Error Code F2
Upper oven sensor short — oven thermistor is shorted
Moderate
Address soon - your appliance may not work properly
Also displayed as: F2
How to Fix
- 1
Unplug the unit.
- 2
Check sensor connector for looseness or disconnection at CN60 pins 4 and 5 of Main PCB.
- 3
Measure thermistor resistance across sensor leads — normal is approximately 1.09 kΩ at 75°F (25°C). A short will read below 5 Ω.
- 4
If resistance is shorted (below 5 Ω), replace the upper oven temperature sensor.
- 5
If resistance is normal, enter test mode and verify thermistor reading is between 70°F and 90°F at room temperature.
- 6
If test mode value is still abnormal, replace the Main PCB.
- 7
Reconnect all wiring and test oven for normal operation.
