On 12/13/2022 I found that the sight glass was flashing, it means the unit is low in Freon, added 2 lbs. of 404a to clear the sight glass. Started a leak search at the unit and repaired a leak at the Rotalock, on the liquid line. I used some leak lock and tightened up the cap, Freezer went down from 32° to 6° before I left in Round Rock Texas.
