Induction Range Not Detecting Pan

An induction zone flashes, beeps, shows its no-pan symbol or switches itself off, even with a pan sitting right on it.

What it
usually means.

An induction range heats the pan itself: a coil under the glass makes a rapidly changing magnetic field, and only a pan with a magnetic base turns that field into heat. The range checks for a suitable pan before it powers a zone and keeps checking while you cook. If the base is not magnetic, too small for the zone, warped or off center, the zone refuses to start and shows its no-pan signal. When a pan that has worked for years is suddenly ignored, the trouble is on the range side: the coil, its sensor, the power board that drives it, or the cooling fan that protects the electronics.

Answer these first

01

Does a kitchen magnet stick firmly to the base of the pan?

02

Does the pan base cover the marked ring, and does it sit flat without rocking?

03

Is it one zone or every zone, and do other pans work on it?

04

Does the range show a code, and can you hear the cooling fan run?

05

Does the zone start and then cut out after a short while?

before you book.

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

01

Test the pan with a magnet; if it does not grip the base firmly, try a pan made for induction.

02

Center a flat pan that covers the marked ring and try the zone again.

03

Move a pan you trust to another zone to see whether the problem follows the pan or stays with the zone.

Also worth checking

  • Wipe the glass and the touch keys dry, and check that the controls are not locked.
  • Note any code and whether the cooling fan runs, and share both when you book.

How soon does it need a visit?

An induction zone that will not start is not an emergency. Keep cooking on the zones that work with suitable pans. If the glass is cracked, or the range smells of burning or trips the breaker, switch it off at the breaker and stop using it.

6 things induction range not detecting pan turns out to be, from pan not suited to induction to power board not driving the zone.

The cost guide
  1. 01 no repair

    Pan not suited to induction

    Aluminum, copper, glass and some stainless pans have no magnetic base, so the range cannot see them. A magnet that grips the base firmly is the quick test.

  2. 02 no repair

    Pan too small or warped

    A small pan on a large zone, or a base that rocks, may not be detected at all or may make the zone cut in and out.

  3. 03 no repair

    Control lock or water on the touch area

    A control lock, or spilled water pooling on the touch keys, can make the range ignore input or cancel a zone. Drying the glass and unlocking the controls brings it back.

  4. 04 low

    Electronics too hot to run

    A fan under the top cools the induction electronics. A fan that has stopped, or vents blocked by something stored against them, makes the range shut zones off to protect itself.

  5. 05 moderate

    Failed induction coil or its sensor

    Each zone has a coil and a temperature sensor under the glass. A damaged coil or sensor can stop the zone from recognizing any pan.

  6. 06 moderate to highest

    Power board not driving the zone

    The power board turns the household supply into the high-frequency current the coils need. When a section of it fails, one or two zones go dead and show the no-pan signal.

Questions about
induction range not detecting pan.

My pans say stainless steel. Why do they not work?
Not all stainless steel is magnetic. Pans made for induction usually have a magnetic layer in the base; if a magnet will not grip it, the range cannot heat it.
Why does the range hum or buzz with some pans?
A light hum or buzz on high settings is normal with induction, and pans with layered bases can make more of it. A loud rattle or a new grinding sound, especially from the fan, is worth a check.
Can I use a converter disk on my induction range?
A converter disk puts a magnetic plate under a pan that could not otherwise heat. It works, but it is slower, gets very hot, and your manual may say whether it is allowed. It also makes it harder to tell whether the range itself is working.
Is an induction repair usually worth it?
It depends on which part failed and on the age of the range. A sensor or a fan is modest work; a power board is a larger part, which is why we test before recommending anything.
