Tried to use cleaning cycle for lower oven(did upper oven yesterday just fine!), but the cycle started and then shut down after about a minute. The display for cleaning was normal until shutdown leaving error codes E7/F5. while the cycle was attempting to start, I could hear a relay continually set then reset at about three second intervals. Now the door latch will not allow access to the lower oven although normal operation of the oven appears possible
