How can I remove a broken knife blade stuck in my sink disposal?

There should be a hole in the center of the bottom of the disposal. A 1/4" allen wrench fits in there so you can spin the insides and loosen stuff stuck in there. You might also be able to jar ...

Dishwasher plug blocking disposal outlet

Re-wire the outlet so the top one is on the switch instead of the bottom one. Is this even possible, and if so, considering I've never done it before and it's under the kitchen sink without much room, ...

Electrical line has no juice after being shortened

Usually there is a switch before the disposal. You push a button, or flip a switch to turn on the disposal. Did you turn the switch on? If this is the case, then this was not the best option for this ...

Garbage disposal has strange switch wiring

The black wire is actually connected to the red wire next to it by means of a backstab. It's a good practice not to use backstabs because they are prone to failures. Twist the switch off that black ...

Garbage disposal on/off switch trips the circuit breaker when turned on

First, since you are working on a rental unit, condo or multi-unit building, only a pro electrician can do the necessary wiring changes. Most AHJs will waive this for simple things like a dishwasher ...

I installed some wire nuts, but they push back on the cover when closed

Consider using UL-listed lever nuts such as Wago 221s. IMO they are much better for DIY homeowners than traditional wire nuts. To address your main concern, that you have limited space in the small ...

Is it a problem that my sink disposal has exposed wire nut connections in the cabinet?

Wiring dishwasher and garbage disposal

The 12/3 and 20A is perfectly fine. This is a Multi-Wire Branch Circuit or MWBC. The basic idea is that by having two breakers on opposite legs (240V between them), you get 2 x 120V using 3 wires (hot/...

Can I wire a switch to toggle between the top and bottom outlets of a 1 gang receptacle

Crazy but in a good way. Brilliant actually. Use any common 3-way switch, I don't see a problem with it. The only issue that might call for a 2-gang switch box is the need for GFCI protection on both ...

That should be a slip fit and simply pull out. It's possible that some prior worker glued the joint between 1&2 with 3 inserted, and it got stuck that way. It's also possible that it's merely ...

Garbage disposal not working: It hums, but the blade spins freely and reset button is not staying engaged

If the unit is not jammed, as you say and the unit hums but does not run, it needs to be replaced. There is nothing reparable inside these units. You need a new one.

NM cable from wall box to dishwaster

You should not run NM sheathed cable through a cabinet that has doors which open to allow storage. You should be installing grounded receptacles and using appliance connector cords.
