No zones detect any pan
The cooktop powers up, but every zone flashes, shows no pan, or drops out without heating.
Start here: Start with power, control lock, and basic pan compatibility checks.
Direct answer: When an induction cooktop says no pan or will not heat, the problem is usually the pan itself, the pan not sitting flat in the active zone, moisture or debris on the glass, or the wrong burner being selected. If one zone keeps missing good pans while the others work, that points more toward a failed cooktop induction burner or cooktop switch/control issue.
Most likely: Start with a magnetic flat-bottom pan on the correct zone, centered on a clean dry surface.
Induction cooktops do not heat the glass first and then the pan. They have to sense the right pan in the right spot before they will energize the zone. That means a warped pan, a pan that is too small, a wet surface, or a control input problem can all look like the same failure. Reality check: a pan that works on one zone can still fail on another if the size match is off. Common wrong move: testing with lightweight nonmagnetic cookware and assuming the cooktop is bad.
Don’t start with: Do not start by ordering a cooktop part just because the display says pan not detected. Induction units are picky about cookware, and that is the most common miss.
The cooktop powers up, but every zone flashes, shows no pan, or drops out without heating.
Start here: Start with power, control lock, and basic pan compatibility checks.
Other burners work normally, but one spot keeps rejecting pans that work elsewhere.
Start here: Compare that zone with a known-good pan and look for a single-burner hardware fault.
The zone starts for a moment, then flashes or cuts out as if the pan disappeared.
Start here: Check for a warped pan bottom, poor centering, or moisture between the pan and glass.
You have to tap controls several times, settings jump around, or the wrong zone seems to activate.
Start here: Clean and dry the control area first, then decide whether this is really a pan issue or a touch-control problem.
Induction needs magnetic cookware with a flat bottom, and many detection complaints come down to pans that are too small, warped, or only partly magnetic.
Quick check: Try a flat magnetic pan that a magnet sticks to firmly, and match its base size to the cooking zone.
A thin film of water, oil, or cooked-on residue can keep the pan from sitting flat enough for reliable sensing.
Quick check: Lift the pan and wipe both the cooktop glass and the pan bottom completely dry.
If the wrong element is active or the touch controls are misreading taps, the cooktop can act like it is not seeing the pan when the real issue is control input.
Quick check: Power the unit off, clean the control area, then deliberately select one zone and set a heat level again.
When one zone rejects multiple known-good pans while the rest of the cooktop works, the fault is more likely inside that burner circuit or its control path.
Quick check: Test two good pans on the bad zone and on a working zone for a clean side-by-side comparison.
Induction cooktops can look dead when the issue is actually control lock, wrong zone selection, or weak house power.
Next move: If the zone starts heating normally after a clean reset and proper selection, the problem was setup or touch input, not a failed burner. If the controls respond normally but the cooktop still says no pan or drops the pan, move to cookware and surface checks.
What to conclude: You want to separate a control problem from a true sensing problem before you go any deeper.
This is the most common fix and the least destructive one. Induction is unforgiving about pan material, flatness, and contact.
Next move: If the cooktop now detects the pan and holds heat, the issue was cookware fit, pan flatness, or poor contact on the glass. If the same zone still misses the pan, compare that pan on another zone before assuming the cooktop is bad.
What to conclude: A good induction pan on a clean dry surface should be detected quickly. If it is not, either the pan and zone are a poor match or the zone has a fault.
You need one clean comparison. Otherwise it is easy to blame the cooktop when the pan is the real problem, or buy cookware when one burner has actually failed.
Next move: If the suspect zone works with one good pan but not another, the cookware is the issue. If the suspect zone rejects multiple good pans while other zones accept them, the fault is likely in that cooktop induction burner or its control path.
Some pan-detection complaints are really control issues. If the wrong zone is activating or settings will not hold, the sensing circuit may not be the first failure.
Next move: If the controls become reliable and the zone starts normally, the issue was likely moisture, residue, or touch-panel confusion. If one zone still will not recognize good pans while the controls act normal, replacement of the cooktop induction burner or cooktop switch/control is the most likely next repair path.
At this point you have already ruled out the easy misses. The remaining fixes are inside the cooktop and involve line voltage, stored charge, and glass-top disassembly.
A good result: If the right internal part is replaced and the zone detects a known-good pan normally, the repair path was correct.
If not: If a confirmed part replacement does not restore detection, the fault is deeper in the cooktop electronics and professional diagnosis is the safer next step.
What to conclude: You have narrowed this to cookware, controls, or a specific induction zone. That keeps you from shotgun-buying parts.

Usually because the pan is not magnetic enough, the bottom is warped, the pan is too small for that zone, or the glass and pan bottom are not clean and dry. Start there before suspecting an internal failure.
Yes. Induction zones have different sizes and sensing patterns. A pan that barely works on a larger zone may not be detected on a smaller or differently sized zone.
Not necessarily the whole cooktop, but that is a strong sign of a single-zone problem if you have already tested multiple known-good magnetic pans and the other zones work normally.
Sometimes. If the issue is tied to confused touch controls or a temporary control glitch, shutting power off at the breaker and restarting the cooktop can help. It will not fix a warped pan or a failed burner component.
No. First clean and dry the glass and pan bottom and retest with a known-good pan. If the zone still drops detection, stop using that burner until you know whether the problem is cookware or an internal cooktop fault.
