Dometic Penguin II E7 error

Hello all!

we came home the other day to find out 5th wheel roasting. The center unit was off and showed an E7 error of which we know is the 120v lost. Its our second non ducted unit on a Dutchmen Infinity 3750 FL. The bedroom unit is still working just fine and there are no issues with the electricity in the RV park. The unit was set up as Zone 2 on our thermostat and had been working great for the last year until yesterday. I can select zone two on the thermostat and it reads it and shows the 'hourglass' symbol (compressor) but never fires up and will show the E7 error after a few minutes. Any ideas? its out of warranty so it will be my fix if I can do it. Thanks as always.
