garbage disposal will not turn off

[homewrecker]

Please help! Last night, the garbage disposal mysteriously turned on by itself and now we cant turn it off except by unplugging it. The outlet actually is a bit blackened at the connections which makes me think that the wiring to the switch may have been affected. But would that cause the electricity to be always on? I plugged something else into that same socket and it too could not be turned off by the switch. Is the problem with the switch or the outlet itself or the wiring between the two? Anybody see this happen before and know why it would suddenly happen? (Note that the dishwasher was running when this happened and is plugged into the bottom socket on the same outlet). Thanks!

Probably the switch was not "T" rated and the contacts burnt in the closed position. Get another switch.
