Error Code F2

Upper oven sensor shorted

Also displayed as: F2

How to Fix

1. 1

   Unplug the unit.

2. 2

   Check if any connector is disconnected or loose: inspect sensor connection at CN60 (pins 4 and 5) and CN61 (pins 5 and 6) of Main PCB.

3. 3

   If connector is loose, reconnect and retest.

4. 4

   Measure thermistor resistance. Normal: approximately 1.09 kΩ ±10% at 77°F (25°C). Near-zero resistance = shorted sensor.

5. 5

   If thermistor resistance is abnormal (shorted), replace the upper oven temperature sensor.

6. 6

   Plug in unit and verify with test mode. Normal thermistor reading at room temperature should be 70°F to 90°F.

7. 7

   If sensor tests normal but F2 persists, replace the Main PCB.
