Replace or repair? Checking out a faulty disposal

DWIGHT BARNETTScripps Howard News Service

A reader contacted me about a garbage disposal that is running, but not working. The flywheel is moving freely, and the reset button is in. There is power to the unit, but when it is turned on, all it does is hum.The reader’s question: What do I do now? To explain, the humming sound is the motor’s electrical rotor, which is supposed to turn inside the magnetic housing of the disposal. The rotor is attached to the cutting blades of the flywheel and is supposed to be turning at a high revolution. The humming could be the electrical noise caused by a stuck rotor that is not turning. This will eventually trip the reset button on the bottom of the disposal. Free the stuck flywheel using a wooden spoon or broom handle. If the rotor is turning and the flywheel is not, then the flywheel is broken and needs to be replaced. All appliances age and will reach a point where it may be economical to simply replace the unit rather than try to make expensive repairs. The point at which replacement becomes economically viable rests solely with each person and his pocketbook.Dwight Barnett is a certified master inspector with the American Society of Home Inspectors.
