Answer to continue safely
Is it safe to keep using?
Maybe. Bake mode and cooktop elements operate on separate circuits and remain safe to use while E7 is active. Broil mode should not be used. If your cooking workflow requires broiling, schedule repair promptly — the fault will not self-resolve and will remain until the element or relay is replaced.
Can I reset the code?
Yes. A power cycle clears the E7 display, but the broil element circuit remains broken. The code will return whenever broil mode is selected. Only element or relay replacement fully resolves the fault.
When to stop immediately?
Stop if you notice: If a visible break is confirmed on the broil element, do not use broil mode — a broken element can arc inside the oven and damage the cavity lining., If E7 is accompanied by a tripped breaker, treat the fault as a potential short circuit and arrange professional diagnosis before using the range..
Symptoms You May Notice
Oven top does not heat during broiling
Foods placed under the broiler receive no direct heat from above — browning and searing do not occur even after extended time under what should be an energized broil element.
E7 code displayed when broil mode is selected
The fault code appears specifically when broil mode is activated, while bake mode may continue to function normally if the lower element is intact.
Convection operates but broil element does not glow
On models with convection, the fan runs during a broil cycle but the upper element shows no visible red glow, confirming the element is not receiving power.
Visible damage to the broil element
The upper element inside the oven cavity shows a crack, burn hole, or discolored blister along its surface when inspected with the oven cooled.
Possible Causes
Failed broil element
The upper oven heating element has developed an open circuit, typically a physical break in the resistance wire caused by thermal fatigue over time.
DIY PossibleBroken element terminal or loose connector
The broil element's terminal connection at the oven cavity wall has failed or pulled away, interrupting the circuit without the element itself being broken.
Requires ProfessionalOpen broil relay on control board
The relay that routes power to the broil element has failed open on the control board, preventing voltage from reaching the element.
Requires ProfessionalSafe Checks You Can Do
-
1
Visually inspect the broil element
With the oven fully cooled and the circuit breaker off, look at the broil element at the top of the oven cavity. Examine its entire length for a visible break, blister, burn spot, or hole.
The broil element on La Cornue electric ranges is visible at the top of the oven interior. A clean break in the element often looks like a small gap or charred spot.
-
2
Inspect the element terminal connections
Look at the two points where the broil element connects to the oven wall. Both terminals should be firmly seated. Do not touch loose terminals — they carry 240V when powered.
A terminal that has pulled out of the wall connector is a common failure point, especially after self-clean cycles that reach temperatures exceeding 800°F.

3
Test bake mode independently
After a power cycle, select bake mode only (not broil) and verify the oven heats normally. A working bake mode confirms the control board, main wiring, and temperature sensor are intact — narrowing the fault to the broil element circuit specifically.
Documenting that bake works and broil does not gives your technician a clear fault profile and may reduce diagnostic time and service cost.
When to Call a Professional
Contact a qualified technician if:
- A resistance test across the broil element terminals confirms the open circuit — infinite ohms indicates a failed element requiring replacement.
- Broil element replacement requires reaching the upper section of the oven cavity, and on some La Cornue configurations the element mounting is behind the cavity liner — professional disassembly is recommended.
- If the element tests intact but E7 persists, the broil relay on the control board must be tested; board-level relay diagnosis and replacement requires professional service.
