I have an Affinity Frigidaire Front Loading Washer. After an off balanced load the washer never resumed its cycle. I tried a "Drain and Rinse" cycle. The sensing light never illuminated. It seemed to start fine but the spinning never happened. I pulled the back panel and discovered the belt to be in perfect condition; not the belt. I found some wires smashed and copper showing where the drum made contact. Ah ha I found the problem. I repaired the wires and also inspected a bit more to find nothing else visually abnormal. Buttoned everything back up and plugged it back in. In the mean time I also purchased a new door latch/switch (I heard that was a quick solution too ). Neither the new part or wire repair solved the problem. So here I sit...stooped and frustrated with a Sensing Light not lit.
Possibly your door latch PTC sensor isn’t giving a good signal to the control board. Use a meter and test to see if the door latch is working properly.
