond, the control component itself becomes the likely fault.
Quick check: Compare which keys respond and which do not. A repeatable dead zone points to a failed control component, not a random user error.
This is the fastest safe check, and it solves a surprising number of dead-touch complaints.
Next move: If the controls respond normally after unlocking or resetting, you likely had a lock mode or temporary control glitch, not a failed part. If the panel is still dead or only partly responsive, move to the surface and moisture check.
What to conclude: A working panel after this step points to a software-style hiccup or lock feature, not a hard part failure.
Touch panels are sensitive to water film, grease, and cleaner residue, especially near the front edge where spills collect.
Next move: If the panel comes back, the issue was surface moisture or residue interfering with the touch sensors. If the controls are still dead, separate a whole-unit power problem from a failed control section next.
What to conclude: A panel that improves after drying usually does not need parts. A panel that stays dead after a proper dry cleanup needs deeper checking.
A dark cooktop and a lit-but-dead cooktop are different problems. You do not want to chase touch parts when the unit is not getting proper power.
Next move: If power restoration brings the cooktop back and it stays stable, the issue was likely a power interruption rather than a failed control part. If the breaker is fine and the failure pattern is repeatable, the diagnosis is moving toward a failed cooktop control component.
Before buying parts, look for field clues that separate a worn control from a broader wiring or heat-damage problem.
Next move: If you find a clear dead section with no broader damage, you have enough support to consider the matching cooktop touch control assembly or cooktop switch. If you find heat damage, burnt wiring, or no clear pattern, stop short of guessing and plan for appliance service.
By this point you should know whether you have a simple touch-control failure or a larger electrical problem that is not worth guessing at.
A good result: If every touch key responds normally and each burner starts and adjusts heat correctly, the repair path was right.
If not: If the new control part does not restore operation, the fault is likely deeper in the cooktop's internal power or control system and needs professional diagnosis.
What to conclude: A successful repair confirms the failed control component. No change after a supported part replacement usually means the problem is upstream or in internal wiring.

That usually points to control lock, moisture on the touch area, or residue on the glass rather than a dead cooktop. Dry and clean the control strip first, then try unlocking it.
Yes. Even a thin film of water or cleaner can confuse touch sensors. Dry the entire control area, especially the front edge and around the icons, before assuming a part has failed.
Not always. A single dead section often points to a failed cooktop switch or one failed area of the touch control assembly, especially if the rest of the panel works normally.
Yes, once. A brief power reset can clear a control glitch. If the breaker trips again or the cooktop stays dark, stop there and treat it as a power or internal electrical problem.
It is worth considering when the panel has power, the control area is clean and dry, the lock is off, and the touch interface still will not respond in a consistent way. If the cooktop is dark, trips the breaker, or shows burnt wiring, service is the better next step.
