DIY
Flip the switch and get nothing -- no hum, no sound? That is electrical, not a jam. Tripped reset, tripped breaker, or bad switch are all quick fixes. Burned-out motor means replacement.
Tools:
Flashlight
Non-contact voltage tester
Screwdriver (flat and Phillips, for switch plate and wire terminals)
Multimeter (optional, for testing switch continuity)
Replacement wall switch (if switch is faulty, $2-5)
Disposal Jammed
medium
DIY
Motor hums but nothing grinds? Something is wedged between the impeller and shred ring. Ten-minute fix with a 1/4-inch Allen wrench.
Tools:
1/4-inch Allen wrench (usually included with the disposal unit)
Flashlight
Tongs or needle-nose pliers (for removing debris)
Wooden broom handle (alternative to Allen wrench)
Ice cubes and rock salt (for post-jam cleaning)
Disposal Leaking

Disposal leaks come from three places: top (sink flange), side (discharge pipe or dishwasher hose), or bottom (internal seal failure). Where it leaks tells you whether it is a simple fix or a replacement.
Tools:
Adjustable wrench
Screwdriver (flat and Phillips)
Plumber's putty
Disposal wrench (or use a screwdriver on the mounting lugs)
Replacement discharge pipe gasket
Hose clamp (if dishwasher connection is loose)
Flashlight
Bucket and towels
