My freezer keeps turning off. When i turn the switch on the panel for "Groupe Froid" off and then turn it back on after a minute, the freezer motor starts again but it is running very hot and turns off after a few minutes. Sometimes it will run for a couple of days until i disconnect from shore power and go for a sail, then it will not turn back on again until i go through the routine of turning the switch on and off a few times. Help! My Haagen Dazs keeps melting!
