Product Description

Power Nut Specifications

This part is a power nut, and it is intended to be used in conjunction with trash compactors. The function of this nut is to fasten to the side of the ram where it is threaded. When the power screw rotates, it is fed through the power nut, which pulls the ram down to compress the trash. This part is just over an inch in diameter, and is just one inch thick. This part is white and made entirely of plastic. The reason for needing to replace this part is if your compactor ram gets stuck, or if it does not stop at the end of the compacting cycle.

compactor would not compact the trash
took appliance out of cabinet, found the problem to be two nuts on the big screw bars that drive the compaction machine up and down. These things were wore out. We replaced them and turn the electricity back on and tried the compactor and it worked perfect. Of course here was to top cover that had to be removed and reinstalled . all in all it wasn't to difficult. A new machine cost 1100 dollars. This old one bought in 1988 cost 350 dollars. so thank God this fixed it.

Install NewDrive Gear Kit,( I also added,2 poor nuts and all 4 wheels)
My compactor is quite heavy, I moved it onto the kitchen floor unplugged and removed the cover plate from the bottom exposing the drive gears. The small (pinion ) gear was stripped as well as a section of the drive gear. I followed the video and removed the (fulthy) ram. The interior filth was so great I removed all parts to my garage and spent a lot of time cleaning them especially the ram.By the time my parts arrived, it was all clean and ready to go. I had also found that one of the power nuts was broken and had ordered new wheels and power nuts. Assembly was straight forward and it works like new now,

a plastic bag got caught around the screw and the flange on the nut broke so it couldn,t raise one side so the door was jamed at an angle
I pulled the unit out and tipped it over . I pulled the pan off the bottom then i could put a box end wrench on the screw that was jamed then tuned the screw to loosen the door . i then removed the plastic bag that was wrapped around the screw and put the new nut on and all fixed

Trash Compactor ram will not move while motor running, stripped power nuts
Move the unit out of the cabinet, and take off the top cover.The two drive screws are easy to see. unscrew the two screws of one of the power nut covers and remove that cover. With pliers, unscrew the plastic power nut from that screw. Screw on the replacement power nut with the help of pliers and some heavy grease. install the bearing cap. Use the same procedure for replacing the plastic power nut on the other screw. To make sure the piston is level, place the cover on the power screw but do not attach it. Measure from the end of the screw to the top of the cover of the first screw, then adjust the second power nut up or down so the two power screw nut covers are the same distance down from the top of the it's power screw Lift up the piton assembly to close the gap, if any (I used a short piece of rope) , and install the screws on the second power bearing cap. After installation. recheck the distance from the top of the power screws to the power bearing caps is close to the same distance so the piston will be level.. This same procedure could be followed for other brands. Power of the appliance and verify functionality, if OK replace the top cover and push unit back into the cabinet..

Power nuts stripped
Only needed a flat blade screwdriver and a socket set to remove the top and the "cages" that held the power nuts. Failed to properly restrain the ram but didn't effect the repair. Installed the new power nuts outside of the unit then placed the ram assembly on the worm screws and all was well. Applied grease to the worm screws after assembly.

Ram Stuck in Mid Position, motor not able to move.
Removed unit from under counter. Moved to garage. removed Top, Bottom plates, and switch controller. Turned upside down and removed power screw nuts One came off easy. One side frozen. Took large pliers and worked nut off of drive screw. Removed ram. Ordered two new power screw nuts. Lubed screws, chain, nuts, rollers and cleaned whole unit. Straightened ram which was bent from so many years of use. Unit 26 years old. Replaced all plates and plugged it in. Works like a champ. Thanks for carrying parts for a unit this old.

Grinding sound when operating compactor
Removed drawer first, then removed compactor from under kitchen cabinet. Removed top cover. Discovered that a small wash cloth was wound around one of the drive screws. I then removed plunger and put it back in position. Replaced top cover and turned on compactor. Plunger went to the top and made a grinding sound. I removed the cover to discover that when I put the plunger back in, I did not have the lever that trips a micro switch in proper position. I needed the replacement plastic gears that were ruined when compactor did not shut off. Relatively easy job if I had noticed the location of the shut off lever, and would have needed the parts.

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

Description of part number ps11744741 indicates this quantity of 2 wp777533 power nuts, is this correct. I do need 2.

Hello Terry, Thank you for the question. Very sorry but I am not showing anywhere in the description that it states it is sold as a set of 2. This Power nut is sold individually. Hope this helps!

Not a question, but your part number PS11744641 is also a direct replacement for the power nuts on the Frigidaire tcu 3h. I guess there are not many oems producing the power screws and nuts. It's also the same nut as Whirlpool part no 777533
For model number Frigidaire TCU-3H
PartSelect logo
Hi Ray, Thank you for the statement. Actually I see that part number PS11744641 is a bake element while part number WP777533 is the power nut that you are referring to. Some times manufacturers will make parts for other manufacturers but in your case Frigidaire does not offer a replacement for the nut that originally goes with your appliance. That part number is: 5308003543. I hope that helps!

My compactor made a loud racket. I found the pinion and main drive gear were slipping and teeth were worn. I will order new ones from you, but I wonder if my power nuts ($$$) should also be replaced.. I suspect they are much easier to replace should they fail later.
For model number TU8000XRP1

Hello Michael, thank you for your question. We do recommend replacing them at the same time. We hope this helps!
