Just reporting back with my experience replacing the lid sensor/latch on the Kenmore (Frigidaire-built) stack washer. It was actually a very easy job, and here's how I did it:
Remove the 2 screws at the bottom of the front panel on the washer, the panel then slides down and pulls off. Next, you remove the washer top which has the lid and lid sensor mounted to it. In order to do that, locate the philips-head screws close to the front underneath the top panel, one on the left and one on the right. Once those screws are removed, the whole top panel including the lid switch can be removed from the machine. (just make sure to unplug the wires to the switch, there's a total of 4. 2 go to the microswitch on the left, the other 2 are in a harness together that pulls off the right side of the switch assembly) With the top panel removed, replacing the switch/latch assembly is a piece of cake, just 2 screws holding it to the panel. Re-assembly is just the reverse of the steps I wrote above. I thought this job might be a bit involved, but I had it done in 20 minutes or so.
Thanks for all the help!
