Master bilt freezer giving error code p2 - Master Bilt Freezers

SOURCE: Master-Bilt Freezer doesnt cool enough

The only thing I could suggest is looking at the evaporator (inside coil / cold bit) and making sure it is not frozen over reducing the airflow through the coil. If it is then put it onto a couple of defrost cycles to clear the ice build up. Not sure exactly of this type but would assume you also have a sight glass on the external unit, you can check this to see if when running the sight glass is clear (fully charged). Another check is looking at the compressor and the larger of the two lines (suction) should be cold back to the compressor (this line is normally insulated). However I would suggest your best course of action is a good refrig. techy. Hope this helps.
