I bought a front loading washing machine (Samsung, J845) that was missing it's interlock door switch, so I bought a new one. I'm sure I've got it wired correctly, but can only get it to work if I manually engage the switch. Can anyone explain how the switch is supposed to work.
I can't for the life of me figure out how it's supposed to complete the circuit with just the door being closed and thus start the rinse cycle.
Here's the switch in it's default position. Just as if the door was open, the sliding bar obviously blocks the red pin (see below) from engaging/making contact.
Here's the switch when the door is closed. I would expect when I manually slide the bar (as pictured) that the red pin will engage (move towards the camera?) however it doesn't, thus it doesn't "engage" automatically.
If I flip the switch over and manually push it down, thus making contact internally, then the washing machine works! But I have to manually hold it from the backside.
What am I missing here? What is supposed to make the red pin engage? When the door is closed, is the red pin supposed to move by itself by electric force? or something?
Here's a picture of the switch's internals if it's relevant.
