Electrical issue

Parked our fleetwood coronado and hooked up to park power. Turned off both batteries. Everything worked for 2 weeks but now the fridge will only work with the aux batteries on.

If you have an RV fridge, they require 12VDC to operate the control panel.
I don't understand why you turned off the batteries. Shore power will not be able to charge the banks if you've turned them off. A lot of the house stuff runs on 12V and get their power from the converter/inverter, that is fed from the house bank.

Good afternoon. Thank you for the reply. We are new RV ers. When we parked I plugged into shore power and turned off main and aux batteries. Everything worked fine for 2 weeks then the fridge now only works if the aux batteries are on.
