ERC FAILURE CODES
The oven may stop operating but not give an F code on the display immediately.
F codes are stored in nonvolatile EEPROM memory until the same fault occurs
twice consecutively. F codes can be recalled by pressing together TIMER, CLOCK
and 9. While F codes are displayed, pressing 8 and 6 together will clear them. A
fault must exist continuously for 5 minutes before an F code is recorded (F2 and
F8 are sooner).

unlocked,
both lock
switches
will be in
the open
position.

consists of a lock motor cam and switch assembly, lock hook and mounting
plate.
