Compactor would only stop and reverse if you turned it on and off. Very noisey.

First let me say that I read many of the other posts regarding this repair and without them I wouldn't have had a clue how to fix this. Since the ram apparently moved up and down when I shut it off and turned it back on I reasoned the directional switch must be the problem. Ordered the part, Quick delivery. To replace the switch I removed the draw and removed two screws on the frame that hold the control panel in place. Lift up to remove. My unit is a stand alone unit although it is installed under the counter. There are two additional screws to remove the top and expose the ram and power screw drives. To remove the directional switch from the control panel you need to remove two hex head screws that hold it in place. This is a little difficult because of the small space. With the help of a small nut driver I was able to remove it. Note: the screws are held in place by a flat piece of metal that acts as a nut. Be careful not to drop it. Then simply remove the wire leads (all color and letter coded) and remove the switch. I was careful to reattach the leads to the new switch as I removed each one. Be sure to replace the switch with the limiting lever in the same position as it was in (it is vertical). Put everything back together and you should be good to go. That didn't happen for me! Problem persisted! Next on my list was the power nut. I got access to the ram and power screw drives (see above for instructions). The two power nuts are plastic wing nuts that are held in place by metal covers. The metal covers are each held down by two hex head screws. To gain access to the power nuts you have to remove the metal covers. Note the position of the nuts in relationship to the power screw shafts so that when you reassemble it they will be in the same position as when you started. In my case the top of the screw shafts were even with the top of the power nuts. (CAUTION: the ram is held by this assembly. Depending on what position your ram is when you started this repair it may fall! My ram was in the up position and when I removed the second cover it slammed down to the bottom of the drive screws). My advice is to be prepared by bracing up the ram before removing the metal covers. No harm when the ram fell but it did startle me. I then removed one of the power nuts. It was split in half. The other nut was fine but I decide to replace it anyway. Ordered parts. Quick delivery. Before I attempted to replace the power nuts I removed the ram (it just lifts out) and cleaned every thing. I put some new grease in the places that I had removed it. Then sprayed WD40 on the power screws. When I put the ram back in, I broke the new directional switch I had put in. So be careful!!! I still had the old one so I ultimately put it back in. I then replaced the power nuts. This was a little difficult because I had to hold the ram up while I was putting the metal covers back on. I would suggest you either brace the ram or get someone to hold it while you put the metal covers back on (In retrospect I suppose I could have just put the nuts on when the ram was down). Reassembled everything. Should be good to go. That didn't happen for me! Problem was still there! I turn it on, ram goes down. I turn it off, ram goes up. Desperation!! The only other thing it could be is the drive gear assembly. Ordered parts. Quick delivery. The gear drive is on the bottom of the machine. Lay the machine on it's side to gain access to the bottom cover. There are 5 hex head screws that hold it on. Remove screws and cover. It's pretty simple from here. The drive gear was missing a few teeth but the rest were in tact. This explains why the ram was still moving up and down and led me to believe it was something other than the drive. The only difficult part was the removal of the pin in the drive shaft. I wound up using a bolt the about the same diameter and a hammer to drive it out. Then just reassemble. There are some instructions that come with the gear parts that tell you how to set the spacing in the gears but I had no problem just replacing the parts without making any "adjustments". Should be good to go! Yessssss! Everything worked perfectly!!! My final words of advice. If your machine has this problem CHECK THE DRIVE FIRST. It the easiest thing to do because you can visually inspect it and know or eliminate it as the problem. It's about a 5 minute job and can may save you some of the problems I had. A big thanks to PartSelect for sponsoring these posts. The repair company that I normally use told me the machine was too old and probably wasn't worth the $100 just to come out and look at it, never mind the additional cost to repair it. All in I spent less than $100 and had I checked the drive first, I could have been done for less than $30.

Replacement handle fit perfectly, removed the old one by taking out two screws. I was glad that the part was still available, although a little pricey, because the unit has to be at least 25-30 years old or more.

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..

Laid compactor over on its side. REMOVED 5 SCREWS holding cover plate to expose gear drive. Found that large drive broke in half. Used screwdriver to start split ring then pliers to pull it off the rest of the way.Take off the washer . Next I needed to losten the 4 nuts holding the drive motor. This allowed me to slip the rest of the drive gear off the drive shaft. It was then a simple matter to put the new gear back on the chain then slide the whole thing back on the drive shaft. Replace the washer then slip the split ring back in place and seat it home with the pliers. Retighten 4 nuts on motor support. Put cover back on with 5 screws 2 in front 3 in back Pushed button it worked.I must mention that this was a Sears compactor but when I went to their online parts they no longer supported it. I found Part select and they suggested I look at a Kitchenaid compactor and after checking out the picture it looked the same,Iordered the part and it was the same. Thanks I guess I'll come to you first now.

There were no instructions that came with the parts kit other than how to set the spacing for the gear lash. There were parts in the kit which I have no idea what they are (4 inch long plastic pipes?. Having 4 years experience with Sunbeam appliance repair was an asset. The old melted and broken gear came off easily with a few strikes of a hammer on a flat blade screwdriver. The replacement gear was a perfect match and the scroll pin was put in with a little gusto effort (tight fit as it should be). It would be great if just one gear or the other could be ordered....

After inspecting to make sure the actuator was functional and that power to the unit was not an issue I was able to find that one the drive gears cracked in half and made the compactor inoperable. It was easy to remove the bottom casing with a nut driver. This casing covered the drive gear which operated the ram. After slightly loosening the gear mounts and I was able to replace center gear and re-attach gear chain and re-tighten. Then replace bottom casing and the compactor was back in action. Huge savings!
