How to Troubleshoot & Replace Whirlpool AP6005728 / WP207166 Lid Check Switch

Replaced lid control switch 

The schematic was located inside the head of our old Maytag washing machine and showed the current flow path was through the lid switch, and then the smaller check switch mounted just in front of it. With the AC power unplugged, the fuse and both switches were checked with an ohm meter for continuity. I found an open circuit in the "lid check switch". Having the schematic information allowed me to make a simple by-pass wire for testing purposes only, and the machine came back to life. Replacing the switch was very easy, secured by one screw, and then transfer the three wires over to the new switch. To access this switch, the head tilts forward by removing the two inboard screws visible on the top. This opens it up and gives you all the access you need. Good luck. 

Based on a website recommendation that the lid switch is often the problem I used the appliancepartspro.com part number search to find my model and the correct part number to order. Another website told me how to remove the old switch and replace it with the new one. It would have been nice to have information about how to troubleshoot the problem. 

Got to your site. saw a video, tested the part and diagnosed the problem. Ordered the part and problem solved. best part, the part was at my house the day after I ordered it. Thank you 

Hard to tell it was the lid switch. There were dual switches wired in tandem so a simple test was not possible. There was no physical damage on visual inspection, switches sounded healthy when the lid was moved, there were no mechanical disconnects or breaks. I prodded the connections with a screwdriver and found that the slightest movement of the switch would allow the washer to operate for the remainder of the cycle. Replacing the switch was easy, the accompanying youtube video eliminated any unknowns. $30 total repair + ~1 hour troubleshooting before the actual 20 min repair. 

Researched Troubleshooting section of appliance manual. Ordered part. Works fine. 

Bought a new check switch, and cleaned the contacts on the relay. The relay was not an available part, but it was repairable.
