Possible Causes
Failed internal power supply on control board, Loose low‑voltage connector, Shorted low‑voltage component, Overheating of power supply section
How to Fix / Troubleshooting
Safety: Disconnect power before removing the cover.
- Visual inspection: Look for bulging capacitors, burnt components, or discoloration on the low‑voltage section of the main control board.
- Check connectors: Ensure any plug‑in low‑voltage harnesses are fully seated.
- Thermal check: After re‑energizing (cover on), feel the outside of the enclosure. Excessive localized heating may indicate a failing supply.
- Resolution: The low‑voltage supply is typically integrated into the main control board. Replace the main control board if E10 persists and supply voltage to the unit is stable.
