Have a york yvaa that blew the transient suppressor board and all 3 input power fuses. However have performed the catostrophic failure test and drive tests and everything checks ok. Before calling jci would like to make sure there are no other tests i could perform to verify any problems. Also line voltage is consistent at incoming side of the disconnect. Just not convinced there is nothing that caused this.

@timothy-lupa Hey brother,
I posted this in the “screw chillers group”, so all of us get emailed. In the future, if you post in a private group, responses will be a lot faster.
Keep an eye on my post and yours.

Was it a lightening strike possibly ? or some insect , are all other fuses and circuit breakers ok, if so then disconnect the output leads to the compressors and see if you get DC buss and a Low Current alarm when you try to start , you do not need the Transient Suppressor Board in circuit to run the chiller
