Question: I have a stackable washer dryer combo. The dryer works on 240V and the washer works 120V, but they have 1 control panel. I don't have 240V in my new apartment, and am hoping to have the power cord switched to a 120V. 
I have read that this process involves: 

* getting a 3 wire 120 cord-set of at least 14 gauge and a 14 gauge jumper wire.
* connect neutral to neutral terminal
* black to black terminal
* ground to ground terminal
* and jumper wire from neutral to red

I have no experience with electronics and don`t plan on doing this myself, I had an electrician come look at it for me but he has never done it before, my question is:

Does this look correct, can he or (most likely another electrician) do this? 
I know it won't be code, I just need to know if it's possible.

Answer: 
1. Some dryers do have the ability to run on either 110v or 220v. Bear in mind that 110v gives it roughly the same power as a hair dryer, so even if this were possible, I wouldn't recommend it, as it can take 2 hours for the clothes to dry.
2. Assuming that your apartment has 220v service at the panel, if you can find two outlets on opposite legs (i.e. 180 degrees out of phase) there is a commercial product that will give you a 220v outlet, which you could plug your dryer into. YMMV.

This will give you an appliance with one dead side. Assuming the motor and electronics are on the black phase, your dryer will run at one-half of the stated power - essentially on 'low' all the time.

The good news is while it will take twice as long, it's only using half the power to the total cost to dry your stuff is the same.

Do you have an exhaust vent for the dryer? Washers can go in any closet with water and drain, dryers need a vent to the outside. No, another room or the hallway won't work. Yes, a connection to the bathroom vent will work IF other units have one-way valves in the vents. Otherwise you will pump your (slightly) warm, moist air into their space.

And of course something that blows air out must have a way to draw air in.
