Hi all

Having some problems with an Aermec chiller. Basically was called to an Aermec chiller cooling the water pumped through a small AHU as part of a close control humidity and temp system. The chiller had tripped out on LP and one of the condenser fans run capacitor had melted or broken away and was lay in the bottom of the panel. When I put my gauges on had 200 PSI on both the discharge and the suction. When the compressor runs the suction pressure drops off to below zero preventing the fans from running and tripping the unit on LP. Once the unit trips the pressure slowly equalises to 200 psi once again. Head of the compressor and the discharge gets red hot, have replaced the capacitor, checked the system charge which is correct. Was thinking there was a problem with flow around the evaporator but the water pump is running. Im thinking TEV faulty which would be a major pain to replace. Am I missing something else or do you think the TEV is the way to go.
