Customer Question

Yes I have a sub zero 700bf this unit is on a boat and when I power cycle from shore power to generator or back the unit shuts down no interior light no light to control panel . A dim E3 appears on right side display. I have been turning off power to unit for say 20 min. Than it would restart all fine . Over loaded with food I think compressor stayed on too long . It stopped restarting so now I have removed all food and cleaned cooling fans . No frost visible .
