Model compatibility: KitchenAid reuses codes across series and model years, so H may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The "H" indicator is not a fault — it is a residual-heat warning showing that a cooking zone is still hot enough to cause burns, even though it is switched off.
Signs
Symptoms you may notice
The zone is off but the display still shows a heat warning.
The indicator usually fades after the glass cools.
There may be no change in cooking performance once the zone is cool.
Why it happens
Possible causes
Normal residual heat stored in the glass and cookware area.
Recent high-power cooking.
No repair cause at all if the indicator clears normally as the surface cools.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Keep hands, towels and utensils away from a zone showing "H"
Wait for the indicator to clear before cleaning that zone
No reset is required — this is a normal safety indicator
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
Please avoid
What not to attempt
Do not open internal panels or access high-voltage components
Do not bypass door locks, safety switches or interlocks
Do not adjust, disconnect or repair any gas connection or valve

When to call a technician
If the safe checks do not resolve the condition, schedule an independent KitchenAid appliance diagnosis. Provide the full model number and a photo of the H display so the technician can start with the correct model-specific code map.

For the record covered by this page, H relates to residual-heat indicator — the cooking zone is still hot. Confirm the exact definition against the full model number before ordering parts or authorizing an internal repair.
You can correct an obvious external condition and use the normal owner-approved restart or acknowledgement procedure. If the same code returns, clearing the display again does not repair the cause.
Only if the condition is clearly a normal status/maintenance indication and the appliance is operating normally. Stop using it for smoke, burning odor, arcing, repeated breaker trips, uncontrolled heating, gas odor, active leakage near electrical parts, or a significant loss of refrigeration.
No. The code identifies a condition or diagnostic path. Model-specific testing should confirm the failed component before parts are ordered.
