The short answer
This is the broadest oven designation in the brand’s roster and the arrangements under it are not uniform, so a door complaint starts with which door. On a tall installation the two cavities are used differently, worked differently and age differently, and the seal for one is not necessarily the seal for the other. Read the plate, then work out which door is leaking.
What to establish before anything else
- One door leaks and the other is normal — The most useful observation available on these models, and a free one.
- Heat or steam escaping at a specific edge — Note which edge; it points at the hinge side or away from it.
- The lower cavity is the one affected — Common, because the lower door is usually worked harder and closed less carefully.
- Discolouration on the trim between the cavities — Heat escaping upward from the lower door marks the strip above it first.
- Both doors feel the same and results have still changed — That moves the investigation away from the doors entirely.
Once the door is identified
- The seal on the affected door — First once the door is identified, and it is the part designed to be replaced. A seal that has hardened on one door while the other is supple is about as clear a finding as this subject offers.
- Hinge tension on a heavy door — Tall installations use substantial doors and the hinges are under real load. One that has weakened lets the door hang and meet the frame unevenly.
- The installation itself — A built-in housing that has moved, or an appliance refitted after a kitchen alteration, loads the frame and changes how both doors sit. It explains the case where neither door tests well.
- A displaced rather than a degraded seal — Free to correct, and worth checking on both doors before anything is ordered.
- The door glass assembly — Last, and specific to heavier doors: an inner pane that has shifted changes the way the door closes and is not an owner repair on any of these arrangements.
Identify, test, then compare
- Read the full designation off the plate on the door frame — It decides which arrangement and which parts are in play before anybody orders.
- Do the paper test on both doors, cold — The comparison is the point: a door that fails where its neighbour passes is diagnosed.
- Feel for escaping heat during a bake in each cavity — Locate the edge as well as the door; it distinguishes a seal from a hinge.
- Look at both seals for hardening, gaps and seating — They will usually be at different stages, which is informative in itself.
- Ask whether the kitchen has been altered around the appliance — A housing that has moved explains a fault affecting both doors at once.
Before you open anything
Safety
Test cold. The doors on these installations are heavy, the glass retains heat, and a leaking door can leave the trim around it hotter than expected. Switch the oven off at its breaker before removing any panel, because a capacitor can hold a charge after the power is off. Do not attempt to lift a built-in appliance to inspect its housing.
When to call a technician
Identifying the designation, comparing the two doors and reseating a displaced seal are owner work and they make the visit much shorter. Hinges on a door of this weight are not, and neither is anything behind the appliance. Call once you can say which door fails the paper test and whether the other one passes it.
