TurboChef High-Speed Oven Message OVEN DOOR OPEN: Door Not Closed
OVEN DOOR OPEN on a TurboChef C3 oven means the cook door was opened during a cook cycle and not closed properly. Open the door, remove any food obstruction, then open and close the door several times. If it stays, call Customer Support.
Low: an operator prompt, usually cleared by closing the door properly.

What does TurboChef OVEN DOOR OPEN mean?
Microwave and convection cooking are only allowed while the cook door is closed and latched, so the control watches the door switches during a cycle. If the door is opened and then not closed properly, the control shows OVEN DOOR OPEN and stops cooking. The i5 owner's manual also shows Oven Door Open with an alarm. The manual lists three causes: a food obstruction, a door that is still open, and door switches that are out of alignment. The first two are what an operator can fix: a tray handle, food or packaging stuck in the opening, or a door left ajar. The third needs a technician. Opening and closing the door several times seats the latch and lets the switches register, which the manual gives as the step to try.
