What we can confirm
Code F7, from the manufacturer's own documentation
A code is only meaningful together with the machine showing it — the same digits mean different things on different equipment.
The code
F7
The control has been told the door is locked when it should not be, or cannot confirm the state of the lock while the cavity is hot. Almost every appearance of this code follows a self-clean cycle, because that is when the lock mechanism does its real work. The door will usually be shut and staying shut, and the correct response is to let the cavity cool completely before anything is attempted — a door forced while hot bends hinges that cost more than the lock.

What it narrows down to
Door lock enabled above temperature — the clean-lock or phase circuit is faulty.

On the same appliance
What else belongs to the wall ovens
On this make a code belongs to the appliance rather than to a product line. These are the other conditions this machine can display, and the models that can show this one — a display often has more than one thing to say, and the model number decides what any of it costs to put right.
Other codes this appliance can display
Shorted or jammed input device — a shorted wire or a failed membrane switch.
System watchdog circuit — the ERC's own self-diagnostic found a bake or broil system failure.
Heating mode high temperature — the control detected a runaway heat condition.
Shorted oven temperature sensor.
Open oven temperature sensor circuit.
ERC self-diagnostic failure — the control has failed its own test.
EEPROM checksum error — the control's stored settings no longer verify.
Door locking switch — the motor ran for two minutes without the phase switch changing state.
A control key has been stuck or shorted for a minute.
The door lock is mispositioned.
Communication interrupted between the main board and the sub board.
Communication interrupted between the main board and the touch panel.

About Oven error code F7
What F7 means on this make
The control has been told the door is locked when it should not be, or cannot confirm the state of the lock while the cavity is hot. Almost every appearance of this code follows a self-clean cycle, because that is when the lock mechanism does its real work. The door will usually be shut and staying shut, and the correct response is to let the cavity cool completely before anything is attempted — a door forced while hot bends hinges that cost more than the lock.
Where this appears, and which table it belongs to
On the appliance's own display. Photograph it before you cut the power: a display that has been cleared has taken the evidence with it, and there is no way to ask the machine for it again. Then check the model, because this make changed hands in 2016 and the two generations share no code string. The same characters mean different things on a Classic ERC oven, an ER-series range and a Modernist induction cooktop, and a meaning read off the wrong table is worse than no meaning at all.
Which machines this one applies to
Classic ERC wall ovens and ranges. The same number on a different appliance of this make is a different page and often a different repair, which is why this archive is organized by appliance rather than by number. This maker documents codes on 5 of the appliance types this site publishes — coffee machine, cooktop, dishwasher, oven and range — and publishes none at all for freezer, microwave, range hood, refrigerator and wine cooler. Those appliances have symptom pages here and no code pages, which is the honest answer rather than borrowing a table from the machine next door.
What to do about it
- Let the oven cool completely. Nothing useful can be done to a locked door on a hot cavity.
- Do not lever the door. The hinges are the expensive part of this repair when it goes wrong.
- Once cold, cut power for a minute — some locks release when the control restarts.
- If it stays locked, the lock motor, its switch and the phase circuit are tested as one assembly.
Where this goes next
The job this usually becomes is self clean and door lock repair, and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call (305) 363-6067 and describe what the panel is doing before booking anything.
