FIXING COMMERCIAL TRUE AIR FREEZER
Check your CRO . The compressor may be getting high suction pressure on start ie: like out of defrost. should be set at no higher than 40 psig. you can even drop it to 30 psig. You may have to install a valve
before the CRO to see evap pressure before the CRO valve. If it does not have a CRO you can install one with a CROT-0/60. It has an access on it.
