GA90+ Fan motor overload open fault will not clear

I have a GA90+ Fan motor overload open fault will not clear.


I am working on a ga 90 +. It was continuously shutting down on fan motor overload open. I replaced the overload relay but the fault will not clear. This unit does have a variable speed Drive for the fan.

If anyone has any suggestions I am listening.

Does the motor (M2) try to turn at all?

The error suggests to me that it is somehow disconnected - the "open" in error message.

Let us know if/when you get it fixed and what the fix was, please.
