Frigidaire air conditioner 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. Frigidaire window and portable air conditioners show two-letter codes such as AS or ES for a failed sensor, F1 or F2 for freeze protection, and P1 when a portable's water tray is full. On models without a display, a code may be shown as a pattern of flashing lights instead.
