can i use an electric stackable w/d to electric/gas connector?

I asked my Better Half--who is much smarter than I--and She didn't know either, at first, what a w/d unit is 'til I revealed it as Whirlpool, whereupon she responded, "washer/drier!"

Not familiar with w/d's myself but some 115-v homes are actually 2-phase, 230 v, determined with voltmeter connected between "hot" terminal of two 115-v outlets. However you have to be sure that the ground floats. Ask any tech buddy, he'll explain

Get a professional to take care of it so you don't ruin the machine and/or burn the house down.

In order to use the new w/d unit you would need to have a 30 amp 120/240v dryer circuit installed. Your 120 volt circuit will not work and the conductor size is too small to convert the circuit for the new w/d. Contact an electrical contractor, the new circuit should be an easy install.
