No burners detect any pan
Every zone acts like the pan is missing, or the controls will not start heating at all.
Start here: Start with power, control lock, and a simple known-good magnetic pan before looking for a failed part.
Cooktop troubleshooting
LG Induction Range Pan Not Detected
Direct answer: When an induction burner will not see the pan, the problem is usually the cookware, the pan-to-burner size match, or moisture and residue on the glass. If one zone keeps missing good pans while the others work normally, that points more toward a bad cooktop induction element or cooktop burner control switch.
Most likely: Start with a magnetic flat-bottom pan on the right-sized zone, then clean and dry the glass and pan bottom completely.
Induction is picky in a very specific way: the pan has to be magnetic, flat, and sitting where the zone can read it. Reality check: even expensive cookware can fail this test if the base is warped or only partly magnetic. Common wrong move: sliding a hot pan around on a damp or greasy surface and then chasing a false no-pan problem.
Don’t start with: Do not start by ordering electronics or assuming every pan should work on induction. A lot of 'bad burner' calls turn out to be cookware mismatch.
If all burners miss every panCheck power, control lock, and whether the cooktop is showing other control problems before blaming one burner.
If only one burner misses pansUse a known-good induction pan on that zone and compare it to a working zone right away.

What this usually looks like
Only one burner will not detect pans
Other zones heat normally, but one zone flashes, beeps, or drops out with the same cookware.
Start here: Compare that zone with a working zone using the same pan. If the problem stays with one spot, focus on that burner hardware or its control.
Pan is detected only sometimes
The burner starts, then loses the pan when you shift it, lower the heat, or after a minute or two.
Start here: Check for a warped pan bottom, moisture, residue, or poor centering before suspecting the cooktop.
Only certain pans are not detected
One skillet works, another does not, even on the same burner.
Start here: Treat this as a cookware issue first. Induction needs a magnetic base and a size that matches the zone.
Most likely causes
1. Cookware is not induction-compatible or the base is warped
This is the most common cause by far. Induction needs a magnetic base close to the glass, and a bowed pan can break that coupling.
Quick check: Touch a fridge magnet to the center of the pan bottom. If it barely sticks or only sticks around the edge, that pan is a weak candidate.
2. Pan size does not match the induction zone well
A small pan on a large zone, or a pan sitting off-center, can make the cooktop act like nothing is there.
Quick check: Move a known-good pan to the problem zone and center it carefully. Try a pan whose base is closer to that zone's size.
3. Moisture, grease, or debris between the pan and glass
A wet paper towel mark, oil film, or cooked-on residue can interfere with stable pan sensing and make the burner drop out.
Quick check: Let the surface cool, then wipe the glass and pan bottom with a damp cloth and dry both fully.
4. One cooktop induction element or cooktop burner control switch is failing
If one zone repeatedly misses known-good pans while the rest of the cooktop works, the fault is usually local to that burner circuit.
Quick check: Use the same pan on a working zone and then on the bad zone. If the pan works everywhere except one spot, the burner hardware is the stronger suspect.
Step-by-step fix
Step 1: Prove the pan is the right kind before you touch the cooktop
Most no-pan complaints are really cookware problems, and this is the fastest way to avoid chasing the wrong repair.
- Use a simple magnetic flat-bottom pan if you have one, not a griddle, wok, or pan with a rounded or ridged base.
- Test the pan with a household magnet on the center of the bottom. Strong grab at the center is what you want.
- Look across the pan bottom at eye level. If it rocks on the glass or looks domed or dished, set it aside for now.
- Try that same known-good pan on another induction zone first so you know the pan itself can be detected.
Next move: If the known-good pan works and the original pan does not, your cooktop is probably fine. Use different cookware on that zone. If even a known-good magnetic pan is not detected, keep going. The issue is likely setup, surface condition, or the burner itself.
What to conclude: You are separating a cookware mismatch from an actual cooktop fault.
Stop if:
- The cooktop glass is cracked.
- You smell burning insulation or see sparking.
- The pan bottom is damaged enough to scratch or chip the glass.
Step 2: Match the pan to the right zone and center it carefully
Induction zones are less forgiving than radiant burners. A pan that is too small, too large, or off-center can act like it is invisible.
- Place the known-good pan on the problem zone only after the pan and glass are dry.
