Have both circuits with solenoids for motor cooling staying opened, logged alarms, low superheat, econimizer transducer failure, condenser freeze protection, liquid level sensor failure all with in 2 minutes. When restart the chiller it will run but motor cooling solenoids stay energized on both compressors. Was told it was a board my anothar mechanical company but would like to be able verify which board and learn something in the process.
I am very green on screw chillers, please take into consideration I have to start somewhere.
