Question about True 72 cu. ft. / 2039 liter Commercial Freezer GDM-72F
I have a 72cu 3 door reach in freezer. Put in new freon,cleaned and vacummed all system and the freezer still does not freeze. Compressure running and holding pressure. Cannot think no more !!
Marc is correct, you should check to see if you have a blocked filter (this should always be changed when a system is vacuumed and refilled) or you may have oil in the line(s) causing the blockage. But you should know that there is a blockage because your low side pressure will be lower than it should be or in a vacuum and your high side pressure will be much higher than it should be. The blockage could be oil, or a plugged filter or even moisture in the system which will freeze at the end of the capilliary tube in the evaporator which blocks the flow of the refrigerant. But if this was the case the freezer would start to cool down but only for a short time from first start-up then warm up as the capilliary tube plugs up with the frozen moisture. I would suggest that you remove the refrigerant, purge the system to be sure there's no oil etc int he lines, remove the old filter and install a new one, put the system into a deep vacuum for several hours, refill the sytem with the correct amount of refrigerant and monitor it to see if there's a change. Good luck

Can you check if there is a frost pattern on the coils? May be a plugged system line or dryer.
