Answer to continue safely
Is it safe to keep using?
Yes. TEMP-HI is a warning, not a unit failure. Wine stored above optimal temperature for short periods (a few hours) is rarely ruined. However, address the cause promptly to protect your wine collection.
Can I reset the code?
Yes. Press any panel button to acknowledge the alarm. TEMP-HI will clear automatically once the cabinet returns to within the acceptable temperature range.
When to stop immediately?
Stop if you notice: Stop if TEMP-HI persists more than 4 hours after correcting door, ambient, and ventilation issues., Stop if the compressor runs continuously without the cabinet temperature dropping..
Symptoms You May Notice
Wine cabinet warmer than set temperature
Bottles in the wine refrigerator feel noticeably warmer than usual, and the cabinet temperature display reads above the set point.
TEMP-HI on the wine refrigerator display
The HWC242 or Heritage/Modernist wine column displays TEMP-HI with an audible alarm indicating the cabinet has exceeded its high-temperature threshold.
Compressor running continuously
The wine refrigerator compressor operates without pause, attempting to cool the cabinet to the set point but failing to reach it.
Warm air detectable around door seal
Warm air can be felt around the door perimeter, indicating the gasket has failed or the door is not fully closed.
Possible Causes
Door left open or gasket failure
The wine refrigerator door was left ajar or the door gasket has deteriorated, allowing warm ambient air to continuously enter the cabinet.
DIY PossibleHigh ambient room temperature
The room temperature around the wine refrigerator has risen significantly, overwhelming the unit's cooling capacity — common in summer or non-climate-controlled spaces.
DIY PossibleRefrigeration system fault
A compressor, fan, or refrigerant issue is preventing the wine cabinet from maintaining its set temperature.
Requires ProfessionalSafe Checks You Can Do
-
1
Check door seal and ambient temperature
Close the wine refrigerator door firmly and inspect the gasket by running your hand around the seal with the unit running. Also check the room temperature — Dacor wine units are rated for ambient temperatures of 60–90°F (15–32°C).
In summer months, temporarily raising the wine storage set point by 2–3°F can reduce TEMP-HI occurrences in warmer rooms.
-
2
Ensure adequate ventilation clearance
Verify the wine refrigerator has the minimum clearance required around condenser vents — typically 1–2 inches on sides and back, or per the model's installation guide. Blocked vents cause heat build-up and TEMP-HI.
Built-in wine columns (Modernist series) vent from the front grill — ensure the grill is not blocked by cabinetry or decorative panels.

3
Clean condenser coils
Unplug the wine refrigerator and vacuum the condenser coils (typically accessible behind the bottom front grille). Dust and lint accumulation significantly reduces cooling capacity.
Dacor recommends cleaning condenser coils every 6–12 months. A clogged condenser is a very common cause of TEMP-HI on wine refrigerators.
When to Call a Professional
Contact a qualified technician if:
- TEMP-HI persists with correct ambient conditions and clean coils — sealed system diagnosis needed.
- Compressor runs but wine cabinet temperature does not drop — possible refrigerant loss.
- Fan in condenser area is not operating — condenser fan motor replacement required.
