Answer to continue safely
Is it safe to keep using?
Yes. The unit is cooling, but items inside may freeze. Raise the temperature set point before adding new items and remove anything that has frozen and thawed, as food quality may be compromised.
Can I reset the code?
Yes. The LO code clears automatically once the interior warms to within the normal operating range. Adjust the temperature setting and allow 2–3 hours for recovery.
When to stop immediately?
Stop if you notice: Perishables inside have fully frozen and thawed — assess food safety before consuming., The LO code returns within hours of raising the temperature setting to a warmer position..
Symptoms You May Notice
Fresh food compartment freezing items
Fruits, vegetables, and dairy products stored in the fresh food section are freezing solid.
Ice forming on stored items
A thin layer of ice crystals coats food packaging that should remain unfrozen under normal operating conditions.
Crisper contents frozen solid
Produce in the crisper drawers is frozen rather than chilled, making it unusable.
Thermostat reading appears inaccurate
The displayed temperature setting looks normal but the actual compartment temperature is several degrees colder.
Possible Causes
Temperature control set too low
The most common cause on compact fridge models. If the thermostat is turned to its coldest setting, the unit will cool below the safe refrigeration range.
Requires ProfessionalLow ambient room temperature
Whirlpool compact fridges installed in cold garages or unheated spaces may over-cool when room temperature drops below the minimum operating threshold (typically 60 °F / 16 °C).
Requires ProfessionalDefective thermistor or temperature sensor
A faulty thermistor sends false low-temperature readings to the control board, causing the compressor to run continuously. Requires professional testing and part replacement.
Requires ProfessionalSafe Checks You Can Do
-
1
Raise the temperature set point
Use the control panel to increase the set temperature to 37–38 °F (3 °C). Allow the unit to stabilize for 2–3 hours and check whether the LO code clears.
On dial-controlled compact models, the mid-range position usually corresponds to the recommended 37 °F setting.

2
Verify ambient installation temperature
Check the room temperature where the fridge is installed. If it is below 60 °F (16 °C), move the unit to a warmer location or provide supplemental heating in the space.
Whirlpool's compact fridge operating range for WUR and WHR series is 60–90 °F ambient. Cold garages in winter fall outside this range.
Tools required
When to Call a Professional
Contact a qualified technician if:
- LO code persists even after raising the set temperature to the warmest available setting.
- A thermometer placed inside confirms freezing temperatures despite a warm set point, indicating a sensor or board fault.
