Because of infrequent use, many users forget how to set the self-cleaning cycle and conclude that there is an oven failure. There are several steps involved. Electronic self-cleaner can be the least obvious of all. Properly set the timer. As mentioned, the most common problem centers around the latch assembly.
Many latches are only sheet metal and easily damaged.
The latch assembly includes up to three switches that monitor the latch arm position. Access to the latch usually requires removal of the oven from the cabinet. In a few cases, it can be accessed through the front grill or console. Many GE latches are mounted on the back of the oven and operated by long lever arms. Careful observation and testing of the latch switches will almost always locate the problem.
