Low Medium High

Code Meaning Severity Common Symptom

F1 Control board fault High The turntable spins and the interior light comes on, but food remains cold after a full cycle. The magnetron is not receiving power due to the control board fault. View F2 Temp sensor fault High Sensor-based cooking modes like reheat or defrost run for incorrect durations because the cavity thermistor sends wrong temperature data, resulting in cold centers or overheated edges. View F3 Door switch fault High Pressing start with the door firmly shut produces no response. The display may show the time counting but the magnetron and turntable do not activate. View F5 Humidity sensor fault Medium Selecting sensor-based programs like auto-reheat, auto-defrost, or popcorn results in F5 or the button has no effect. Manual timed cooking still works normally. View PF Power failure alert Low After a power interruption, the microwave clock resets and blinks, indicating the unit lost power during operation and needs the time re-entered. View SE Stuck key / keypad error Medium Pressing one button activates a different function — for example, pressing 5 enters 8, or pressing Start activates the clock set mode. View
