A humming sound could indicate the compressor is trying to start but failing, which might indicate a start capacitor problem. A technician will be able to diagnose it.

Refrigerant Leaks

Refrigerant is what makes the showcase cool. A leak means you'll lose cooling power, eventually resulting in the showcase not cooling at all. Signs of a leak include the showcase not getting cold, even if the compressor is running, or a hissing sound. If you suspect a leak, contact a technician immediately. They can test for leaks and refill the refrigerant, but this is a job for a professional.

Frost Build-Up

Excessive frost build-up inside the showcase can be a nuisance and can indicate problems. This can be caused by a faulty defrost system, door seals not sealing properly (letting in warm, moist air), or the showcase being overloaded. Inspect the door seals for any damage or gaps. Check the defrost system for any malfunction. Clean up the frost and remove items if the showcase is overfilled. A faulty defrost system will lead to frost building up, and so you should have it checked. Excessive frost can also affect the showcase's efficiency, making it work harder and consume more power.

Water Leaks

Water leaks can be due to a clogged defrost drain, or problems with the condensation pan. This is especially true if you see water pooling inside or around the showcase. Look for any blockages in the defrost drain. Clean the condensation pan. You can unclog the drain with a wire. Leaks can not only damage your showcase but also lead to other problems, like mold. If the water leaks persist, you may need to consult a technician.

Issues With Temperature Control

If the temperature fluctuates, it can be due to a faulty thermostat, improper door seals, or an overloaded showcase. Check the thermostat setting and make sure it's accurate. Inspect the door seals. The door seals prevent warm air from entering and compromising the temperature inside, and this can be crucial for the showcase's effectiveness. Overloading the showcase can also affect its ability to maintain a consistent temperature. Ensure that the showcase is not overpacked, allowing for proper air circulation. A faulty thermostat can lead to the temperature fluctuating, and that is why you should always check if it's working properly. A consistent temperature is critical for preserving the quality of the products inside.

Door Problems

Doors get a lot of use, so it's common for them to have issues. Problems include seals that don't close tightly, broken hinges, or the door not closing at all. Inspect the door seals and replace them if needed. Check the hinges and tighten or replace them as necessary. Make sure the door closes securely. Properly sealed doors are key to maintaining the showcase's temperature. Ignoring these issues can lead to wasted energy and spoiled goods. The doors should close tightly.
