Customer Questions and Answers for Timer by Whirlpool

Hello Andres, First and most important, unplug the unit from its' power supply. Then remove the six screws holding the control panel back on and pull the knob off. Now it's really important not to remove the wires yet as you will do that one at a time as you install them on the new timer. You do this to prevent cross-wiring the timer and costing yourself time and money. Now there should be two 1/4 inch hex head screws holding the timer in position. With these removed, you will have enough slack in the wiring to hold the new timer next to it for "one wire at a time" wire replacement. Once all of the wires have been transferred to the new timer, reinstall the two 1/4 inch hex head screws and the knob. Reinstall the back panel cover and test the unit.
