How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- 1. Clean the panel: Wipe the touch glass with a soft, dry cloth to remove any residue or moisture that may be bridging keys.
- 2. Drying time: If the fault occurred after cleaning, leave the oven powered off with the door open for several hours to allow moisture to evaporate from behind the panel.
- 3. Inspect for cracks: Check the glass for visible cracks or impact damage. A cracked touch panel usually requires replacement.
- 4. Internal inspection: Remove the control panel and inspect the UI PCB for corrosion or liquid marks. Clean lightly with isopropyl alcohol if minor, but replace the board if tracks are damaged.
If the panel remains unresponsive after drying and cleaning, replacement of the touch control assembly is typically required.
