How to Fix / Troubleshooting
Safety First: Turn OFF power before accessing control wiring.
- Step 1 – Check for moisture: Ensure no water leaks are dripping onto the control module or wiring.
- Step 2 – Inspect harness connections: Reseat all plug-in connectors between the switch module and the Tweeny main PCB.
- Step 3 – Disable remote features: If your model has wireless or app control, disable these features and test using only the physical switch.
- Step 4 – Power cycle: Turn off the breaker for 5 minutes, then restore power to reset the logic.
If E16 or random operation continues, the main control PCB or switch module may need replacement. Until repaired, leave the breaker OFF for safety.
