Induction Cooktop Not Detecting Pan

An induction zone flashes a pan symbol, beeps, or switches itself off even though a pot is sitting squarely on it.

What it
usually means.

An induction cooktop heats only when it senses a magnetic pan of a suitable size centered on the zone; otherwise it shows a pan symbol and cancels the zone after a short wait. Most of the time the pan is the answer: aluminum, copper, glass and some stainless steel will not work, and a base that is warped or too small may not register. When a known good pan on a zone that used to work still is not detected, the coil, its sensing circuit or the power board that drives it may have failed. A built-in induction cooktop also needs air from the cabinet below, and blocked vents let its electronics overheat and drop zones.

An induction cooktop lies upside down on a padded mat on a kitchen island in a US home, its bottom cover off to show copper coils and a green power board, while a technician's hand holds a meter probe to a terminal. The 6 causes, cheapest first

Answer these first

01

Does a magnet cling firmly to the bottom of the pan?
02

Does the pan cover most of the zone's marked circle?
03

Does the problem follow the pan, or stay with the zone?
04

Does the display show a code as well as the pan symbol?
05

Is the cabinet below packed tight, or a drawer pushed up against the cooktop's underside?

Check these
before you book.

Induction cooktop not detecting pan: 5 checks, and none of them costs anything.

01

Hold a magnet to the base of the pan; if it does not grip firmly, try a different pan.

02

Center a pan at least as wide as the zone's inner marking and try again.

03

Swap the pan onto another zone, and another pan onto this one, to see which one is at issue.

Also worth checking

  • Clear anything stored against the cooktop's underside and make sure its vent openings are free.
  • Write down any code that appears alongside the pan symbol.

How soon does it need a visit?

A zone that will not detect a pan is not an emergency. Cook on another zone and book a visit. If it comes with a burning smell, a breaker trip, or a zone that heats when it should be off, switch off the breaker.

6 things induction cooktop not detecting pan turns out to be, from pan not magnetic or too small to power board no longer driving the zone.

The cost guide
  1. 01 no repair

    Pan not magnetic or too small

    If a magnet does not grip the base firmly, or the base is smaller than the zone's minimum, the cooktop will not heat. A suitable pan solves it.

    No repair: check it yourself
  2. 02 no repair

    Warped or ridged pan base

    A base that rocks, or has a raised ring, does not sit close enough to the glass for the coil to sense it.

    No repair: check it yourself
  3. 03 no repair

    Lock setting or a timer ending the zone

    A control lock, or a zone timer that has run out, can look like a missed pan. The manual shows how to clear each one.

    No repair: check it yourself
  4. 04 low

    Overheat shutdown from blocked airflow

    The cooling fan draws air through the space under the counter. A stalled fan or a blocked inlet lets the electronics overheat, and zones drop out.

    Fixed by cooling fan and downdraft repair See cooktop fan runs constantly
  5. 05 moderate

    Coil or pan sensor failing

    Each zone has a coil and a sensing circuit. A coil with a broken winding, or a failed sensor, leaves that zone blind to every pan.

    Fixed by induction board and coil repair On an induction cooktop
  6. 06 moderate to highest

    Power board no longer driving the zone

    One power stage often drives a pair of zones. If both zones on one side quit together, the board is the likely cause.

Questions about
induction cooktop not detecting pan.

Why does my stainless pan work on one zone but not another?
Some stainless pans are only weakly magnetic, and larger zones need more pan to sense. A pan that just passes on a small zone can fail on a large one.
Can I use a converter disk for pans that are not magnetic?
A converter disk works but heats slowly and gets very hot itself. Read what your cooktop's manual says before using one.
Why does the zone switch itself off after a minute?
Without a pan it can sense, the cooktop cancels the zone for safety. If a pan is there and it still cancels, the coil or the board needs testing.
Could the cabinet under the cooktop affect pan detection?
Indirectly. Blocked airflow lets the electronics overheat, and they shut zones down to protect themselves. Keep the clearance the installation guide asks for.
