Re: lg f1296tda5
the motor works on a similar principle to a 3 phase induction motor. there are 3 coils in the motor and these are fed from 3 outputs from the control board. the control board turns each of the coils on in turn which pulls the rotor round.
So in simple terms coil A is turned on and the rotor is attracted to it. then A is turned off and B is turned on so the rotor moves to B. then coil B is turned off and coil C is turned on and the rotor moves to C. we then go back to A and do it again.
Its a bit more complicated than that as the coils work together to create a revolving magnetic field that the rotor follows. change the frequency of the field and the rotor will speed up and slow down in unison
so back to your fault. the unit needs 3 phases to work properly. if you lose a phase the motor may run on no load ( but a bit lumpy) but in a loaded situation it wont start as it lacks power
so you have 2 possible faults
1 the stator but not had many of these fail. you can measure the coils to see if they are all there
2 electronic power board. Is more likely you fault
but in all things cant promise if you change the board it will work
hope this helps
