F5/E1 flags a fault in the door lock assembly—the motor, latch, and lock-switches that confirm “locked” during self-clean. If the control doesn’t see a clean “locked” or “unlocked” signal when it expects one, it throws this code and may block heat or self-clean for safety.
How it usually shows up
You start self-clean and the oven won’t lock, or it tries to lock and keeps clicking. Sometimes the code appears after a cycle when the lock refuses to release. In either case, the control isn’t getting a reliable state from the lock switches.
Why it happens
Most F5/E1 cases trace to a weak or stalled lock motor, misaligned latch/strike, or lock micro-switches that don’t change state. Heat and steam around the console can oxidize connectors; door hinges that sag over time can shift alignment so the latch never reaches the switch. Less often, a damaged wire harness or a failing electronic oven control (EOC) breaks the logic path.
What to do first (safe basics)
Cut power at the breaker to protect you and the electronics. Let the oven cool if it recently ran; a hot latch can bind. Restore power and watch the startup: if the lock motor cycles but never finishes, you likely have a mechanical or switch issue; if nothing happens at all, suspect the motor circuit, harness, or control output.
Targeted checks
Open the console area with power off and inspect the lock harness and connectors. Reseat plugs until they click, and look for heat discoloration or corrosion on the flat terminals. Manually move the latch (power off) to feel for grit or binding; a sticky latch won’t let the switch change state. If your model exposes the lock micro-switches, verify their actuators move crisply and aren’t bent; a lazy switch can read “locked” only halfway, which the control treats as a fault.
Repair logic
Start with alignment and connection: clean and reseat the harness, realign the door strike so the latch meets it squarely, and retest. If the code returns, replace the door lock assembly as a unit; that gives you a fresh motor and switches and eliminates the most common failure points in one step. Only move on to the EOC if a known-good lock assembly still triggers F5/E1, because control failures are much rarer than mechanical or switch faults.
After the fix
Power up and confirm the display initializes, the lock engages and releases on command, and normal Bake reaches setpoint. Run a short, supervised self-clean initiation to verify the lock sequence completes, then cancel and ensure the door unlocks without delay. Clear stored codes per the tech sheet for your model.
When to bring in a pro
If the console or connectors show heat damage, if you can’t access the lock without removing fragile trim, or if the door never lines up even after hinge adjustments, call a certified technician. A pro can test the motor and switches under load, confirm control-board outputs, and recalibrate door alignment so the switches report cleanly.
Prevention that actually helps
Avoid slamming the door; that warps hinge geometry and shortens switch life. Keep cleaners and steam away from the latch slot and keypad edges. Don’t start self-clean if the oven gasket looks deformed or if racks press against the door—extra pressure can jam the latch and trigger F5/E1 again.
