I think my new stove cord was installed wrong and after being plugged in we heard a ((whooooaamp)) sound and all the lights in the house flickered, now none of my 220 appliances will work correctly. The other appliances weren't plugged in when this happened, except the water heater which I cant get to turn on either. the time and displays on my stove come on but the stove top & oven wont do anything, my dryer displays come on, but when I push the start cycle button the display flickers and then everything shuts off, as if everything isn't getting enough power to fully work. what could have happened? and what can I do now??
