Important Tips for Frigidaire Models

Window/through-wall units leaking water may be due to leaning too far forward; correct 1–2° backward tilt is advised.

Possible Causes

Clogged condensate drain line

How to Identify: Visible water pooling near unit base and backed-up water in line; gurgling sounds or musty odors sometimes present.

Part: Condensate drain line

Dirty or clogged air filter causing frozen evaporator coils

How to Identify: Restricted airflow leading to ice formation on evaporator coils; water visible after ice melts when unit is off.

Part: Air filter and evaporator coils

Improper installation or unit not level

How to Identify: Water leaks from the front or wrong side of window/portable unit when not tilted back slightly; uneven unit placement.

Part: Unit installation/level

Damaged or rusted drain pan

How to Identify: Cracks, rust, or corrosion on drain pan; leaks even when line is clear.

Part: Drain pan

Full drip pan/tank (portable models)

How to Identify: Portable unit with internal reservoir overflows because it isn’t regularly emptied.

Part: Drip pan/water tank

Low refrigerant levels leading to frozen coils

How to Identify: Reduced cooling performance, ice on refrigerant lines, then significant water when ice melts.

Part: Refrigerant system / coils
