The oven may stop operating but not give an F-code on the display immediately. Generally, a fault must exist continuously for 5 minutes before an F code is recorded (F2 is sooner). F-codes are stored in non-volatile EEPROM memory until the same fault occurs twice consecutively. After that, the F-code will be displayed. F-codes can be recalled by pressing together TIMER, CLOCK, and 9.
Multiple fault codes may be displayed. The latest fault code will appear on the right of the display. While F-codes are displayed, pressing 8 and 6 simultaneously will clear the codes from the memory. Clear the fault code after the failure has been corrected.
