The **E-41** display on a Samsung microwave points to **open easy/ph sensor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **E-41**. Search normalization stores it as **E41** while preserving the characters a homeowner actually sees.

Quick answer
Open Easy/PH sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E41 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **E-41** display on a Samsung microwave points to **open easy/ph sensor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **E-41**. Search normalization stores it as **E41** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
When the E-41 condition is present, the control is not receiving an expected sensor signal or the signal is outside its accepted range.
On affected Samsung microwave models, the appliance can stop a feature, limit operation, or repeat the code during the same stage.
On affected Samsung microwave models, the affected function can behave intermittently if the signal or connection is unstable.
On affected Samsung microwave models, e-41 appears and the microwave may stop or limit the function associated with open easy/ph sensor error.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
A safe owner-level check is to photograph the code and note the exact operating stage when it appears.
With E-41 recorded, check only user-accessible conditions that can physically affect the monitored function.
With E-41 recorded, avoid replacing a sensor solely from the display; wiring, connectors, supply conditions, and the control can create the same result.
With E-41 recorded, record the exact code and model number.
Before opening any service area, power the microwave off for 60 seconds only if Samsung's model guidance allows a reset.
As an external check for E-41, do not remove the outer cabinet or access internal high-voltage components.
Important safety warning. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged. If resolving E-41 would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
If the code returns, model-specific sensor, harness, connector, and control-board testing is appropriate. In a service visit for E-41, model-specific testing should follow the open easy/ph sensor error circuit rather than treating the code as proof of one failed part.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
You can try the one reset Samsung documents for the model, but **E-41** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Do not keep operating the appliance through a hazardous symptom just to see whether **E-41** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
The code alone is not enough to justify a part. **E-41** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
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 **Microwave E-41** separate from same-looking codes used by other Samsung appliance families.
