How to Fix / Troubleshooting

Safety: Unplug opener before drying or inspecting. Water and electricity are hazardous.

Identify leak source: Inspect ceiling/roof above opener and repair any leaks.
Dry components: Remove cover and allow the opener to dry completely. Use a fan; avoid direct heat guns on plastic parts.
Inspect for corrosion: Check logic board and connectors for corrosion or mineral deposits. Clean lightly with contact cleaner if minor.
Seal housing: Ensure the cover is properly installed and any wire entry points are not large open gaps.
Replace damaged parts: If corrosion is extensive or operation remains intermittent, replace the logic board or opener.

Water or moisture inside opener housing; intermittent operation after heavy rain or humidity.
