Symptoms
- Can opener doesn't grip the can properly
- Cutting wheel spins but doesn't pierce or cut through the lid
- Motor runs but the can doesn't rotate
- Unit stalls partway around the can
Likely causes
- CommonDirty or corroded cutting wheel and gearFood residue buildup on the cutting wheel and drive gear prevents them from gripping and turning the can properly.
- CommonDull cutting wheelThe small piercing/cutting wheel wears down over time and eventually stops cutting cleanly.
- PossibleCan not seated correctly under the cutting mechanismMisalignment when loading the can prevents the wheel from engaging the lid edge.
- PossibleWorn drive gear or motorInternal gear teeth can wear down after years of use, causing slipping.
What to do
- Unplug the unit and thoroughly clean the cutting wheel, drive wheel, and surrounding area of food debris and rust.
- Check that the can is seated with the lid edge properly aligned under the cutting wheel before starting.
- Test with a couple of different cans to rule out an issue with one particular can's rim shape.
- Feel for resistance or grinding when manually rotating the mechanism by hand (unplugged) to check for a mechanical bind.
- Consider replacement if the cutting wheel is visibly dull or the gears are worn, since these parts usually aren't sold separately for most models.
Tools and parts
- Small brush
- Cloth
When to call a pro
Small appliance repair is rarely available or cost-effective for electric can openers; replacement is the usual solution if cleaning doesn't help.
