Error Code HUMIDITY_SENSOR
Humidity sensor disconnection or failure prevents humidity monitoring
Moderate
Address soon - your appliance may not work properly
Also displayed as: Humidity Sensor Error
What This Means
Bad connector contact at CN60 pin 7 and CN90 pin 8; Open circuit in sensor wiring; Short circuit in humidity sensor; Water infiltration or condensation in sensor; Sensor age or calibration drift
What actually causes this:
The humidity sensor lost electrical connection or the sensor element failed, preventing measurement of compartment humidity
First Thing to Check
Make sure CN60 connector is fully seated and look for moisture around the sensor
Parts Involved
How to Fix
- 1
Check CN60 connector insertion at MAIN PCB
- 2
Measure voltage between CN60 pin 7 (W/YEL) and CN90 pin 8 (FLAT_WHT)
- 3
Measure resistance between same pins (should be about 50 ohms when open)
- 4
Compare to humidity table DATA2
- 5
Check for water damage or condensation
