The humidity sensor is not working correctly
Minor
Usually easy to fix - may resolve on its own
Also displayed as: Both F and R LEDs blink
What This Means
Disconnected or poorly seated connector at MAIN PCB CN34; Failed humidity sensor element; Solder defect at R349 on PCB; Failed MICOM IC01 pin 8
What actually causes this:
The humidity sensor (used for moisture management) has failed or its wiring is loose.
First Thing to Check
Reseat connector CN34 on the main board.
Parts Involved
How to Fix
- 1
Check MAIN PCB connector CN34 is fully seated
- 2
Measure voltage between CN34-4 and CN34-6; normal range 1.0V~3.5V
- 3
Open resistance of humidity sensor channel is approximately 50Ω
- 4
Check MICOM IC01 pin 8 voltage matches CN34-4/6
- 5
Check solder at R349
- 6
Replace sensor if reading out of range; replace PCB if PCB fault found
