The FHWW063WBE is a small window unit meant for bedrooms and offices. Frigidaire’s room air conditioner code guide explains that AS points to a failed room temperature thermistor and ES to a failed indoor defrost thermistor or humidity sensor; the owner step for both is a 30-second unplug reset, then service if the code returns.
Water dripping into the room is usually an installation angle issue: window units need a slight tilt toward the outside so condensate drains away. Weak cooling is most often a dirty filter or coil. The sealed refrigerant system and electrical components are technician work.
