freezer repair

Freezer runs and shuts down and not freezing

no thats not the problem

It,s a upright freezer only. And not getting cold enough and sometimes it quits running.

Try shorting the cold control and measure the stabilized freezer temperature, just may be a bad control, but suspect a bad compressor/ refrigerant leak.

That last answer sound more like it. can it be repaired by home owner or recommend professional help?
