The **E-61** display on a Samsung microwave points to **open humidity sensor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **E-61**. Search normalization stores it as **E61** while preserving the characters a homeowner actually sees.

Quick answer
Open humidity sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so E61 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-61** display on a Samsung microwave points to **open humidity sensor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **E-61**. Search normalization stores it as **E61** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
E-61 can be accompanied by this pattern: the control is not receiving an expected sensor signal or the signal is outside its accepted range.
When the E-61 condition is present, the appliance may stop a feature, limit operation, or repeat the code during the same stage.
The E-61 display becomes more meaningful if the affected function can behave intermittently if the signal or connection is unstable.
The E-61 display becomes more meaningful if e-61 appears and the microwave may stop or limit the function associated with open humidity 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.
For E-61, start by doing this: photograph the code and note the exact operating stage when it appears.
A safe owner-level check is to check only user-accessible conditions that can physically affect the monitored function.
The next non-invasive check is to avoid replacing a sensor solely from the display; wiring, connectors, supply conditions, and the control can create the same result.
The next non-invasive check is to record the exact code and model number.
As an external check for E-61, power the microwave off for 60 seconds only if Samsung's model guidance allows a reset.
Before opening any service area, do not remove the outer cabinet or access internal high-voltage components.
Important safety warning. When working around a microwave that shows E-61, keep the checks external and non-invasive. Do not remove the microwave outer cabinet. High-voltage components can retain dangerous energy even after the appliance is unplugged.
Get help
When to request repair service
If the code returns, model-specific sensor, harness, connector, and control-board testing is appropriate. If E-61 keeps returning, record the stage at which it reappears so the technician can test the open humidity sensor error path instead of replacing parts by guesswork.

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 **E-61** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **E-61**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
No. **E-61** 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 **Microwave E-61** separate from same-looking codes used by other Samsung appliance families.
