Samsung Microwave E-25 Error — What It Means
Samsung defines E-25 as a Micro Cook Abnormal Temperature Error. The control board has detected an unusual temperature condition during microwave operation. Samsung does not publish the exact internal trigger logic for this code, but it falls under the temperature-related fault group in their support tables.
The manufacturer’s published remedy is straightforward: power-cycle the microwave and contact service if the error persists. This is not a generic component failure message but rather a temperature-monitoring alert during cooking.
Common Causes
- Temperature sensor or thermistor circuit fault The microwave’s temperature-sensing circuit may be reading incorrectly or has failed, though Samsung does not publish a detailed root-cause list for E-25.
- Control board input path fault The main control board (MICOM) may not be receiving correct temperature signals due to internal circuitry or connector issues.
- Moisture or wet control area Samsung commonly flags moisture intrusion around control panels as a contributor to microwave faults.
- Overheating or blocked ventilation Abnormal internal heat buildup from blocked vents or ambient conditions can trigger temperature-related codes.
Step-by-Step Fix
- Verify the code on the display and confirm your model number against Samsung’s information-code support table.
- Unplug the microwave or switch off the breaker and leave it powered down for a full 60 seconds.
- Restore power and check whether the E-25 code has cleared from the display.
- Check for moisture around the control panel or interior and allow the unit to dry completely if any dampness is present.
- Test the microwave with a short cook cycle to see if the fault reappears.
- If the code returns, stop using the microwave and proceed to component-level diagnosis or contact Samsung service.
- Consult a service technician for sensor circuit testing, harness inspection, and control board diagnosis, as Samsung does not provide public field-service specs for E-25.
Parts Often Needed
| Part | Notes |
|---|---|
| Temperature sensor / thermistor | Amazon | Check model-specific part number if diagnostics point to sensor circuit failure. |
| Main control board (MICOM) | Amazon | Replace if power-cycle and external checks rule out sensor and wiring faults. |
When to Call a Pro
Call a Samsung-authorized service technician if the E-25 code returns after a full power reset. Samsung’s published guidance directs users to the Service Centre when this error persists, and the manufacturer does not provide voltage, resistance, or diagnostic decision trees for E-25 in public support materials. A qualified technician will have access to service manuals, model-specific sensor specifications, and control-board testing procedures needed for safe component-level repair on microwave high-voltage systems.
