Start your investigation by removing the bottom plate. There should be a belt or chain going around 3 gears. Mine has 2 metal and one plastic. The 2 metal ones are on the ends of the rods that the ram runs up and down on. The plastic one is on top of a big speed reduction gear that is turned by the motor gear. Don't pinch your fingers but see if you can turn the big gear by hand. All gears should turn. If not check each gear for broken teeth, or bad bearing & races under the 2 rod gears. Be sure to check the threaded hard plastic nut that drives the screw that powers the scissors up and down. This is the part that usually fails.
Trash compactors can be a very nice feature and addition to your kitchen. However they can also be very hard to work on if they go bad. There are 20 some brands of trash compactors available, but the KitchenAid trash compactor is one of the most common.
If your trash compactor does not work at all here are some things that you will need to check.
First off make sure that you are getting power to the unit. Many are plug into by code a GFCI wall socket. These outlets do a great job of protecting against shock, but do a terrible job of staying on, especially when used on a motor that pulls a high amount of current when starting. It is not uncommon for them to go bad and trip for no reason at all after a few years. If the outlet is tripped, try to reset it by pushing in hard on the reset button in the center of the outlet.
If you have power at the outlet, then you will need to check through the circuit in the compactor. This can include a door switch, micro switches that sense the position of the ram, and possibly a key switch. Make sure that there is nothing stuck behind the drawer that would keep it from going fully shut. Check the position of the ram to see if it has returned all the way up.
If your ram is stuck down or if it will not go down, check for broken drive gears, belt, of chain. Make sure also that the switches that sense the ram position have not move and come out of place.
Your trash compactor will also need to be clean periodically. Food spilling on the tracks or glides can cause the drawer to slide hard or even become stuck. Clean all the slides or glides, wheels tracks and such with warm damp cloth and the re oil everything with a household lubricant. With time and use the wheels and bearings may also need to be replaced to keep your trash compactor operating well.
the running cycle for this type of trash compactor is a max of about 30secs. The fuller the bag is the shorter the cycle. However, if this is not how yours is running try checking to see if there is any trash stuck between the ram and the basket. Or make sure that the foot peddle is still staying in the "up" position.
at the top, above the ram, there are two switches. One is the reversing switch (should have 4 wires), the other is the stop switch (2 wires). I suspect that the switch arm is bent, due to what you just described, and fails to activate the switch to stop the motor when the ram is at the top position.
Most likely the motorwindings have been overheated after staying to long time in down position and trying to get up.
If there is a Emerson motor in your compactor than you will not find anything wrong most likely it is the winding of the motor, we have had this two times, changed the motor and the problem is solved.
This has happened a couple times to me and the fix is fairly simple. The problem is the trash ram is pushing down on the edge of the metal of the trash compartment because the door is partially open. The solution is to back-up the ram the the door will close.
To back-up the ram, you will need to pull the compactor out from under your cabinets and unplug it. Turn the compactor on it's side to expose the bottom. There is a plate on the bottom that covers the motor gears. Remove the plate and turn the large gear counter-clockwise to back-up the ram screws (at least this is how it works on my model works). The gears are a little greasy so you may need to add some after messing with the gears.
Here is an assembly drawing of your compactor.. Please note item # 102 ( direction switch) ..That may be affecting the perfomance of your motor or your motor may have a dead spot on the windings.. Here is a link to a website for parts that coincide with this drawing.. There isn't an awful lot to a compactor in terms of hardware so good luck.. Hope this helps..
Sure is... The motor drives a ram up and down to compact your trash... Like most drive systems.. it needs to find a refrence position near the top of the stroke.. that position is normally sensed by a switch.. so it is possible your motor is bad or.. it is also possible your top sense switch is bad too.. For $400.. the GE tech should come out and stomp on your trash until it is compressed.... In either case.. if you are handy.. you may be able to open the compactor up ( with power unplugged) and check the position of the ram.. if it is near the top.. you may be ableto reposition it down a little then try cycling it.. It may buzz if the motor is bad ( windings shot) or it may work OK.. if it does and the problem comes back after you cycle it.. there is a good chance the top sense switch is bad or the windings in th emotor bad too.. Hope that helps...
Had a similar problem with mine. I took it apart and found that the nut that is on the bottom end of the ram screw was loose. I tightened it and it fixed the problem. That was about a month ago. Now it is doing it again. I'm going to tighten it again this weekend and apply Loc-tite to the threads.
To get to the nut, you have to lay the compactor on its side and remove the plate from the bottom. You'll see a chain that goes around the motor sprocket and both ram screws. You need to tighten the nuts on the ram screws.
