1. Introduction
The Deye KB-5150 is a precision temperature and humidity sensor designed as a replacement part for various Deye and Midea dehumidifier models. This sensor plays a critical role in the accurate measurement of ambient temperature and humidity, enabling your dehumidifier to operate efficiently and maintain desired environmental conditions. It is specifically intended to resolve issues indicated by an "L3" error code on compatible dehumidifiers, suggesting a malfunction in the original sensor.

- W20A3
- MD-35E
Always verify the model number of your dehumidifier before purchasing to ensure compatibility.
4. Installation Instructions
Safety First: Always disconnect the dehumidifier from the power supply before attempting any installation or repair.
- Power Off: Ensure the dehumidifier is completely unplugged from the electrical outlet.
- Access Panel: Locate and carefully remove the access panel(s) on your dehumidifier that provide access to the internal components, specifically where the existing temperature/humidity sensor is located. This may require a screwdriver.
- Locate Old Sensor: Identify the old temperature and humidity sensor. It typically looks similar to the replacement part and will be connected via a small wire harness (often labeled CN2 on the sensor board).
- Disconnect Old Sensor: Gently disconnect the wire harness from the old sensor. Note its orientation if it's not keyed.
- Remove Old Sensor: Carefully remove the old sensor from its mounting location. It might be clipped in or secured with a small screw.
- Install New Sensor: Position the new Deye KB-5150 sensor in the same location as the old one. Ensure it is securely mounted.
- Connect New Sensor: Connect the wire harness to the new sensor's connector (CN2). Ensure a firm connection.
- Reassemble: Replace any removed access panels and secure them.
- Test: Plug the dehumidifier back into the power supply and turn it on. Monitor for proper operation and check if any error codes, such as "L3", have been resolved.
If you are unsure about any step, it is recommended to consult a qualified technician or refer to your dehumidifier's specific service manual.
5. Operation
The Deye KB-5150 sensor operates automatically once installed correctly within a compatible dehumidifier. Its function is to continuously monitor the ambient temperature and relative humidity. This data is then transmitted to the dehumidifier's control board, which uses this information to regulate its operation (e.g., compressor cycling, fan speed) to achieve and maintain the user-set humidity levels. No direct user interaction with the sensor itself is required after installation.
6. Maintenance
The Deye KB-5150 sensor is designed to be maintenance-free under normal operating conditions. However, to ensure its longevity and accurate performance:
- Keep Clean: Periodically, when performing general dehumidifier maintenance (e.g., cleaning air filters), you may gently wipe the exterior of the sensor with a soft, dry cloth to remove any dust accumulation. Avoid using liquids or abrasive cleaners.
- Avoid Obstruction: Ensure that the sensor's location within the dehumidifier is not obstructed by debris, dust, or other components, as this can affect its ability to accurately read temperature and humidity.
- Handle with Care: When handling the sensor during installation or inspection, avoid touching the sensitive sensing elements directly.
7. Troubleshooting
This sensor is primarily used to address specific error codes related to temperature and humidity sensing. The most common issue it resolves is the "L3" error code on compatible Deye and Midea dehumidifiers.
7.1 "L3" Error Code
If your dehumidifier displays an "L3" error code, it typically indicates a problem with the temperature or humidity sensor. Replacing the faulty sensor with the Deye KB-5150 is the recommended solution.
- Symptom: Dehumidifier displays "L3" error, unit may not operate or operates erratically.
- Cause: Malfunctioning or disconnected temperature/humidity sensor.
- Solution:
- Ensure the dehumidifier is unplugged.
- Verify the Deye KB-5150 sensor is correctly installed and its connector (CN2) is firmly seated.
- If the error persists after verifying installation, the original sensor was likely faulty, and the new sensor should resolve the issue.
- If the "L3" error still appears after replacing the sensor and verifying connections, there might be a more complex issue with the dehumidifier's control board or wiring, requiring professional diagnosis.
7.2 General Troubleshooting Tips
- No Power: Ensure the dehumidifier is properly plugged into a functional power outlet.
- Incorrect Readings: If the dehumidifier displays incorrect temperature or humidity readings after sensor replacement, double-check the sensor connection.
8. User Tips
- Static Electricity: When handling electronic components like this sensor, it's good practice to discharge any static electricity from your body by touching a grounded metal object before installation.
- Gentle Handling: The sensor is a delicate electronic component. Handle it gently to avoid damage to the pins or the sensing element.
- Documentation: Keep this manual and any service diagrams for your dehumidifier handy for future reference.
