How to Troubleshoot & Replace Ge AP3203787 / WD21X10169 Door Interlock Switch Assembly

Opened up the control panel. Door interlock had one of the two micro-switch’s broken. Wired the conductors together temporarily until the new one arrived. Also ordered a couple of extra micro switches in case it happened again. Lone KW3A normally closed switch. Replaced and reconnected wires. Working fine. 

Replaced the interlock door switch, I also replaced handle actuator and spring as well. 

Replaced the interlock door switch. 

Went to your website, found the part, ordered it had it in 3 days and it was installed 20 minutes later. Great service. Thanks a bunch. 

The video provided by Appliance Parts Pros is excellent! I followed its steps. The one problem I had was getting the ribbon to disconnect. The plastic pieces that hold it together are fragile and broke. So, instead of disconnecting the ribbon I placed a kitchen stool in front of the dishwasher door and laid the top portion on it. Then I was able to remove the handle and change out the actuator. The handle was fine and did not need replacing; a tab on the actuator had broken. (In my opinion the actuator should be metal instead of plastic. The dishwasher is less than 2 years in service). // While I had the door apart I also replaced the Interlock Door Switch. The last load we had run resulted in plates with baked on food residue. It seemed that the problem we had matched the description that points to failure of the switch. However, we later observed that the soap dispenser was caked shut and had not opened. 

Replaced the interlock door switch. Fifteen minutes and it was working as good as new.
