How to Fix / Troubleshooting
Safety: Unplug the unit before inspecting electronics.
Steps to stabilize operation:
- Disable auto-restart (if available): Check the user manual for any auto-restart or timer features and adjust as needed.
- Power reset: Unplug for 10 minutes to clear temporary glitches.
- Inspect keypad: Ensure no buttons are stuck or pressed by dirt or warping. Clean the panel surface.
- Use surge protection: Plug the unit into a surge protector to reduce memory corruption from power spikes.
- Replace control board if behavior persists: Erratic, unexplained changes after other checks usually indicate a failing main control board.
Test: After any repairs, monitor the unit over several days to confirm that it only turns on/off and changes settings when commanded.
