How to fix it
Work through these in order, the most common causes come first.
Start With the Basics
Clear the visible blockage: Power off the feeder first, then check the chute for a lodged piece of kibble.
Never force the auger to keep turning against a blockage, that's how gears wear out prematurely.
Check the kibble itself: Jams that started right after a food switch usually point to the new kibble's size or shape, not a mechanical problem.
Look for clumping: Kibble stuck together from humidity jams far more easily than dry, loose pieces.
Diagnosing Your Specific Problem
Motor runs but nothing dispenses: almost always a physical blockage in the chute or auger.
Power off and clear it by hand.
Jams started after switching food brands: kibble size or shape mismatch.
Compare the new kibble's dimensions against the manufacturer's recommended range.
Jams happen more in summer or humid rooms: moisture-related clumping.

FAQ
Common questions
Why does my feeder jam only with certa in bags of food?
Kibble shape and size vary between brands and even between bags of the same brand. Larger or irregularly shaped pieces are more likely to wedge in an auger's chute than small, uniform kibble, so a jam that appears after switching food is usually about the new kibble's shape, not a mechanical fault.
Is it normal to hear the motor running but no food comes out?
That's the clearest sign of a physical jam, usually a piece of kibble lodged in the auger or chute. The motor is trying to turn against the blockage. Unplug or power off the unit before attempting to clear it by hand.
Can humidity cause jamming?
Kibble exposed to humid air can absorb moisture and clump together, especially in a hopper that isn't fully sealed. Clumped kibble is far more likely to jam an auger than dry, loose pieces, which is why storage location matters as much as the feeder itself.
How often should I clean the auger or chute to prevent jams?
Every 2 to 4 weeks for most households, more often in humid climates or with oily kibble that leaves residue. A quick brush-out of the chute and auger threads removes the small buildup that eventually causes a jam.
