What H means

On JennAir induction cooktops such as the JIC4536KS or JIC4536XS, an H on the display means the cooking zone is hot. The indicator lights even if the zone was never switched on, for example when heat has spread from the neighboring zone or when a hot pot was placed on it. When the zone cools, the H goes out. It is a safety indication and not an error.

Common causes of H

  • Residual heat from a recent pot
  • Heat spreading from the adjacent zone
  • Hot pot placed on an unused zone
✓ One safe check you can try

1. Do not touch the glass; leave it to cool. 2. Keep towels, plastic and pot holders off the zone. 3. Wait until the H disappears on its own. 4. If H stays on for a very long time after the cooktop has cooled, or shows with no heat source, switch the breaker off for a minute and call us.

! Why to stop there
  • It is a normal warning and not a defect.
  • An H that never goes out could point to a sensor issue.
  • The glass can burn skin while the H is lit.
  • We check the sensing only if H stays on when the surface is cool.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

HH questions
Is H an error code?

No. It simply means the cooking zone is hot. It is there to protect you from touching hot glass, and it goes out by itself.

Why does a zone I did not use show H?

Wait for the surface to cool and the H goes out by itself. It needs no button press or reset, and it is safe to ignore as long as you keep hands off the glass.

When should I worry?

If H stays lit after the cooktop has fully cooled for a long time, the sensing may need a check. We quote in writing and warrant our work for 30 days.
