GE Oven F7: Identified Function Key Stuck Continuously
F7 means a specific function key (Bake, Broil, Self-Clean, or Convection) is permanently registering as pressed. Unlike F0 (unidentifiable phantom input), the ERC can identify exactly which key is stuck because the row/column intersection maps to a known function.
F7 vs F0: Precision of Failure
F0 = random traces shorting (multiple intersections, moisture/contamination). F7 = one specific key's traces making permanent contact (localized membrane defect). F7 is more diagnostic — the ERC reports which key is affected.

The Oven Cleaner Connection
F7 correlates strongly with oven cleaner spray. Caustic chemicals (sodium hydroxide) seep into the membrane through edge gaps or display window cutouts. The chemical attacks silver ink traces, causing them to swell and make unintended contact. F7 may appear days after the cleaning event as the chemical slowly penetrates deeper layers.
Can Drying Fix F7?
Unlike F0 (where moisture evaporation sometimes works), F7 from chemical damage is usually permanent. The caustic has altered the trace material itself, not just added a conductive bridge. Replacement is typically required.

Parts and Pricing
| Part | Cost |
|---|---|
| Touchpad membrane | $65-$150 |
| Combined touchpad/ERC (if separate unavailable) | $250-$400 |
Professional repair: $225-$475. ERC replacement is rarely needed for F7 since the board correctly identified the stuck key.
The Real Cost of DIY
Average DIY attempt: $150-400 in tools you may use once, plus the risk of further damage. Our diagnostic visit costs $0 — we find the problem and give you an honest quote.

Prevention
Never spray oven cleaner near the control panel. Cover the touchpad area with tape or plastic wrap when cleaning the oven cavity.
