thermo king tesco unit fault door code

hi have a client with a second hand tesco reefer sb3 unit shutting down, fault showing [door] in display any ideas no code numbers showing it is a 3 compartment trailer.

Are you refering to the door alarm? That would be a magnetic switch on the rear or side door. It can be cured by replacing the switch, (sometimes, its hit and wires are damaged.), or we have also removed the fuse to prevent further issues. (Customers request.)
Hope this helps.
were are you exactly by the way?
