GC900QPPB0 Whirlpool Trash Compactor - Instructions

Same problem as described previously on this site. Pulled unit out and replaced the gear as described. Thanks for the info - would have been tough with out it.

Very simple, changed the gear, adjusted the drive and tested. Very straight forward.

The repair was a breeze, a piece of cake, a walk in the park, a day at the beach. The part arrived quickly and installation was fast and simple. A week earlier I had the misfortune of ordering these parts from another supplier. One of the parts obviously was not correct, so I called customer service. Although the operator was polite, she insisted that the part I received was the right one (even though it was 2 inches too narrow). I looked up the part at PartSelect.com and ordered it. It arrived the following day, and fit perfectly. Thanks, PartSelect.com.

I got the model number. Went to partselect nad found picture.Got part number. Ordered part and recieved next day. Opened drawer and removed old handle (2 screws ) and installed new part.Closed draw. DONE

Followed PartsSelect instructions, the Compactor was appoximately $1000. when I purchased it. The kit was $26.14. I will forever be a customer of this company. Thank you, Brian

Laid appliance on side - removed top sheet metal cover and bottom sheet metal cover. Broken delrin ring gear was on bottom of bottom cover (housing). Gear had broken off of its hub, which also was the sprocket chain drive for both acme screws driving the compactor platten. Motor had to be loosened so that the chain could be removed from the old sprocket hub, and the new delrin ring gear - with new sprocket hub attached - could be mounted on its fixed spindle. With new delrin gear/chain sprocket mounted, the motor had to be spaced and tightened to allow 0.010 inch lash between the gears. The only instructions included with the new gear was how to do this - by placing a piece of paper in between the pinion gear on the motor, and the new ring gear, and then tightening the motor into place. This was done, the sheet metal covers were re-installed, and the compactor works just fine. There is a design flaw in the original (KitchenAid) engineering of the gear, however, and I expect that in the next four years this will probably happen again.

Thanks to Parts Select and their detailed instructions it turn out great! Replacement Parts fit Great!

First off....I was surprised at how inexpensive the drive gear kit was. As others commented, they fit perfectly and I believe will fit other manufacturer's models since there is a lot of cross branding. The Drive gear replacement itself would be easy as described by others so I won't repeat that. However replacing the plastic tubular "ram stops" on the screw drive was a challenge since there are no "helpful hints" in the blog. To do that you have to work from the top and sides. Needed to remove the two gear cams where the screw drives are seated on the bottom of the unit, then (working with the unit on it's side)you have to raise the whole (heavy) plunger that is attached to the drive screws high enough to remove the old tubular ram stops and bushing and replace. To raise the plunger assembly out from the top you have to remove the sheet metal top plate of the unit....and....importantly remove the control panel on the front where the switches are. There is a limiter switch that has a metal arm which engages a plate on the plunger to stop the unit when it reaches the top. You need to remove that switch to be able to raise the plunger assembly high enough to get the new parts on the screw drive. Put all that back together and then go on to the gear replacement as described by others which was straight forward. Very messy job with all the grease and garbage residue. I am pretty handy figuring these things out, and there may be an easier way, but next time I will call a pro or replace the whole compactor.

Removed unit, put in new one.

I removed the unit from under the kitchen counter by first pulling the trash drawer all the way out and lifting it out of the track and setting it out on the floor. I then slowly pulled the compacting unit out and unplugged the cord from the electrical outlet. With the entire unit out in the floor I took a nut driver and removed the screws from the top plate and the screws from both sides at the bottom of the front housing. This allowed access to the directional switch. Two screws on the right side of the switch have to be removed to remove the switch along with two holding plates on the left side of the switch. The switch can then be accesses for removal. Several wires are attached to the switch and should be removed one at a time and installed to the identical identical location on the new switch. The new switch can then be installed by aligning the holes and reinstalling the holding plates. When this is done the front frame and top plate can be replaced with the nut screws. Plug back into the electrical outlet and see if it works. In this case it did exactly what it was doing before I started. So either I did not reinstall the directional switch properly or I am in the one percent rather than the 99 percent that should successfully solve the problem as suggested in the trouble shooting guide. I will now recheck the installation of the directional switch nd then check the bottom of the unit to see if the gears or chain drive are broken .

took longer to pull it out and put it backunder the counter then to pull the panel take the chane gear & drive gear off and put it back together

easy ... got the new bag holder and replaced old one. the impressive part of the process is how easy it was to get the part info from partselect website. could have spun my wheels a lot without that.

A trash compactor is a very simple machine. Basically there are two parts that could cause the problem of the machine not shutting off at the end of the cycle. The limit switch which was listed as the most likely cause and the momentary contact switch, if fused would cause the same problem. I first replaced the limit switch and to my dismay, the problem continued which meant the contact switch was at fault. The switch unit is easy to get too, First remove the two screws securing the front panel to the machine. Then transfer the wires from the old switch to the new. Remove two screws which secure the switch unit to the front and discard the old switch. Reassemble the unit in the reverse order and plug the unit back into the wall. Works perfectly!

removed old handle by removing screws - installed new handle by inserting screws in same in same location as those removed

take 2 screws out on top cover with key switch. remove two screw holding directional switch. remove wires, one at a time, and place on the new switch. put new switch in place with two screws. put front cover on with two screws and test. works like a charm.
