Seeing **25E** on a Samsung refrigerator narrows the problem to **refrigerator defrost heater error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **25E**. Search normalization stores it as **25E** while preserving the characters a homeowner actually sees.

Quick answer
Refrigerator defrost heater error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 25E 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
On affected Samsung refrigerator models, heating may be weak, absent, excessive, or stop unexpectedly.
Depending on the exact model, the appliance can pause when the control detects an unsafe or implausible temperature condition.
The 25E display becomes more meaningful if drying, washing, cooking, or defrost performance can change depending on the appliance.
On affected Samsung refrigerator models, 25E appears and the refrigerator can show behavior related to refrigerator defrost heater error.
25E can be accompanied by this pattern: cooling, airflow, ice-making, defrost, or temperature performance can become intermittent depending on the affected subsystem.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With 25E recorded, confirm the selected cycle or cooking mode is supposed to use heat.
Before opening any service area, check airflow, vents, filters, water supply, or door closure when those conditions affect temperature.
The next non-invasive check is to allow the appliance to cool before any owner-accessible inspection.
With 25E recorded, do not open energized high-voltage or heating sections.
For 25E, start by doing this: photograph the code before resetting or unplugging the refrigerator.
A safe owner-level check is to check doors, visible airflow/ice obstructions, water/ice-bin seating, or demo mode only when relevant.
Important safety warning. When working around a refrigerator that shows 25E, keep the checks external and non-invasive. 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
If the owner-accessible checks do not clear 25E, A returning heating/over-temperature code after external checks requires model-specific testing of sensors, heaters/ignition, relays, wiring, airflow, or control electronics. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **25E** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
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.
No. **25E** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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 25E** separate from same-looking codes used by other Samsung appliance families.
