GE Air Conditioner: leaking water

Professional Repair Guide

What is this symptom?

If your GE air conditioner is leaking water, it may be due to several common issues like improper installation, a clogged drain line, or a dirty air filter. This can result in water pooling under the unit or dripping indoors, which requires immediate attention to avoid water damage and ensure the unit operates efficiently.

Urgency: Medium

Important Tips for GE Models

  • GE owners are specifically advised to ensure adequate tilt/leveling since GE units are designed to drain rearward.
  • AWCS12WWB specific reports link leaks to clogged or frozen evaporator coils.

Possible Causes

Improper installation / unit tilt

How to Identify: Water pooling on the interior side; unit is level or tilting inward rather than slightly downward toward exterior. Check with a level tool.

Part: Installation orientation and unit level

Clogged condensate drain line or drain hole

How to Identify: Water backing up into unit, visible debris when inspecting drain hole/line; gurgling sounds.

Part: Condensate drain line and drain channel

Dirty or clogged air filter restricting airflow

How to Identify: Dirty filter visible, reduced airflow, possible ice on coils, then water leak when melting. (

Part: Air filter and evaporator coil

Damaged, rusted, or misaligned drain pan

How to Identify: Pan visible rust/cracks; continuous puddling even after clearing drains; inconsistent drainage path. (

Part: Drain pan

Low refrigerant causing coil freezing and melt overflow

How to Identify: Poor cooling performance, hissing sounds, ice formation, then water leak as coils thaw.

Part: Refrigerant circuit / evaporator coil
