Why it stopped
Power at the switch, the reset button, the breaker and a manual turn of the plate. A jam that clears and a motor that will not run again are two different outcomes, and you hear which one you have.
A disposal that hums, trips out or drips into the cabinet is a small job that turns into a wet one if it is left. Emergency Plumber Chandler works out whether the unit can be freed and resealed or has reached the end, and prices both before touching anything.
Before anything else: never put a hand into the grinding chamber. Switch the unit off at the wall and at the breaker first, and use the hex key slot underneath rather than reaching in. A hum almost always means the motor has power but the plate is jammed, while silence usually means the internal overload has tripped or the wiring, switch or unit has failed.

Most of these calls are decided in the first few minutes. Emergency Plumber Chandler checks the cheap causes before quoting anything larger.

Leaks come from three places: the sink flange at the top, the dishwasher inlet on the side, or the discharge gasket at the elbow. Each is a seal or a fitting. Water coming from the body of the unit itself is not repairable.
You get both numbers before a decision is made, along with what the drain below the unit looks like, since an old trap arm often explains why the sink was slow in the first place.
Freeing a jam, replacing a splash guard, resealing a flange or swapping a leaking discharge gasket are all straightforward. A seized motor, a cracked housing or a unit that trips the breaker every time is a replacement, and on a disposal that has been grinding hard Valley water and scale for a decade or more that is often the sensible call anyway. Keep the model details if you have them, because a like-for-like swap is simpler than changing the mounting.
What goes in matters more than the brand. Fibrous and stringy waste wraps the plate, coffee grounds and rice pack the trap, and grease that pours in warm sets solid a few feet down the line. Citrus peel is fine in small amounts but will not clean anything. Run cold water before, during and for a good while after, and scrape plates into the trash first.
If the sink still drains slowly once the unit runs properly, the clog is further along and needs drain cleaning. If other fixtures are backing up at the same time, that points at the main line and sewer line repair. A weeping shutoff valve under the same cabinet is a fixture repair, and standing water you cannot account for is worth a leak detection visit. Kitchens in Gilbert and across the southeast Valley get the same service; see all plumbing services or tell us what the unit is doing.
Something is wedged between the plate and the grind ring, so the motor has power but cannot move. Turn the unit off at the wall and the breaker before anything else. A plumber frees it from below and checks whether the motor survived the stall.
Jams, seals, splash guards and the mounting are worth repairing. A failed motor, a body that leaks or a unit that keeps tripping is not, especially on an older one. Emergency Plumber Chandler quotes both so the choice is yours rather than a surprise on the invoice.
Grease and cooking oil, coffee grounds, rice and pasta, fibrous vegetable skins, bones and anything that swells in water. Chemical drain cleaners do not belong in one either, and they make the plumber's job at the trap harder and less safe.
Maybe, but the supply shutoffs, the faucet tailpieces, the trap and the dishwasher hose all live in the same cabinet. Dry everything, run water for a minute and watch where the first drop appears. If you cannot tell, say so when you call and it gets checked as a group.
