Answer to continue safely
Is it safe to keep using?
No. HI means the column refrigerator is not maintaining safe temperatures. Verify food safety and move perishables until the cause is identified and resolved.
Can I reset the code?
Yes. Press any panel button to silence the HI alarm. The alert clears automatically once the cabinet returns to a safe range — but the root cause must still be addressed.
When to stop immediately?
Stop if you notice: Stop if HI persists more than 3 hours with the door confirmed closed and no recent loading., Stop if the compressor is running and cabinet temperature continues to rise..
Symptoms You May Notice
Column cabinet noticeably warmer than set point
Beverages, produce, and dairy products inside the DRR24 or DRR30 feel warmer than usual, indicating the column cabinet temperature has risen above the alarm threshold.
HI alarm on the column refrigerator panel
The DRR24/DRR30 display flashes HI and sounds an audible alarm, prompting the user to investigate.
Visible gap in door seal or door left ajar
Warm ambient air from the surrounding cabinetry is entering the column cabinet due to a seal failure or door left slightly open.
Compressor running but cabinet not reaching set point
The compressor operates continuously but the column cabinet temperature remains above the set value, suggesting a cooling system or airflow issue.
Possible Causes
Column refrigerator door ajar or gasket failure
The DRR24/DRR30 column refrigerator door was left open or the door gasket has failed, allowing warm air to continuously enter the tightly-integrated cabinet.
DIY PossibleWarm item loading spike
A large quantity of warm items was recently loaded, temporarily pushing the column cabinet temperature above the alarm threshold.
DIY PossibleRefrigeration system fault
An underlying cooling fault — failed fan, defrost issue, or refrigerant loss — is preventing the DRR-series column from reaching its set temperature.
Requires ProfessionalSafe Checks You Can Do
-
1
Confirm door is fully closed and sealed
Inspect the column refrigerator door gasket by running your hand along its perimeter with the unit running. Cold air escaping indicates a seal failure. Verify the door handle alignment and that nothing inside blocks full closure.
Column refrigerators installed flush in cabinetry can develop gasket compression over time — check that the cabinet surround is not preventing full door travel.
-
2
Allow temperature recovery after loading
If HI appeared after loading groceries, allow 2–3 hours for the DRR24/DRR30 to recover to the set point. Minimize door openings during recovery.
Column refrigerators benefit from staged loading — adding items in batches rather than all at once reduces temperature spikes.

3
Check for concurrent E-series fault codes
Review the display history for E1, E3, or E4 codes that may be the underlying cause of HI. If any E-series code is present, diagnose those faults first before treating HI as a standalone issue.
HI on a column refrigerator is often a downstream effect of an E-series fault — always check for concurrent codes.
When to Call a Professional
Contact a qualified technician if:
- HI persists with no door, gasket, or loading explanation — sealed system or compressor fault suspected.
- Gasket or door alignment adjustment has not resolved HI — hinge adjustment required.
- HI accompanies compressor short-cycling — sealed system diagnosis required.
