My washer works through all cycles except spin. The door lock light comes on and door locks firmly, it agitates in both directions properly, the drain pump works and drains the water with a strong flow from the drain pipe. It just won't spin whether it is loaded or unloaded. If I try to start cycle with door open it gives me the open door warning. It's a front loading frigidaire gallery series, I'm not sure of the age as it was used when purchased. Any input would be much appreciated.
