We have a Screen 4300S, it runs well for more than 1 years, but recently, errors happened all the times.
We make lots of effect to control the temperature and humidity. But it seems doesn't work.

Very rarely, in the summer here, we take off the right side cover to lower the internal humidity.
YMMV

We are located in NY, it is extremely cold in Winter and Spring. That is why we need to turn on the heater to keep the room temperature around 70 F. But we have no idea if the machina overheat or in low temperature,. The errors just happen all the times.
 
For the blower error, first try to turn off-on your machine to check. If error still appears, check all cable connections. You can open the blower unit to check if the inverter is responding or if some data is being shown. There are also cables inside the blower unit so you better check it. During initialization if you hear a tick sound, that is the signal for the blower to start. If the motor did not start and no response from the inverter then most probably the inverter is at fault.

Oh, yes, I think it is the reason why we need to re-start the Machine for several times. Can you tell me how can I check the inverter is working or not.
Thank you for your reply, it helps.
 
Open the blower as ronnie said, then go to service menu > actuators and start-stop the MBL1 (drum blower) repeatedly keeping an eye on the inverter.
