For the Samsung Refrigerator families covered by the source set, **91E** means **refrigerator compressor low-voltage error (dual-compressor models)**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **91E**. Search normalization stores it as **91E** while preserving the characters a homeowner actually sees.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 91E may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Signs
Symptoms you may notice
A symptom that fits 91E is that cooling or heat-pump performance can drop or stop.
While 91E is active, the compressor can attempt to start, stop unexpectedly, or run without the expected result.
While 91E is active, the code can follow abnormal voltage, current, inverter, or motor feedback.
The 91E display becomes more meaningful if 91E appears and the refrigerator can show behavior related to refrigerator compressor low-voltage error (dual-compressor models).
91E can be accompanied by this pattern: cooling, airflow, ice-making, defrost, or temperature performance may become intermittent depending on the affected subsystem.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before requesting service for 91E, confirm household power is stable and the appliance has not just experienced an outage or surge.
As an external check for 91E, verify only external airflow and temperature conditions described in the manual.
As an external check for 91E, do not open sealed refrigeration circuits or inverter/high-voltage sections.
The next non-invasive check is to photograph the code before resetting or unplugging the refrigerator.
For 91E, start by doing this: verify doors, visible airflow/ice obstructions, water/ice-bin seating, or demo mode only when relevant.
For 91E, start by doing this: use the exact model manual because Samsung refrigerator codes vary by family.
Important safety warning. Safety takes priority over clearing 91E. Protect food if temperatures are no longer safe. Do not open the sealed refrigeration system or energized inverter/compressor circuits.

When to request repair service
For 91E, the service threshold is straightforward: Compressor/inverter issues require qualified electrical and refrigeration-system diagnosis, especially when temperatures are unsafe or the code returns after a power reset. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Resetting can clear a temporary state, not a persistent issue. If **91E** comes back, preserve the code and move to the safe checks or model-specific service path.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **91E** before replacing anything.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Refrigerator 91E** separate from same-looking codes used by other Samsung appliance families.
