Customer Question

Hello Mike,
I have older home with a old 3 prong dryer, I junked the old dryer and moved a newer used 4 prong dryer that was working that day from the neighbors house.
I removed the 3 prong outlet, and installed a new 4 prong outlet into the wall at are house.
The wires coming from inside the wall are green black and white,
The post on the new outlet are 2 copper bolts 1 green and 1 silver.
I coneted the black and white to there there own copper bolt and the green to the green bolt and left the silver bolt empty.
I flipped on the main breaker and nothing, so I tested the outlet got 240v
Then I opened back of dryer and tested dryer cord bolts. With 1 end of my volt meter on green each leg (black red and white) on dryer cored reads 120.
Testing any two at same time gets me my 240 (red & black - red & white - black & white)
Any ideas on why my dryer is not turning on.
Thanks Manda

Hi, I'm Mike G and I'll be assisting you. The direction you received saying to install a 4 wire receptacle on a 3 wire circuit was wrong. The only thing required was to install a 3 wire cord set on the dryer and connect the ground and neutral together in the dryer.

The dryer cdepends on the neutral for operation of controls and the ground for safety. Your neutral isn't connected and no doubt why it's not working.
