ELECTRIC DRYER!!! I waited a day and plugged the dryer back in then reset the breaker and it immediately popped off again. I waited 2 more days, same thing. I took the top back off and saw a black mark where the oil dripped down a wire. I cleaned the oil off and painted on the burn, but it still pops off! I need to take the bottom back off and clean the oil and see,,,,!!!?I don't know what to look for?!!! Plus, I don't know what to do when I find something! HELP PLEASE!!!
