LATCH Assembly WB10X29077

When first plugged in, and bake is engaged, the oven clicks and begins to preheat. In about a minute, the bake shuts off, with no error code. When attempting to select bake or any of the buttons associated with bake, there is a little double beep, and nothing happens. It is completely disengaged. I tested the high limit switch, and it is bad. I then replaced it, but it continues to do the same. My guess is that it has to do with the cooling fan, but without an error code, I'm sort of just guessing. Any help?
