Whats up everyone I'm new on this forum. I'm about 8 months fresh into my new refrigeration job and I absolutely love it.
I have this freezer that seems to have literally stopped me and my coworkers in our tracks
Its a caravell 1 door reach in ice cream freezer with hot gas defrost. This thing has had so much work done to it and its just kicking our asses...New compressor, 3 different cap tubes, new crankcase regulator twice...and the darn thing still wont go below 4 degrees. The refrigerant is 404a and my pressures look absolutely perfect. at 5 degrees I have a 10psi suction and 250 head. just no matter what we do we can't get it to go lower than 4 degrees...
I was starting to think that the hot gas solenoid might be leaking by a little bit but my coworkers don't think so cuz the hot gas line isn't really warm at any degree.
Any advice guys? Caravell is based out of denmark and they won't release any oem details about the cooler. We installed a .036 cap tube by comparing it to the original but something is still not right here i believe
