ASFrigidaire identifies AS as a room-temperature thermistor failure.
This source is for Frigidaire room air conditioners. If the display returns after the maker's model-specific guidance, contact Frigidaire; the code does not identify a repairable part.
ECFrigidaire identifies EC as a communications error.
This code description is from Frigidaire's room-AC guide. It does not establish a universal communications fault or a failed component across models.
ESFrigidaire lists ES for an indoor defrost thermistor or humidity-sensor failure.
Frigidaire's room-AC guide gives two possible sensor descriptions for ES. Use the exact model support page rather than assuming which sensor or part is involved.
F1Frigidaire describes F1 as freeze protection engaged.
This protection message is specific to the covered Frigidaire room-AC guide. Do not treat it as a universal sensor-failure code.
F2Frigidaire lists F2 as a freeze-protection display.
This interpretation is scoped to Frigidaire room air conditioners. Check the exact manual if F2 returns or the unit behaves unexpectedly.
HSFrigidaire identifies HS as an air-discharge thermistor failure.
This source applies to Frigidaire room air conditioners. It describes a detected condition and does not confirm which component needs service.
LCFrigidaire describes LC as a communication error between indoor and outdoor units.
This interpretation is limited to the Frigidaire room-AC guide. Use the exact model's support path; do not open the unit or test wiring.
P1Frigidaire says P1 indicates that the room air conditioner's bottom tray is full.
Drain access and handling depend on the unit. Follow the matching model manual and do not move or tip a window unit unless it can be done safely.

Before you act
Air conditioners: Do not open the cabinet, handle refrigerant, or test wiring based on a code summary. Avoid moving a heavy window unit; stop if there is water near electrical parts, smoke, or unusual heat.
These summaries describe the manufacturer's published explanation. They are not a remote diagnosis and do not establish that a specific component has failed.
