Plain language
What this code means
High temperature alarm (Hi) — the refrigerator compartment exceeded the allowed high-temperature limit.
Signs
Symptoms you may notice
The cabinet may be warmer or colder than expected.
An alarm or flashing display can appear even when no individual component code is shown.
Recent door opening, loading, power interruption, or cooling-system trouble can influence temperature.
Why it happens
Possible causes
A door left open or frequent door opening.
Recent loading of warm food or a power interruption.
A refrigeration, airflow, sensor, or control problem if temperature does not recover.
Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

Do not bypass door locks, safety switches or interlocks

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 Hi display so the technician can start with the correct model-specific code map.

For the record covered by this page, Hi relates to high-temperature alarm. 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.
