00:00Welcome to No Filler Fixes. So your Ninja Air Fryer Pro is showing an E4 error code indicating
00:06the door isn't securely closed? Let's fix it right away. No filler. First, check if the door
00:13is properly aligned and fully closed. Sometimes the latch may not engage correctly due to
00:18misalignment. Open the door completely, then firmly close it until you hear a click. Next,
00:25inspect the door sensor for any obstructions or damage. Food particles or grease buildup can
00:30interfere with the sensor's ability to detect whether the door is closed. Clean around the
00:35sensor area using a soft brush or cloth. After that, reset your Ninja Air Fryer Pro by unplugging
00:42it for 5 to 10 minutes. This clears temporary glitches and resets the internal systems.
00:49Plug it back in and test if the E4 error reappears. If the problem persists, examine
00:54the wires connected to the door switch. A loose or damaged wire could prevent the system from
01:00recognizing that the door is closed. Refer to your user manual for instructions on how to safely access
01:06and secure these connections. Finally, if none of these steps resolve the issue, there could be a
01:12deeper problem with the door mechanism or internal sensors. In this case, contact customer support or
01:18consult a professional technician for further assistance. And there you go. Your Ninja Air Fryer
01:24Pro should now recognize that the door is securely closed. If these steps don't work, reach out to
01:30customer support for further help. We've added the relevant links in the video description for easy access.
