Frigidaire oven error codes
Frigidaire dishwashers show codes such as i10 or i20, and ovens show an F and two digits, such as F10 or F30. Frigidaire refrigerators show system faults starting with SY, such as SY EF, and sensor faults as OP or SH. On models without a display, a code may be shown as a pattern of flashing lights instead.
