Customer Questions and Answers for Timer by Whirlpool

Ray, No there is no special tool needed, just a small flat blade screwdriver. You will need to access the backside of the timer assembly, by removing the metal control console back panel. In the larger opening on the left side of the timer back, you should notice a "D" shapeed insert, You will insert the screwdriver blade into the flat area and carefully pry out on the insert(approximately 3/8 to 1/2 inch, and pull out on the timer dial knob at the same time. Reverse the process to install the knob on the new timer. Good Luck and Thanks
