The short answer
On HEI models the door is not a passive panel. A latch draws it up against the frame, a lock is driven into place for cleaning cycles, and interlocks report the whole arrangement to the control. A door that no longer seals here is as likely to be a mechanism out of adjustment as it is to be a worn seal, so the mechanism is checked first.
What the mechanism shows
- The door closes but does not feel drawn in — It sits against the frame rather than being pulled to it.
- The lock is engaged or partly engaged when it should not be — Visible or audible depending on the build, and it prevents the door seating properly.
- Heat escaping at the top edge while a cycle runs — The most common place a partly closed door leaks.
Mechanism first, then the seal
- The latch not drawing the door fully home — It leads because on this build it is both the likeliest cause of a poor seal and the one owners never suspect. A door that is not drawn in cannot seal however good the rubber is.
- A lock that has not returned to its resting position — After a cleaning cycle in particular. It holds the door a fraction off the frame and it also prevents cycles, which is how the two complaints arrive together.
- Interlock switches reporting inconsistently — They are the reason a door fault on this designation stops cycles rather than merely spoiling results, and they are not adjustable by an owner.
- The seal itself — Fourth rather than first, deliberately. It does harden with age, but on this build it is usually found to be sound once the mechanism has been dealt with.
- Hinge tension — Last. A door that hangs presents badly to the latch, so it makes everything above it worse without being the original fault.
Work the mechanism before the rubber
- Close the door slowly and feel whether it is drawn in at the end — A door that stops rather than being pulled the last part of the way is the finding.
- Check the lock is fully at rest before anything else — Let a cleaning state clear on its own and wait for the lock to release rather than helping it.
- Do the paper test cold, at the top edge and the corners — It confirms where the door is not bearing, which usually matches where the mechanism is short.
- Listen for the mechanism when a cycle is requested — A sound with no movement points at the lock drive rather than the seal.
- Note whether cycles are refused as well as results being poor — Both together point at the mechanism; poor results alone point at the seal.
Before you open anything
Safety
Never force a lock, and never attempt to hold or wedge a door to improve a seal — the lock and the interlocks exist because a cleaning cycle takes the cavity somewhere an open door must not be. Switch the oven off at its breaker before removing any panel, because a capacitor can hold a charge after the power is off. A lock jammed with the door shut is a call rather than a project.
When to call a technician
Feeling how the door closes, waiting for a lock to release and doing the paper test are owner work. The latch, the lock drive and the interlock switches are not, on any build, and on this one they are matched to the control that reads them. Call when the door does not draw in, when the lock does not return, or when the paper test fails with the mechanism working normally.
