Disposal hums without grinding
Possible causes. A jammed mechanism can hold the motor stationary. Continued humming may overheat the motor; it does not establish whether the disposal can be repaired.
What the technician checks. With power safely isolated, the technician checks the grinding mechanism, reset protection and motor condition. Plumbing connections are inspected for contributing drainage problems.
Typical repair. The obstruction may be cleared professionally or a failed unit may require replacement. Never keep cycling a stalled motor or put a hand into the grinding chamber.
First-visit outlook. The model, safe access and required parts determine the visit scope. We explain the findings and quote before work; completion on the first visit is not guaranteed.
