Kenmore Range F7 Error: Function Key Stuck or Shorted on Keypad
The kenmore range f7 error is a fault signal from the control board — this guide walks through what it means, common causes, and safe diagnostic steps. What Does Kenmore Range Error Code F7 Mean? F7 on a Kenmore 790-series gas or electric range stands for Function Key Stuck or Shorted. The Electronic Oven Control […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
Maybe. Normal cooking may be possible between F7 alarms if the stuck-key condition is intermittent. However, the control panel cannot be fully trusted until the keypad or board is repaired. Do not leave the range unattended with F7 active.
Can I reset the code?
Yes. Pressing Cancel clears F7 temporarily. Because the underlying stuck key or shorted membrane contact is still present, F7 will return — often within minutes. Repeated clearing is a short-term workaround only.
When to stop immediately?
Stop if you notice: F7 returns within seconds of being cleared and cannot be suppressed long enough to complete a cook cycle, Any key produces unexpected results — entering values not pressed — indicating multiple shorted contacts.
Symptoms You May Notice
F7 appears on the display with an alarm — often without any key being pressed
The fault appears spontaneously, often when the range has not been recently used. It typically starts as an intermittent alarm and display flash before becoming persistent, because membrane delamination initially causes intermittent contact before becoming continuous.
Control panel buttons are partially or fully unresponsive
With a key stuck or shorted, the EOC board cannot distinguish valid new key presses from the continuous background signal of the stuck key. Many control panel functions become inaccessible.
F7 clears temporarily after pressing Cancel but returns within minutes
Pressing Cancel resets the fault flag, but because the physical key contact or membrane short is still present, F7 returns as soon as the board re-polls the keypad — often within 60 seconds.
Oven beeps continuously even when no one is using it
A persistent beeping tone emits from the control panel while the range sits idle, sometimes for hours. The tone may pulse or stay constant, and pressing Cancel only silences it briefly before it resumes.
Possible Causes
Delaminated or moisture-damaged membrane keypad
The membrane keypad layer has separated from its backing or absorbed moisture, creating permanent contact between a key circuit trace and its return trace — producing a continuously active key signal. This is the most common cause on ranges more than six years old.
DIY PossibleDebris or spill-over under a keypad key bridging the contacts
A liquid spill or food debris on the control panel has wicked under the membrane layer and is physically bridging one or more key contacts, creating a stuck-key condition.
DIY PossibleFailed EOC board keypad scanning circuit
The keypad scanning matrix circuit on the EOC board has failed and is detecting a phantom key press that does not exist on the actual keypad. Board replacement is required.
Requires ProfessionalSafe Checks You Can Do

1
Press and release each key firmly to free a physically stuck key
Press Cancel/Off to clear the F7 alarm. Then systematically press and release each key on the control panel firmly — some keys can be freed by pressing and releasing them briskly if they are physically stuck rather than electrically shorted. Note which key (if any) feels different — sticky, harder, or soft — compared to the others. Restoring a stuck key to its released position may clear F7 temporarily.
If F7 clears after pressing a specific key that felt sticky, that key is the culprit. Inspect the membrane surface around that key for moisture or debris. A delaminated membrane must be replaced — pressing the key repeatedly is a temporary fix only.

Inspect the control panel for moisture or spill entry
With the range powered off at the circuit breaker, remove any control panel trim pieces that are accessible without disassembly to look for moisture entry or food residue behind the membrane keypad surface. On some 790-series models the membrane can be peeled back slightly from the edge to examine the contact layer for liquid damage. Do not attempt to dry the membrane with a heat gun — this warps the plastic layer permanently.
A moisture-damaged membrane keypad rarely recovers permanently even after drying. If moisture entry is confirmed, budget for membrane replacement rather than relying on a dry-out period.
When to Call a Professional
Contact a qualified technician if:
- Membrane keypad shows visible liquid damage, delamination, or burn marks — requiring membrane replacement
- F7 persists after confirmed membrane replacement, indicating an EOC board keypad scanning failure
- Multiple keys read as simultaneously pressed — a pattern consistent with either a badly shorted membrane or a failed board scanning circuit
