Frigidaire laundry center FFLG3900UW1 Dryer will not start.

LED blinks 9 red and 3 yellow.

Unplugging the power for 30 minutes did not clear the fault.

Installed a replacement UI board, but that did not solve the error.

There is no Tech Service Sheet in the appliance.

I want to know what the code means before I purchase and try any more parts.

Is this a good question?

Hi @jjuly ,

Here’s the tech sheet for a FFLE3900UW.

I think it is also for a FFLG3900UW (suspect one is Electric model and the other is Gas) as it shows the gas dryer wiring diagrams as well as the electric dryer wiring diagrams in the tech sheet.

On p.7 it shows a dryer 9:3 error code as being:

MCF checksum error Wrong machine configuration file in main board.

Hopefully this is of some help
