Flex Clean self cleaner error - kenmore elite gas cook top
We have a Kenmore Elite 5 burner gas stove. After wiping out the crumbs inside the oven, we turned on the Flex Cleaner self cleaner. The oven door would not lock and then we received an error code F93. We shut it off and tried it again. We received th same error code. We then tried turning on the oven and recieved a different error code, F90...we can not use the oven at all at this point. Please advise what this error code means and how do we fix it?? Thank you!
