Customer Questions and Answers for Dryer Electronic Timer by Whirlpool

Hello LR. WP33001730 is the correct timer for your serial number. These are not bad to change. Disconnect the power to the unit. Remove the back panel of the control panel. Then remove the knob and the screws holding the timer in place. Put the wires off the old timer onto the correct terminals on the new timer. Reinstall in reverse order. Hope this helps.
