Customer Questions and Answers for Dryer Timer by Whirlpool

If what ever fell and broke the timer dial knob, was probably pretty heavy, chances are the timer shaft is bent or may have become out of alignment with the internal contacts of the timer. No it will not come with installation instructions, but it's not that hard a repair to perform. Unplug the power cord, remove the three or four screws across the back side of the control panel and "roll" it forward from the top. Remove the timer mounting screws, and reverse the procedure to install.
