Reach in Freezer Problem *Help*

[SULTAN]

I got a coldtech reach in commercial stainless steel freezer. Its charged with 404a. compressor comes on fine. I touched the condenser and liquid line and its frigging colder then the evaporator!! wth is going on? Can someone guess what it could be?

Sounds interseting, check if system has hot gas defrost system incorporated, may be that controller has failed to continuous defrost, or possibly the reversing valve has jammed/failed in defrost position. First thing is fit a set of gauges to system and see whats going on. Both suction and high side gauges.

Is the liquid line colder after or before the dryer?

If the liquid line is cold it would suggest a blockage init somewhere.
