Hi, good morning,
The issue is not likely due to a leak.
This is caused most of the time the temp setting being too low.
If you have tried adjusting this without success, you will need to have this one serviced because also low Freon (refrigerant) will cause this issue as well. I know this issue well.
In any case, I will stick with you until this is complete.
