Microwave will not start; display shows E1 immediately or when START is pressed.

Safety first: Unplug the Danby microwave from the wall outlet before any inspection. High voltage is present inside even when unplugged; do not access the magnetron or capacitor area unless you are trained.

• Check door closure: Ensure the door closes fully and evenly. Inspect the plastic latch hooks on the door for cracks or bending. If damaged, the door assembly must be replaced.
• Test door switches (basic check): With power disconnected, open the control panel area only if you are comfortable removing screws. Locate the door switches near the latch assembly. Gently press each switch actuator by hand; it should click crisply. A mushy or stuck switch likely needs replacement.
• Check alignment: If the door sags, lift it gently while closing. If this allows the unit to start, the hinges or latch bracket may be bent and require adjustment or replacement.
• When to stop: If the E1 code persists after confirming the door closes properly, the door switch(es) or wiring harness likely need replacement. Because the door interlock system is a critical safety feature, contact a qualified technician if you are not experienced with microwave repairs.
