my electactic drink fridge isn't getting cold, the dial is on 7. help?

First, verify installation conditions. The ambient temperature must be between 60°F (16°C) and 90°F (32°C). Ensure the unit is plugged into a grounded 3-prong outlet on a dedicated 15-amp circuit. Check that the front ventilation is completely unobstructed and the unit is leveled using the adjustable feet. The temperature control dial ranges from 0 (warmest) to 7 (coldest).
