We are at our refrigeration
wits end! We have a 2007 era frigoboat keel
cooled system. One for fridge and one for refrigerator
. Both have caused mild problems in the past usually to do with moisture in the system that has been easily fixed. But this season we returned to the boat
in Trinidad after 6 months on the hard
to discover that the fridge was not performing as last season. Basically it takes about an hour or more to drop one degree at full compressor
speed (6 bars) and pulling about 8 amps. This draw is fine when plugged in but on the hook it eats at our batteries
as the compressor
is on full draw for 12-16 hours a day. By comparison the freezer
takes 6 to 7 minutes to drop 1 degree at 2 to 3 bars of compressor speed, 3-4 amps. Is only on for a couple of hours a day.
We have had many expensive hours of the our Antigua-based Frigoboat service
agent crawl all over the unit. Changed all filters, vacuum pumped for 24 hours, tested thermostat, tested compressor function, gas charge ok. All good. Insulation
seems to be fine. Keel
plate clean. plate in fridge has even frosting and healthy gurgling sound, suggesting that is not blocked. Fridge does get down to set temp (38 F) eventually but the power required to get there and stay there even with infrequent use is not sustainable for us unless we run our generator
Anyone have ANY idea what might be wrong with the system? (BTW compressor, thermostat and controller are all about 1 year old, all seem to be fully functioning. Anyone had a similar experience and fixed it?!
