Found Prep Table unit unplugged with a sign do not plug in. No one at Panera knew what was going on with the unit The compressor terminal cover was loose so I tested the windings on the compressor. Plugged the unit in and found the suction pressure went below zero within a minute. Unplugged and leak tested. Added nitrogen to 220 psi and leak checked again. While leak checking found the evaporator fan motor and blade missing. Need a new fan motor , fan blade and to evacuate and weigh in a charge if the pressure holds. Need one. 800402 fan motor and a 801002 blade. 7/27/20 Return to replace the fan motor and found unit was completely out of charge. Troubleshot and found discharge line close to the compressor was leaking. Repaired the leak and pressure tested system at 150 psi for 10 minutes, no sign of leak. Released the nitrogen gas and pulled vacuum on the system, charge unit to manufacturer's spec. Started the unit and checked unit operating pressure, unit is working pro
