Plain language
What this code means
These codes may indicate a problem with the oven door latch assembly, the door switch, or associated wiring.
When the display of a JennAir range or wall oven reads 4D or 9D followed by digits, the manufacturer is pointing at the door. Seventeen codes carry one identical line: the trouble may lie in the oven door latch assembly, in the door switch, or in the wiring tied to them.

Parts involved
Hardware that catches the door and keeps it shut makes up the latch assembly. As for the switch, it lets the control learn if the door is closed. Because the control relies on both, they are named with the wiring, and no narrower answer is given.
What an owner can do
Open the breaker that powers the oven.
After sixty seconds, close it again.
Keep watching the display for a minute in case the code returns.
Check the oven still works.
What should be left alone
Nothing in the page covers bending the door into line or pulling off the latch, so do not try either.
Why so many numbers?
JennAir writes the very same sentence for all seventeen and offers no key to the numbering.
