Knowing how to repair a timer on a washing machine will save money and frustration. Fortunately for the do-it-yourself homeowner, the timer is quite accessible. The homeowner will need the owners’ manual for their particular model of washing machine. The Maytag washer (used as an example here) is similar to most other brands, however there may be variances in how the control panel is removed.
Disconnect the power to the washing machine either by unplugging it or turning the circuit breaker off. Place a sheet over the top of the washing machine to prevent damage to the finish.
Remove the timer knob from the control panel by pulling it off the shaft with your fingers.
Remove the screws that connect the front of the control panel to the back of the panel using a screwdriver. Rotate the front control panel forward, revealing the switches and wiring inside.
Remove the screws that hold the timer to the control panel, using a screwdriver. Disconnect the wiring harness to the timer by pressing in on the plastic tab and pulling it apart.
Press the plastic mounting tab at the bottom of the timer down to release the timer from the control panel. Insert the new timer on the control panel by snapping the plastic mounting tab into place.
Connect the wiring harness by pushing it into place on the timer until it snaps in. Attach the mounting screws with a screwdriver.
Turn the front control panel back over and reconnect it to the rear by attaching the screws. Slide the timer control knob back onto the timer shaft.
Reconnect the power to the washing machine.
