Answer to continue safely
Is it safe to keep using?
No. HI on a freezer means food safety is at risk. Transfer frozen items to another freezer immediately and do not consume food that has reached above -9°C (15°F) for more than 2 hours.
Can I reset the code?
Yes. Press any panel button to silence the alarm. HI will clear automatically once the cabinet temperature returns to a safe range — this only indicates the symptom is resolved, not the root cause.
When to stop immediately?
Stop if you notice: Stop if HI persists more than 4 hours with doors sealed and no recent loading., Stop if the compressor is running but the cabinet temperature continues to rise..
Symptoms You May Notice
Frozen food softening or partially thawing
Items in the column freezer cabinet feel soft or show surface thawing, indicating the cabinet temperature has risen above -9°C (15°F).
HI flashing on the display with alarm
The DRZ24/DRZ30 control panel flashes HI and sounds a continuous alarm until acknowledged or until temperature recovers.
Door ajar or seal failure
Warm ambient air is entering the cabinet because the door was left open, or a damaged gasket is allowing continuous infiltration.
Compressor running but not achieving target
The compressor is operating but the cabinet temperature remains above the set point, suggesting an airflow or refrigeration system issue.
Possible Causes
Door left open or gasket failure
The column freezer door was left ajar or the gasket is torn, compressed, or misaligned, allowing warm air to enter continuously.
DIY PossibleHeavy loading of warm items
A large amount of warm or room-temperature food was loaded at once, temporarily pushing cabinet temperature above the alarm threshold.
DIY PossibleRefrigeration system fault
An underlying fault — failed fan, defrost issue, or refrigerant loss — is preventing the freezer from reaching its set temperature.
Requires ProfessionalSafe Checks You Can Do
-
1
Check door closure and gasket condition
Close the freezer door firmly and inspect the gasket by running your hand around its perimeter while the unit is running. Cold air escaping indicates a seal failure. A dollar-bill test (resistance when pulled from closed door) confirms seal quality.
Clean gaskets with warm soapy water to remove residue that can prevent proper sealing. Dacor column freezer gaskets can be replaced with OEM parts.
-
2
Allow recovery after loading
If HI appeared after loading groceries or recently-purchased frozen items, allow 2–4 hours for the cabinet to recover. Minimize door openings during this period.
Dacor recommends pre-chilling or pre-freezing items before loading into a premium column freezer to avoid temperature spikes.

3
Verify no active F-series fault codes
Check the display for any F-series codes (F1, F3, F4) that may be the underlying cause of HI. If present, diagnose and resolve those faults first.
HI is often a consequence of another fault rather than a standalone issue — always check for concurrent codes.
When to Call a Professional
Contact a qualified technician if:
- HI persists with no apparent door, loading, or gasket issue — refrigerant loss or compressor failure suspected.
- Gasket replacement has not resolved HI — door alignment or hinge adjustment needed.
- HI accompanies short-cycling of the compressor — sealed system diagnosis required.
