The sliding metal tracks on the pull out garbage bin inside the kitchen cabinet jammed completely solid this morning, leaving the trash drawer stuck halfway open right in the middle of the walkway. I thought it would just be a case of spraying a bit of lubricant on the steel rails or pulling out a rogue piece of plastic stuck in the gears. Instead, I spent an hour crammed on my side inside a greasy cabinet fighting against warped ball bearings.
The whole mounting frame was completely bent out of alignment from people pushing down too hard on the trash bags over the last year. The tiny steel balls inside the tracking rail had slipped out of their plastic casing, completely locking the wheels from sliding back or forth. I had to unscrew the heavy metal tracking directly from the cabinet floor base just to force the jammed drawer unit out of the cupboard, which spilled a bunch of old coffee grounds all over the wood panels.
Trying to hammer the bent aluminum rails straight with a rubber mallet on the floor took way too many adjustments. If the track width is off by even a millimeter, the drawer carriage will wobble and get stuck all over again when you try to slide it in. I ended up having to pack two small cardboard shims under the left mounting bracket just to keep the tracks running perfectly parallel against each other.
The trash bin carriage slides back and forth inside the cabinet smoothly now without catching on the frame molding or making that loud metal grinding sound. The automatic cabinet door latch aligns with the catch plate properly when you kick it shut. The pull out drawer is fully operational now.
