What to do if Progressive Dynamics Control Unit has no output?
- MMelissa LoweryJul 27, 2025
If your Progressive Dynamics Control Unit has no output, there are several potential causes. First, ensure the 120 VAC supply is properly connected. Check the AC distribution panel for correct operation. Inspect for a reverse battery connection, as blown reverse battery fuses can cause this issue; replace fuses with the same type and rating if needed. A short circuit in the RV circuits could also be the problem, so trace these for any faults. Overheating can cause a shutdown, so check the airflow and allow the unit to cool. Finally, over voltage can also trigger a shutdown; the converter will shut down if the input voltage exceeds 132 VAC, so check and correct the input voltage if necessary.
