# LG wall ovens

### Built in, and sharing a brain with the ranges

LG’s wall ovens come single, double and as combination cabinets with a microwave above the oven; LG STUDIO is the finish line rather than a different machine. The control board, the sensors and the published failure codes are shared with the freestanding and slide-in ranges, which is why the F-series list on this site covers both.

### Why the code number matters more here

On a range there is one oven and the code tells you what. On a double wall oven there are two, and the code tells you what and where. F1, F2, F6, F7, F9 and F10 belong to the upper cavity; F4, F5 and F20 belong to the lower. That distinction saves a visit’s worth of guessing on the appliance where guessing costs the most, because reaching the wrong cavity means taking the oven out of the cabinet twice.

Built in, and sharing a brain with the ranges

LG’s wall ovens come single, double and as combination cabinets with a microwave above the oven; LG STUDIO is the finish line rather than a different machine. The control board, the sensors and the published failure codes are shared with the freestanding and slide-in ranges, which is why the F-series list on this site covers both.

Why the code number matters more here

On a range there is one oven and the code tells you what. On a double wall oven there are two, and the code tells you what and where. F1, F2, F6, F7, F9 and F10 belong to the upper cavity; F4, F5 and F20 belong to the lower. That distinction saves a visit’s worth of guessing on the appliance where guessing costs the most, because reaching the wrong cavity means taking the oven out of the cabinet twice.

### The top oven works and the bottom one does not.

On a double wall oven that is close to a diagnosis on its own, because the two cavities have separate elements, separate sensors and, in the code list, separate numbers: F4 and F5 are the lower oven thermistor and F20 the lower door lock, against F1, F2 and F10 for the upper. What they share is the control board and the supply, so a problem that takes out both at once is a different and usually simpler thing than one that takes out either.

### The door locked during self clean and has not unlocked.

Give it time first — the lock will not release until the cavity is genuinely cool, and on a well-insulated wall oven that is hours, not minutes. If it is cold and still locked, the motorized latch or its switch is the failure, and on a built-in that is a real job because the oven has to come out of the cabinet to reach it. F27, a cooling fan stalled during self clean, is the code that turns this from an inconvenience into a reason to stop using the oven.

### Is a built-in harder to repair than a range?

Sometimes, and it is fair to say why. Everything electrical and everything thermal is the same. What differs is access: a wall oven is screwed into joinery, carries its own weight on a cabinet that was built around it, and has to be drawn out on a stand before the back is reachable. We plan for that, which is why a wall oven visit is booked differently from a range visit.
