My rear air will not run on any mode. Front works fine. Checked both fuses and both have power both sides. Checked at air-conditioner and no power. Controls set for proper air. What is next before shop? Brick
On 30 amps my power mgmt system sheds one ac if I turn on the microwave, vacuum, or electric heater. It will have already shed the elec water heater, inverter/charger. Residential fridge seems to have highest priority. On 50 amps...no problems. Generally no issues with 5.5kw genny unless at altitude where genset output is decreased.
Do you have a energy management system that is shutting off the rear A/C?
Will both work on the generator? IF both work on the generator, then it is a energy management problem. Plugging into a 50 amp electrical service might also solve the problem.
We have to flip a switch down under the edge of the bed that opens to see the water tank to get the rear to run. In middle position neither will run. It is designed to not fully load the generator with just the AC units.
