All burners say no pan
No zone will heat even with cookware that used to work, or the controls act odd across the whole cooktop.
Start here: Start with power, control lock, and a full cooktop reset before focusing on any one burner.
Induction cooktop troubleshooting
Cafe Induction Range Pan Not Detected
Direct answer: When an induction range will not detect a pan, the usual cause is cookware that the burner cannot sense, the pan sitting off-center, or moisture and residue on the glass. If only one cooking zone does it with known-good induction cookware, that points more toward a failed cooktop burner or cooktop switch/control for that zone.
Most likely: Start with a flat magnetic pan on the correct-sized zone, centered on a clean dry surface, then test a second known-good pan on that same zone and on another zone.
Induction is picky in a very specific way: it has to see the right metal, in the right spot, over the right-size coil. Reality check: a pan that works on one induction zone can still fail on another if the base is too small or warped. Common wrong move: sliding a hot pan around on a wet or greasy glass top and assuming the electronics are bad when the zone just cannot get a clean read.
Don’t start with: Do not start by ordering a cooktop switch or tearing into the range. Most no-pan complaints turn out to be pan mismatch, pan size, or a simple surface issue.
If every zone misses every panCheck power, control lock, and whether the cooktop is showing other control problems before blaming a single burner.
If one zone misses pans but the others workUse the same known-good pan on that bad zone and a good zone back to back to confirm a zone-specific failure.

What pan detection failure looks like
Only one burner will not detect a pan
Other zones heat normally, but one zone flashes, beeps, or shuts off like no cookware is present.
Start here: Compare that zone with a working zone using the same pan. That quickly separates cookware issues from a bad cooktop burner or zone control.
Some pans work and some do not
A skillet may work, but a small saucepan or lightweight pan will not trigger the burner.
Start here: Check pan magnetism, flatness, and base size against the zone size before suspecting a failed part.
Pan is detected only if you reposition it
The burner starts only after sliding or rotating the pan, or it drops out during cooking.
Start here: Look for a warped pan base, residue on the glass, or a weak sensing problem on that zone.
Most likely causes
1. Cookware is not induction-friendly, too small, or warped
This is the most common reason. Induction needs a magnetic, fairly flat pan base with enough contact area over the sensing zone.
Quick check: Try a magnet on the pan bottom, then test a second flat pan that you know works on induction.
2. Glass surface or pan bottom is wet, greasy, or dirty
A film of oil, cooked-on residue, or moisture can keep the pan from sitting flat and can make detection inconsistent.
Quick check: Let the zone cool, then wipe the glass and pan bottom clean and dry with a soft cloth.
3. Wrong zone or poor pan placement
Small pans on a large zone, or a pan sitting off-center, often act like the cooktop cannot see the pan at all.
Quick check: Center the pan on the marked zone and test a pan whose base better matches that burner size.
4. Failed cooktop burner or cooktop switch/control for one zone
If one zone will not detect any known-good pan while the others work normally, the fault is usually in that zone's burner assembly or its control path.
Quick check: Use the same pan on a good zone and the bad zone back to back. If only the bad zone fails, the problem is in the cooktop, not the pan.
Step-by-step fix
Step 1: Make sure this is really a pan-detection problem
Induction ranges can look dead for reasons that have nothing to do with the pan, especially after a power blip or if the controls are locked.
- Confirm the cooktop has power and the display responds normally.
- Check whether control lock or a similar lockout is on, and turn it off if needed.
- If the controls seem glitchy, power the range off at the breaker for about 2 minutes, then restore power and retest.
- If the cooktop shows broader control trouble on every zone, treat it as a cooktop control problem rather than a cookware problem.
Next move: If the cooktop starts recognizing pans again after unlocking or resetting, you likely had a control-state issue, not a failed burner. If the controls respond normally but still say no pan, move on to cookware and surface checks.
What to conclude: This separates a true sensing complaint from a power or control issue affecting the whole cooktop.
Stop if:
- The breaker trips again after reset.
- You smell burning plastic or see sparking.
- The glass is cracked or chipped near the problem zone.
Step 2: Test the pan before you test the range
Most induction no-pan complaints are really cookware problems. You want to rule that out before opening anything.
- Use a magnet on the bottom of the pan. Weak or no pull usually means poor induction performance.
