I have a Vitrifrigo DW70 drawer freezer installed on my boat, and it is not working properly. Any smart folks that could perhaps confirm my thought that it's low on refrigerant?
DW70 drawer freezer, separate condenser unit, AC/DC power. Uses at Danfoss Secop BD35F compressor.
Symptoms:
I did notice a little corrosion on the compressor around the seam between the top and bottom parts but nothing major.

Symptoms:
- Unit will not get cold. Worked before the boat was winterized. Does not get cold after de-winterization.
- Temperature only gets to about 50F after many hours (days).
- The cold plate is slightly cool, but not cold. No frost, no condensation.
- The compressor runs continuously.
- The compressor gets warm to touch (not hot).
- Lines coming out of the compressor are neither hot nor cold.
- Fan runs.
- Radiator fins are clean and clear of any debris.
- Compressor has plenty of ventilation.
- Jumping the thermostat to force the compressor to run had no effect.
- Using a known good 12v LED lamp to look for error codes had no result. LED did not light with error codes.
- Confirmed compressor has continuity and no open shorts (it's running, so not surprised).
- No difference when running on DC or AC power.
