Product review (2 stars): Seems like it's the wrong part for my model.
My situation was similar to other reviews. I ordered this to replace the door lock on an LG TROMM WM2277HW washing machine. The part was shipped quickly, but I noticed upon unpacking that the part was not the same size and looked different. The actual latch also appears to be plastic unlike the metal original. I gave it a try anyway since the plug fit and it fit right into place. It immediately latched when I turned the washer on and clicked a few times, then I got an error on the screen (can't remember what it was, I think PF? Something about a power fault). My old latch worked almost all the time but had stuck latched a couple times. I put the old one back on and there were no issues. Seems to be the wrong part even though it says it is compatible, either that or something was faulty. I gave a second star because it shipped quickly and there was no hassle on the return.
