What This Means
Ice room thermistor disconnected; Wire harness damaged from ice storage area to Main PBA; Thermistor defective (open circuit or short); Main PBA defect

The ice room sensor wire came loose or sensor failed
First Thing to Check
Check if ice bucket empties normally — malfunction may indicate sensor/heater issue
Parts Involved
How to Fix
- 1
1. Measure voltage at MAIN PCB CN90 between pins 2 and 4 — must be 4.5V to 1.0V
- 2
2. Check connector at ice room sensor location
- 3
3. Disconnect CN90 and measure thermistor resistance (power off)
- 4
4. At 77°F (25°C), should read 5.0 kΩ
- 5
5. If resistance is normal, replace Main PBA