- Center the pan over the marked cooking area instead of letting the handle weight pull it off to one side.
- If the problem is on a large zone, try a pan with a base closer to that zone's marked size.
- If the cooktop has multiple zones, move the same pan to a working zone and then back to the problem zone without changing anything else.
Next move: If the burner starts heating once the pan is centered or better matched, the cooktop is reading normally and the issue was pan placement or size match. If the same pan works on other zones but not this one, the problem is now leaning toward that burner's sensing or control parts.
What to conclude: A zone-specific failure is more likely than a whole-cooktop problem when one spot consistently misses a known-good pan.
Step 3: Clean and dry the glass surface and pan bottom
A thin film of grease, starch, or moisture can make pan detection unstable, especially when the burner starts and then drops out.
- Turn the cooktop off and let the surface cool fully.
- Wipe the glass with a soft cloth, warm water, and a little mild dish soap if needed.
- Dry the glass completely with a clean towel.
- Wipe and dry the pan bottom too, especially any oily ring or water spots.
- Check for cooked-on residue or a rough spot under the pan that keeps it from sitting flat.
Next move: If the burner now detects the pan reliably, the problem was surface contamination or trapped moisture. If cleaning changes nothing and the same zone still misses good pans, move on to control behavior and burner failure checks.
Step 4: Check for control lock, touch-control trouble, or a broader power issue
If all zones are acting dead or inconsistent, the problem may not be the pan sensor at one burner. It may be the controls or incoming power.
- Make sure the cooktop is not in control lock mode and that the controls respond normally to touch.
- Try powering the unit off at the breaker for a few minutes, then restore power and retest with the known-good pan.
- Watch whether the display responds cleanly or misses touches, flashes, or throws repeated errors.
- If no zones detect any pan and the controls seem weak or partial, note whether other range functions also act odd.
Next move: If a power reset restores normal pan detection, the issue may have been a temporary control glitch. If the controls are normal but one zone still will not detect a good pan, the local burner parts are the likely path. If the whole top is unresponsive, service is the safer next move.
Step 5: Act on the pattern you found
By now you should know whether this is bad cookware, a dirty contact surface, one failed burner circuit, or a broader control problem.
- If only one zone fails with known-good pans and the rest of the cooktop works, plan on a cooktop induction element or cooktop burner control switch for that zone after fitment is confirmed.
- If all zones miss pans or the touch controls are erratic, stop at diagnosis and schedule appliance service rather than guessing at internal electronics.
- If the issue follows one pan from zone to zone, replace the cookware, not the cooktop parts.
- Before ordering any part, verify the exact zone involved and compare symptoms one more time with a known-good pan on a working zone.
A good result: If replacing the bad cookware or correcting the zone-specific part fixes detection, the burner should recognize the pan quickly and stay engaged without dropouts.
If not: If a confirmed zone-specific repair does not restore detection, the fault is likely deeper in the cooktop control electronics and is better handled as a service call.
What to conclude: You have narrowed the problem to the right repair path instead of swapping parts blindly.

FAQ
Why does my induction range say no pan when the pan is sitting right there?
Usually because the pan bottom is not magnetic enough, the base is warped, the pan is too small for that zone, or the glass and pan bottom are wet or greasy. Start there before suspecting a failed part.
Can a pan work on one induction burner but not another?
Yes. A pan that is borderline for induction may work on one zone and not another, especially if the burner sizes are different. That is why using one known-good pan across multiple zones is such a useful test.
How do I know if the problem is the pan or the burner?
Use the same known-good magnetic pan on a working zone and then on the problem zone. If it works everywhere except one spot, the burner side is the stronger suspect. If the problem follows one pan from zone to zone, it is the cookware.
Will cleaning the cooktop really fix pan detection?
Sometimes, yes. A thin film of grease, starch, or moisture can cause unstable sensing, especially when the burner starts and then drops out. Clean and dry both the glass and the pan bottom completely.
What part usually fails when only one induction burner will not detect pans?
On a zone-specific failure, the usual repair path is the cooktop induction element or the cooktop burner control switch for that burner, depending on how the controls behave and what the comparison tests show.
Should I reset the range at the breaker?
A breaker reset is reasonable if all zones suddenly stopped detecting pans or the controls are acting odd. If the problem comes right back, especially on just one zone, a temporary reset is not the real fix.
