Induction Cooktop Doesn't Recognize Pan

On a range, the symptom of "induction cooktop doesn't recognize pan" is one of the most frequently reported homeowner complaints — and it almost always traces back to a small set of root causes that you can investigate in under fifteen minutes without specialized tools. The induction surface beeps and shuts off after a few seconds, even with cookware on the burner. Before opening any access panel, unplug the appliance (or shut off the gas where applicable), give it a few minutes for residual current to bleed off, and have a flashlight, a phone camera for documenting cable routing, and a small bowl handy for any water that may release when you disconnect a hose.

Most service technicians work through the same checklist for this complaint, and the order matters because each successive cause requires more disassembly. 1. The cookware is not ferromagnetic — only steel and cast iron will work. 2. The cookware diameter is too small for the burner zone. 3. The cookware bottom is warped and not in flat contact with the surface. 4. The induction coil under that burner has a marginal connection. Walk these in order and stop as soon as one of them resolves the symptom — there is no need to keep digging deeper if an early-list fix restores normal operation.

Practical do-it-yourself steps you can attempt safely: Step 1: Hold a magnet to the bottom of the pan — it must stick firmly. Step 2: Use cookware that matches or exceeds the burner zone diameter. Step 3: Check the pan bottom on a flat surface; replace if it rocks visibly. After completing the steps, run a short empty cycle to confirm the symptom is gone before reloading the appliance with laundry, dishes, or food. Document anything you replaced — if the same fault returns within a few weeks, the technician will want to know what has already been ruled out.

When to escalate to a service technician: If multiple known-good pans are not recognized on a single zone, that zone's coil or its associated power module needs service. If the unit is still under the manufacturer's parts-and-labor warranty, do not perform any repair that involves opening a sealed system, breaking a tamper sticker, or substituting a non-OEM part — any of those can void coverage. Keep the model number printed on the rating plate and the date of purchase ready when you call; a competent technician can usually narrow the diagnosis over the phone if you describe what you have already tried.
