What could cause a 240v dryer outlet to have proper voltage but not power the dryer?
I recently had a problem that stumped me. My dryer had worked for a couple of years and then stopped heating. Turns out, the 240 receptacle had a bad contact on one of the 120 legs so it made poor contact with the plug. I replaced the receptacle. Later, I autopsied the old receptacle, cutting it open by drilling out the central rivet, and found that one of the spring clips had actually broken, so it didn't maintain tension. Of course when I had probed the receptacle I had been able to get the 120 because I was hunting for it. Perhaps your receptacle is bad?
