Maybe not insane, but I have to drink warm beer on occasion
Nova Kool LT 200
When I turn the unit on, it runs (and cools) anywhere from 5 minutes to several days. When it works right, it cycles properly keeping a constant temperature.
I checked all the wires, checked the voltage.
Shutdowns have occurred with fully charged batteries and low batteries, plugged into shore power, cool days in winter, warm spring days, other appliances running or not, beer in the fridge or not.
When it stops running, every three or four seconds there is a one second high pitched squeal. The unit will not restart by itself.
At this point, I turn power off and then back on. Sometimes it starts right away, sometimes it takes a long time flipping the breaker off and on.
