Condensation or sweating on exterior cabinet walls or around door frame

Safety first: Unplug the freezer before inspecting electrical heaters.

Steps:

• Improve ventilation: Ensure adequate space around the freezer and avoid enclosing it tightly.
• Check gasket: Replace if leaking as described in frost buildup symptom.
• Door frame heater: If condensation is localized around the frame, test the frame heater circuit (if accessible) and replace or repair as needed.
• Control settings: Some models have an energy saver switch that disables frame heaters; turn it off in humid environments.
