Doors not sealing, internal condensation, and freezer snow

Replaced both door gaskets and cleaned condenser coil

The result

Eliminated moisture and snow, restoring normal cooling

01

Customer Complaint and Possible Causes

The customer reported that the refrigerator doors were not closing completely, along with internal condensation in the refrigerator compartment and snow accumulation in the freezer. Potential causes for such symptoms can include improper door alignment, damaged hinges, or worn door seals allowing warm air to enter.

02

Diagnosis and Findings

We checked the panel temperature against a digital thermometer reading, confirming they matched. We inspected door alignment and seal contact across all planes, finding them properly set. We checked sagging doors or deformed hinges, as alignment was correct. We found that both door gaskets were worn with multiple tears, letting warm air inside. Additionally, as part of our full diagnostics, we discovered a dirty condenser coil.

03

Repair Performed

We replaced both door gaskets. We also cleaned the condenser coil using a specialized rinse-free indoor cleaner as part of the technical area maintenance.

04

Verification and Outcome

Post-repair checks confirmed normal operation with no further snow or condensation buildup, and that no further work was needed.
