Glacier Bay refer/freezer HELP !!

[Sidewinder]

Hi folks- This is my first post in this forum so bare with me. Is there anyone out there who as experience with Glacier Bay refer/freezers. After leaving my s/v Sidewinder ( Fastpassage 39 ) on the hard for a few months I came back to her and found a small puddle of yellow fluid at the bottom of the freezer. I have been told it's the mixture inside the cold plate that is like anti-freeze. I can't find the leak and fear it is on the back side of the cold plate but have been told that is it only leaks while the unit is turned off the leak could stop when the fluid returned to it's slushy or solid state that it has during normal operation. I haven't been able to locate a fill port to check the fluid level and I don't know what that level should be. Any ideas out there ?
