FWT645RHS0 Slow/ incomplete Agitation no spin

[ronovabch]

Hello I have a Frigidaire Front loader that will agitate but in a manner that the drum seems to move 1/2 rotation  turn at a time,  Then will not spin

It will pump out.   I found a broken spring and replaced that along with the shock absorbers as it seemed that the drum was bouncing around excessively.  Sp can the speed control board cause these issues?  I have not checked the door switch however since it does rotate albeit half heartedly that would seem to work. Any Hints?

Also theTech Sheet was damaged when water leaked from the detergent cup when the spring broke so i can only read about half of it.

Since a spring broke and also if it’s the spring on the opposite side of where the motor speed control and main motor is located ,  I would inspect all the wiring and check for continuity on all of the motor wiring end to end and the wiring from the motor speed control to the motor .  There may be a chance that the tub moved around so much up and down, that the motor may have smashed up against the motor speed control and broke a wire . The wires can also be broken in side the wire sheath it self .  Check for any possible abrasions on all the wiring from the motor to the motor speed control.  I would start there first for any visible signs of damage before doing anything else ,

Ok thanks will do!

thanks did not see anything did check resistance of the cables between the board and motor and they checked out ok ...checked  the speed control board shet said   at least 3Meg ohms between 1 and 2 and 2 and 3  3 and 1 all seemed about 0.1 Megohm on my cheap multi meter so it may be the culprit

You may need to use a better meter by the way and recheck each motor terminal again for the correct indicated reading off the tech sheet again.   Post back what your diagnosis is and the correctional fix you came up with if you would,

So I was able to find an electronic copy of the Electrolux Service Manual for Tumble action washers; 2002 edition on the internet it had a handy dandy trouble shooting chart:  Washer Tumbles Slowly in Any Timer position. 

 The chart said disconnect ten pin plug from the control board and check resistance between pins 3 and 4 of the plug . if 184 Ohm +/- 7% you have a defective board.  Readings other than  if 184 Ohm +/- 7% then you have a defective Motor .   Mine Checked in at 183 Ohm. 

Ordered up a controller put it in and now back in business,  instead of a  700 dollar washer!

Thanks for your help !
