Frigiboat evapaortor dripping water

I have a frigiboat keel cooled and the refrigerator cools to 37f but between cycles the evaporator thaws and drips water. With compressor running the plate shows a fine layer of frost over 100% of it. I have checked for any air leaks into box and all appears to be good. Any ideas would be appreciated.

Re: Frigiboat evapaortor dripping water

The thermostat, when properly clamped to the evaporator plate starts the compressor when the plate reaches a temperature of approximately 15 to 45 degrees F, depending on where you set it. Obviously, part of that range is above the freezing point of water and, when set that high, the plate will drip water until the compressor starts. If you don't want it to drip water, you need to set the thermostat to cut in below about 32 degrees F.

The extent of the frost, that you say is 100% is a function of the amount of refrigerant in the system (100% is at least a full charge). The thickness of the frost is a function of the door seal, the frequency of opening the door, and the humidity.

Hope that helps.
