This weekend we traveled to Morro Dunes RV park in Morro Bay, CA. We had a great time with family, but it rained every day over the Thanksgiving weekend. Ugh!

Here is my problem. We have an OEM, Progressive Dynamics PD4500 Power Control Center (inverter/converter) installed in or 2016 3160 Legacy. When I’m connected to shore power, all the electronics, lights, water pump, etc. power on and off correctly. When I disconnect from shore power, all the electronic components that work off of 12 volts do not work at all. Everything is dead. My 12 volt deep cell battery is fully charged, my auto level system works just fine, but no other components work. I also noticed that there is no “hum” coming from the PD4500. I checked all the 120 volt circuit breakers and all the 12 volt fuses are fine. Nothing is tripped or blown. I’m suspecting that the PD4500 control board has failed and I may need a new PCC.

Has anyone else experienced this issue and how did you resolve it?
