I have 2 older models YSDADASA-CLA with liquid cooled Starters. One unit is continually having over temp faults. Pump is new, condensor water lines are free of obstructions and pressure diff is normal, coolant level is full and the heat exchanger was pulled and cleaned. Blew out the heat sinks.

The chiller adjacent is running fine with all temps checking the same.

I would like to ask if anyone has any info on checking the resistors on the trigger board or would have any suggestions on where to locate this info.

Currently the customer has a box fan on the trigger board trying to keep unit online.
