What is a common issue with coolers and freezers that use a coiled discharge line in a pan for condensate removal?

The issue of leaks from water corrosion is a common concern with coolers and freezers that utilize a coiled discharge line in a pan for condensate removal. In this configuration, water can accumulate in the pan and may not drain effectively, leading to stagnant water conditions. This stagnant water can contribute to corrosion over time, particularly if the materials in the discharge line or pan are susceptible to rust or deterioration when exposed to moisture.

As corrosion develops, it can create small leaks, which can lead to further complications within the refrigeration system, such as loss of refrigerant and compromised efficiency. Maintaining and ensuring proper drainage from the pan is crucial to prevent such corrosion from occurring.

The other issues, while they may seem relevant, do not directly stem from the specific design choice of using a coiled discharge line for condensate removal in coolers and freezers.
