What Door Means
This problem means the control board isn't confirming that the door or drawer is fully closed and latched — the safety interlock system that's supposed to confirm the door is secure before allowing the unit to run isn't getting a valid signal.
Common Causes of Door
- An obstruction preventing the door or drawer from fully closing
- A worn or misaligned door/drawer latch mechanism
- A failed interlock switch that isn't confirming the closed position correctly
🔧 One Safe Check You Can Try
Check the door or drawer for anything obstructing a full close (a shifted rack, food debris on the seal) and confirm it latches fully. On a drawer-style microwave, make sure nothing is preventing the drawer from seating completely.
⚠ Why You Shouldn't Go Further Than That
- The door/drawer interlock is a genuine safety feature preventing microwave energy from being generated with the door open — bypassing or forcing it defeats the exact protection it's designed to provide.
- Interlock switches are wired into the same high-voltage safety circuit that also protects you from the microwave's dangerous internal parts.
- A latch forced to "look" closed without actually engaging correctly can create a false sense that the unit is safe to run.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
