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

Replace door switches primary and secondary. 

Lid switch problem. Easy to fix, not so easy to diagnose. First thing to look at if something goes wrong and there does not appear to overtly be mechanical issue like pump, etc. 

First I checked the continuity of the lid check switch. I found a video for that on You Tube. The lid check swithch was OK. So from looking at some You Tube videos and comments on Appliance Parts Pros it seemed like it must be the timer. So I ordered a new timer and also a new lid check switch since that was an inexpensive part. There was no video on Appliance Parts Pros for my model number on how to replace the timer. I found something somewhat close on You Tube. It was quite easy. To take the timer control knob off I used a small screw driver to pry off the center cap, Then I used the small screwdriver to pry off the circlip that was on the timer shaft. Then there were just to screw to remove on each side of the timer shaft which I used a nut driver for. Then I pulled off the wire harness from the timer. Note that there is a catch on the bottom of this harness that is not easily seen that needs to be pulled out of the way to remove the harness. There is also a catch on the top but that one is easily seen and real obvious. Then it is just a matter of going in reverse to in stall the new timer. There is a ral good video on AppliancePros Parts.com on how to replace the lid check switch. 

So, I came home from work and my partner informed me that the washing machine was agitating and then suddenly it stopped. So I opened the front face of the washing machine and found the schematic and rang out the switches, determined that the lid check switch had failed but the lid switch was still fine. Ordered the switch and all is well. The switch came Saturday and I installed the switch in the early evening, closed the lid and the washing machine still didn't work. Early Sunday morning I tackled the issue again, this time I rang the entire circuit from power in, to the timer, pressure switch, and motor. Everything rang out, so I reassemble the washing machine and it WOULD NOT START! So I began opening and closing the door and realized that although the lid switch was fine, it had worn just enough plastic off of the button so that the arm didn't fully depress the switch when the door was closed. So for the 3rd time, I pulled the switch housing and dabbed about 1/4'' of super glue over the button of the switch so that the arm would make contact with it when the door was closed. Lesson learned, just because the switch rings out, doesn't mean it is functional. Due to my own error, a 15-minute job turned into a day and a half. But I know that the remainder of the circuit and parts are in good shape! 

I used jumpers to connect the three connections on the water pressure switch and determined that this was my problem. I also found that my Lid Check Switch was also bad. I called the local parts store and was told that it would take 7-8 days to get the parts. I was also told that the Lid Check Switch had to be ordered as an assembly, which doubled the price. I decided to check the internet and found AppliancePartsPros.com. They had the Lid Check Switch (didn't need the whole assembly) and the Water Pressure Switch in stock and shipped them the next day. It still took 8 days to get the parts, but the parts were cheaper and just as good (I didn't use priority shipping). When the parts arrived it took me less than ten minutes to install them, and my washers works good again. 

I bought the lid switch and replaced it. very easy to replace. This was the problem. 

After some research and some testing with a multimeter, it turned out the lid check switch was bad. Instead of purchasing the entire switch assembly, I purchased just the switch that was bad. The lid switch assembly is easy to disassemble, but requires removing the spring loaded lever to remove the lid cover switch. This is wall current, so make sure you unplug! Installed, test, and everything... still didn't work. When the switch fails it takes the fuse out with it. Since I hadn't ordered the switch assembly w/ fuse, I didn't have a fuse. Trundled myself off Fry's and picked up a pack of fuses ( 1 amp, 120v/230v. ~$4 for 5 of them). Replaced the fuse, and immediately blew one when testing the switches by pressing them in a bad combination. Replaced the fuse again, reassembled, and everything works fine. Clean clothes again! The whole project took perhaps 1-2 hours, including the time to research, disassemble, troubleshoot and reassemble.
