Minor
Usually easy to fix - may resolve on its own
Also displayed as: F-1-1 (LED blink pattern on panel)
What This Means
Connector at CN31 loose or disconnected; Sensor reading above 149°F (65°C) or below -58°F (-50°C); Sensor wire open or shorted; Failed sensor unit
What actually causes this:
The sensor connector worked loose at the top hinge area, or the sensor was damaged during door removal.
First Thing to Check
Check that the ambient sensor connector at CN31 on the main board is firmly seated — it can loosen when the refrigerator doors are serviced.
Parts Involved
How to Fix
- 1
Check MAIN PCB connector CN31 is fully seated
- 2
Measure resistance between CN31 #1 (Yellow) and CN31 #4 (Yellow) — compare to DATA1 temperature table
- 3
Measure voltage at CN31 #1 (Yellow) vs REG1 HEAT SINK ground — should be 0.6V to 4.6V
- 4
Check IC01 MICOM pin #72 input voltage
- 5
Note: ambient sensor is located in the upper right Top Table area near the upper hinge
