Induction cooktops behave nothing like gas or electric coil models. The cooking surface stays cool. The pan heats directly through electromagnetic induction. No flame, no glow. Which makes troubleshooting an unfamiliar process when something stops working — sometimes a burner won’t turn on, sometimes it powers up but won’t recognize the pan, sometimes the display shows an error code you’ve never seen before.
A good share of “induction cooktop not working” issues turn out to be a wrong pan, a stuck touch panel, or a power problem rather than a failed component. The rest — coil failures, power module damage, control board issues — need a tech with the right equipment. If you’d rather skip ahead and have a pro look at it, appliance repair Jacksonville FL specialists handle induction cooktops from Bosch, Miele, Thermador, KitchenAid, Wolf, Samsung, GE, and Frigidaire weekly.
How Induction Works (Briefly)
Underneath the glass sits a copper coil. When you turn on a burner, an alternating current runs through that coil and creates a rapidly changing magnetic field. If a magnetic pan sits on the glass above it, the field induces eddy currents in the pan’s base, which heats the pan directly. No pan, no heat. No magnetism, no heat. That’s why induction units behave so differently when something fails.

Quick Checks to Run First
- Magnet test on the cookware. Stick a magnet to the bottom of the pan. If it doesn’t hold firmly, the pan isn’t induction-compatible. Aluminum, copper, and most non-magnetic stainless steel won’t trigger the burner.
- Check pan size and centering. Most induction burners need the pan to cover at least 75% of the heating zone. Small or off-center pans can fail to register.
- Reset the breaker. Induction cooktops run on a dedicated 240V circuit. Breakers can sit halfway tripped — cycle them fully off and back on. Power outages often require a reset.
- Clean the touch panel. Water, oil splatter, or a damp cloth on the controls confuses the capacitive sensors.
- Disable the control lock. Look for a key or padlock icon. Hold for three to five seconds. Bosch, Miele, and KitchenAid units engage child lock more easily than people expect.
1. Only One Burner Stopped Working
Each induction zone has its own coil, power module, and sensor. When one stops while the others keep working, the cause is isolated to that specific burner — most often the coil itself or the dedicated power module beneath it. You’ll usually hear no activation sound when that burner is turned on. Both parts sit under the glass and require lifting the cooktop to diagnose.
A multimeter test confirms which component lost continuity.
2. Cooktop Powers On But Won’t Recognize the Pan
If the display lights up, the burner activates, and a “no pan detected” icon appears — or the burner refuses to start with a pan on it — the issue is pan detection. Even some “induction-ready” pans lose their magnetic responsiveness over time if the base warps from heat. Bowed bottoms are a frequent culprit. If the pan passes the magnet test, is correctly sized, and centered, but the cooktop still won’t engage, the pan-detection sensor in that burner may have failed. The sensor sits inside the burner module and isn’t a user-replaceable part.
3. Error Codes on Induction Cooktops
Most induction cooktops display error codes when something goes wrong. Exact codes vary by brand, but categories are similar.
- E1, E2, or E0 codes typically point to a temperature sensor fault or overheating shutdown — turn the cooktop off, let it cool thirty minutes, try again.
- F-series codes (F0, F2, F47) usually mean communication errors between the control board and burner modules. On KitchenAid, F47 often relates to power supply or board communication.
- Codes that appear after a power outage frequently clear with a full breaker reset. If they don’t, the surge may have damaged the board.
4. Cooling Fan Running Constantly or Not at All
Induction cooktops have internal cooling fans for the electronic modules. After heavy use, the fan runs ten to fifteen minutes after the burners are off — that’s normal. What isn’t: a fan that never stops, one that runs loudly when the cooktop is idle, or one that’s silent during cooking. A fan stuck on usually means a sensor is feeding bad data to the control board. A silent fan during cooking usually means the fan motor has failed — and running the cooktop without ventilation will eventually damage the electronics.
If the fan is silent, stop using the cooktop until it’s repaired.
5. Whole Cooktop Is Dead After a Power Event
Power surges from storms, lightning, or utility events are one of the most common reasons induction cooktops fail. The electronics inside — control board, IGBT power modules, capacitors — don’t tolerate surges the way simpler appliances do. The cooktop may show no display, freeze on the screen, or beep without responding. Try a full breaker reset first — off completely, wait sixty seconds, back on. If that doesn’t restore it, the control board or one of the power modules likely took the hit. A professional appliance repair company can identify which component failed and replace just that module rather than the whole unit.
DIY-Friendly vs. Tech-Required
Pan compatibility checks, breaker resets, control-lock toggling, and panel cleaning are reasonable DIY steps.
Anything past those — coil replacement, power module diagnosis, control board work, fan motor replacement — belongs to a technician. Induction power modules can hold residual electrical charge in capacitors after power is removed, and the diagnostic tools are brand-specific. A wrong part guess on an induction unit isn’t cheap.
How a Service Call Plays Out
When our Jacksonville appliance repair technicians handle an induction cooktop call, diagnosis follows a clear order:
- Confirm power to the unit.
- Read out stored error codes.
- Test the affected coil for continuity.
- Check the pan-detection sensor.
- Verify the temperature sensor.
- Inspect the cooling fan.
- Examine the IGBT power modules and control board.
We work on every major brand — Bosch, Miele, Thermador, KitchenAid, Wolf, Samsung, GE Profile, GE Café, Frigidaire, Electrolux, Whirlpool, Jenn-Air.

Conclusion
Induction cooktops are reliable when the right pan sits on the right zone and the electronics are working as designed. When something fails, the cause is almost always pan compatibility, a power issue, or a single component — not the whole unit. Run through the troubleshooting steps above. When the issue is inside the cabinet, Appliance Repair Jax handles induction cooktop repair across Jacksonville for every major brand.
