Customer Questions and Answers for Timer by Whirlpool

Sue, The motor hum, tells you the voltage is getting to the motor, but is the voltage correct, You could have a faulty contact in the timer, You could check for 110-120 VAC , on the blue wire at the timer to chassis ground, when you press the start button, with a multi meter. Your first check should be at the terminal block of the dryer on the back, make sure there are no loose connections there, and you have 240 VAC across the two outside terminals of the block(where the wires attach). You need to be careful, if you do live voltage tests. Good Luck and Thanks
