Reefer container

Hi,

wondering if any one out there with container experience might have some ideas on this.

I have a Carrier "489" model microlink 2 reefer I hire now & then.

It blew the supply transformer which I replaced and everything operates fine except.....

When I go into pre trip all come up as fail even though everything is in order when I check current and voltage etc.The container runs down to temp, dfrosts etc all ok

I'ver tried another processor but still the same. wondering if anyone has a thought on it.
thanks
Regards
