How to Troubleshoot a Timer Switch on a Maytag LAT9593AAL

The Maytag LAT9593AAL is a top-load washing machine with a cycle control knob on the front panel connected to a timer switch inside the control console. The part regulates the different wash cycles by sending signals to the various washer components for pumping out the water, engaging the transmission for the spin and agitation cycles, and refilling the tub with water. If the timer switch malfunctions, the Maytag may not advance properly through a cycle. Troubleshooting the part takes relatively little time.

  Set the mutimeter to test for ohms. Touch the two probes on the multimeter to each pair of terminals on the timer switch, one pair at a time. You are testing the terminals that control individual steps in the wash cycle, such as fill, wash, spin and rinse. The display on the tester should register zero for each pair of terminals. Any other reading means the timer switch on the Maytag LAT9593AAL is defective.
