LG side by side Model # LSC26905TT

[SKYLINE1980]

Any one familiar with the LG side by side M# LSC26905TT ? Im hinting towards the main mother board but thought Id get some advice. Freezer completely covered with thick ice. Evap fan motor doesnt activate while compressor is running. I have continuity on my defroster heater connections but defroster heater never activates. This mother board controls literally everything. The defroster timer and relay, evap fan relay, ect...

Part 401A  test it and clean ice off evap motor and test evap fan

Not getting any voltage to the evap fan motor coming from the board. Just curious, would the freezer compartment  over freeze to a block of ice due to the evap motor failure or could this be 
A temp control sensor issue or circuit board failure ?

I do have continuity to my heater defrost terminals

I thought about replacing the board and evap fan motor at the same time just to be on the safe side. Even thought that maybe fan went out due to all the ice that formed around it

Evaporator fan motor will not get voltage all the time in it's current state.  It is probably in an error mode right now and waiting for service.  You will need to clear out all the ice from the evaporator first and then start up the unit to check the fan motor.  Check the defrost heater and defrost controller for continuity.

Check the evaporator fan and see if you can turn it by hand.  If not, moisture has gotten into the bearing and has frozen the motor.  You will need to replace the motor.
