KitchenAid Range F7 E5 Error: Relay Stuck — Left Rear Burner
What Does KitchenAid Range Error Code F7 E5 Mean? F7 E5 on a KitchenAid electric range means the relay controlling the left rear surface element is stuck in the closed (on) position. When you turn off that burner position, the control board sends an open-relay command — but the relay contacts are welded together and […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. A stuck surface element relay is a fire and burn hazard. The left rear burner position must not be used and no cookware should be placed there until the relay board or control board is replaced.
Can I reset the code?
No. Welded relay contacts cannot be reset by cutting and restoring power. The element will resume heating immediately when power is restored. Professional repair is required before any use.
When to stop immediately?
Stop if you notice: Left rear element glows immediately after restoring power with no input, Element cannot be controlled by the surface knob or touch panel.
Symptoms You May Notice
Left rear surface element stays hot after being turned off
Rotating the left rear knob to Off or pressing the surface element Off key does not stop the element from glowing — it continues to radiate heat because the relay cannot open.
Cookware boils or burns unattended on the left rear burner position
Food left on the left rear element continues cooking at full or near-full power even with the control in the Off position, leading to boil-overs or scorching.
F7 E5 appears on the display only when the range tries to shut off the left rear element
The code does not appear during active cooking — it triggers only when the control board sends a shutoff signal and the element does not respond as expected.
Possible Causes
Welded relay contacts controlling the left rear element
Repeated high-inrush switching of the left rear element has welded the relay contacts on the surface element relay board or main control board.
Requires ProfessionalFailed surface element relay board (SERB)
KitchenAid electric ranges often route surface element relay control through a separate relay board — failure of the left rear relay on that board produces F7 E5.
Requires ProfessionalHigh-wattage left rear element drawing excessive inrush current
The dual-ring or power-boost element in the left rear position on Commercial-Style models draws more inrush current than standard elements, accelerating relay wear.
DIY PossibleSafe Checks You Can Do
-
1
Remove all cookware from the left rear element immediately
If F7 E5 appears and the left rear element is still on, remove any pots or pans from that position immediately to prevent fire or burns. Do not place any cookware on that element until the range is serviced.
Glass-ceramic cooktops retain heat for 10–15 minutes after the element is shut off even under normal conditions — with a stuck relay, the element may stay at full power indefinitely.

2
Cut power at the breaker if the element cannot be controlled
If the left rear element continues to heat after removing cookware and the display still shows F7 E5, switch off the range circuit breaker to eliminate the hazard.
Do not restore breaker power until a technician has confirmed the relay is repaired — a stuck relay may activate the element immediately on power restore.
When to Call a Professional
Contact a qualified technician if:
- Left rear relay board relay confirms stuck-closed with continuity testing
- Element reaches full heat output with control in Off position
- Multiple surface element relay faults appear simultaneously
