Moderate
Address soon - your appliance may not work properly
Also displayed as: F19
How to Fix
- 1
Unplug the unit.
- 2
Check if any connector is disconnected or loose: check all electrical wiring of Main PCB and igniter wiring.
- 3
If connector is loose, reconnect and retest.
- 4
Check resistance of convection bake igniter: Normal = 45–400 Ω at room temperature. If infinite (open), replace the failed convection bake igniter.
- 5
Check lower thermistor resistance: Normal approximately 1.09 kΩ at 77°F (25°C). Check at CN60 pins 4 and 5, and CN61 pins 5 and 6 of Main PCB. If abnormal, replace the oven temperature sensor.
- 6
Plug in unit and verify thermistor in test mode. Display should show current oven temp between 70°F and 90°F at room temperature.
- 7
Confirm the oven gas shut-off valve behind the range is fully open.
- 8
If igniters and sensor are normal but F19 persists, replace the Main PCB.
