ApplianceWall Oven
What 9D42 is telling you
The oven is reporting a possible fault with its door latch assembly, with the door switch, or with the wiring that serves them. It is worded as a possibility only.
Owner steps, in order
Shut the breaker feeding the oven and let a minute pass.
Turn the breaker on to give the oven power again.
Keep watch for a minute: does 9D42 come back?
Confirm that the oven runs normally.
If the reset does not clear it
A returning 9D42 means it is time for a technician to look at the latch, the switch and the wiring.
