Possible Causes
Failing low‑voltage power supply on control board, Loose low‑voltage connector, Shorted keypad or accessory connection drawing excess current
How to Fix / Troubleshooting
Safety: Disconnect power before accessing the control electronics.
- Inspect control board: Remove the control cover and visually inspect the board for bulging capacitors, burnt components, or discoloration around the low‑voltage section.
- Check connectors: Reseat all low‑voltage connectors, including those to the keypad, external automation interface, and any sensors.
- Disconnect accessories: Temporarily disconnect any external control wiring (e.g., RS‑485, relay inputs) to see if the error clears, indicating an external short.
- Board replacement: If E10 persists and the display remains unstable, the internal power supply on the control board is likely failing and the board should be replaced.
