I have a Frigidaire front load dryer that will not come on. I had the drum belt replaced in it and prior to the belt going bad, the dryer worked just fine. A family friend replaced the belt for me and when he plugged it into the wall and pushed the start button, NOTHING! He mentioned to me that I had a 3 prong cord for a 4-prong socket but it's worked that way all the time. Could this be my problem or could something else be happening?
