  If the cooling capacity of your Waeco Freezer is dropping and the interior temperature is rising, consider these possible causes and solutions: * The vaporizer may be iced over, requiring you to defrost it. * The ambient temperature may be too high. * There might be insufficient ventilation, so move the cooling device. * The condenser might be dirty; in that case, clean it. * If installed, the fan may be defective and need replacement. * The battery capacity might be exhausted, so charge the battery.
