I have a frigidaire dryer that is displaying all the same symptoms that would indicate the thermal limiter needs replacing, but when I tested the thermal limiter with my volt meter, is zeroed out like it is supposed to. Is it possible that the volt meter was reading wrong? I haven't heard of another cause for the same symptoms. The drum is free, motor is free, but when I hit start, nothing moves. I just get the little starter hum. Any ideas? Can I test the motor?