- Check that the pan bottom is flat, not domed or badly warped.
- Pick a second pan that you know has worked well on induction before.
- Avoid very small pans on large zones for this test.
Next move: If a known-good pan works and the original pan does not, the range is probably fine and the cookware is the issue. If two known-good pans both fail on the same zone, keep going. The problem is likely with that zone or the surface around it.
What to conclude: A pan that is magnetic but warped or undersized can still fail detection. Good cookware testing keeps you from chasing the wrong repair.
Step 3: Clean and dry the glass and retest with careful pan placement
Induction sensing gets unreliable when the pan is not sitting flat and centered. Grease film and moisture are common culprits.
- Let the cooktop cool fully.
- Wipe the problem zone with a soft cloth dampened with warm water and a little mild dish soap, then dry it completely.
- Wipe the pan bottom clean and dry too.
- Set the pan down centered on the marked zone instead of sliding it into place.
- Test the same pan on the problem zone, then on a working zone.
Next move: If the zone now detects the pan consistently, the issue was poor contact from residue, moisture, or placement. If the same pan works on another zone but still not on this one, you have a zone-specific cooktop problem.
Step 4: Compare one bad zone against one good zone
Back-to-back comparison is the fastest way to prove whether the failure lives in the cookware or in one cooktop zone.
- Use the same known-good pan on a working zone and note how quickly it detects.
- Move that same pan to the suspect zone and center it carefully.
- Try a second known-good pan on both zones.
- Notice whether the bad zone never detects, detects briefly then drops out, or only detects with repositioning.
Next move: If the suspect zone behaves normally with both pans, the earlier issue was likely pan fit or surface condition. If the suspect zone fails with every known-good pan while the good zone works, the cooktop burner or its cooktop switch/control for that zone is the likely repair path.
Step 5: Decide between a DIY part replacement and a service call
Once you have confirmed a zone-specific failure, the remaining work is internal electrical diagnosis or replacement. That is where guesswork gets expensive.
- If only one zone fails every pan test and the rest of the cooktop works, plan around that zone's cooktop burner first.
- If the zone responds erratically, drops pans in and out, or the touch response for that zone is also odd, include the cooktop switch/control for that zone in the diagnosis.
- Do not buy both parts at once unless you have already confirmed the failed component with service information and testing.
- If you are comfortable disconnecting power, opening the unit, and inspecting for obvious heat damage, loose connections, or a burned zone component, do that only with power fully off.
- If you are not set up for internal electrical testing, book appliance service and tell them one induction zone will not detect any known-good pan while the others do.
A good result: If inspection or service confirms the failed zone component and it is replaced, pan detection should return on that zone with known-good cookware.
If not: If the problem affects multiple zones or returns after a zone part replacement, the fault is likely deeper in the cooktop electronics and is better handled as a professional repair decision.
What to conclude: At this stage you have narrowed it to a real cooktop fault instead of a cookware issue, and you can move forward without blind parts swapping.

FAQ
Why does my induction range say no pan when the pan is on it?
Usually because the pan bottom is not magnetic enough, is too small for that zone, is warped, or is sitting on a dirty or wet glass surface. If the same pan works on other zones but not one specific zone, that zone likely has a cooktop fault.
Can a pan work on one induction burner but not another?
Yes. A small pan may work on a smaller zone and fail on a larger one, or a slightly warped pan may only be detected on some zones. That is why back-to-back testing on a good zone and the bad zone matters.
Does a dirty cooktop really stop pan detection?
It can. Grease film, cooked-on residue, and moisture can keep the pan from sitting flat enough for reliable sensing. It is a simple check, but it solves more of these complaints than people expect.
If only one burner will not detect a pan, what part usually fails?
After you rule out cookware and surface issues, the most likely repair is that zone's cooktop burner. If the zone also has strange touch response or control behavior, the cooktop switch or zone control becomes more likely.
Should I replace the control first or the burner first?
Not blindly. If the problem is limited to one zone and the controls otherwise act normal, the cooktop burner is the stronger bet. If that zone also has inconsistent control response, confirm the cooktop switch or control path before ordering parts.
Can I keep using the other burners if one zone will not detect pans?
Usually yes, as long as there is no cracked glass, burning smell, sparking, or breaker trip. If any of those show up, stop using the cooktop until it is repaired.
