Hi all, just need your assistance. as i've a case that shipper get un professional technician and played with the reefer equipment of the carrier. after my reefer contractor checked the container he advised below. so can anybody advise if below is true and could be done
============quote================
We found that the customer has actually played with the unit’s control wiring which has resulted by having the evaporator motors rotating in the wrong direction, we have repaired the wiring and the evaporator motors has returned to their normal rotating direction!
The negative results which we may have resulted if the container is kept by the wrong wiring: having the supply air going UP instead of DOWN and accordingly the supply air sensor will be reading the return air temperature and the return sensor will be reading the supply temperature, and cargo will never reach the setpoint!!!
On the display you will see that the unit is inrange and achieving the setpoint and everything is normal, but actually this is a fake readings resulting from having the motors rotating in the reverse direction..
It’s totally not recommended to let the customers play with our reefers..
