The compactor would only stop and reverse direction if you turned the switch off and on again

I slid the compactor out of the cabinet space it sits in and unplugged it. I removed the two screws that hold the control plate on and it then lifts up and off to reveal the screws that hold the top down. Then I removed the two screws that hold the top of the unit on and removed the top. I then put the switch plate back on and plugged the unit back in and ran it so I could see it operate from above. It went all the way down compacting the drawer but kept running and did not reverse and come back up. I figured it was the directional switch and ordered that. The plastic power nuts that the unit rides up and down on looked worn so for $10 each I ordered a pair of them also. The parts arrived in 3 days. I decided to install the power nuts first. When I removed the metal casing that holds them I saw that wings on the plastic power nuts that hold them in place in the metal casing were all broken off. I installed the new power nuts then plugged it back in and ran it. It cycled perfectly. luckily I had not opened the directional switch and I was able to return it to Partselect for a refund. In total I had to remove and reinstall 4 very short screws and 4 small bolts. While I had it out and apart I also cleaned out quite a bit of old trash that had escaped to unseen parts of the compactor. It is 26 years old and working fine. I don't think they make them like they used to. Thank You Partselect for a great experience
