got a trane tracer system, controls some chill water units and two trance screw chillers in a factory i am working in.it seems that the tracer system controls the opening of the chill water valve on each unit. it opens the valves by a solenoid actuator,only half of the solenoids are functioning, so i removed the ones that dont work and used a plastic ty-rap to hold the valve open so the chill water goes in the coil. now i have another problem, it seems the activation of the blower fan is also controled by this tracer. please keep in mind this company is very poor as in no money for parts, i want to know if anyone one out there can tell me if it is possable to by pass (jump out) the part of the circuit board that controls the fan comming on. the tracer system cant be fixed properly as they refuse to by parts or call the trane service team to come in and look at this problem. (they owe trane 20,000 and wont pay...) i am the junior mechanice, its the weekend, i am alone, can any one help me out with a fix as to getting the fan to stay on for more than 5 minutes. thank you for your time.
