My fridge seems to be running OK until I put some extra load onto the motorhome electrical system.....such as electric heater or air conditioner. Once the extra load is applied the fridge starts blinking a "Lo AC" code and starts to heat up. Have had to put the fridge on propane (off the AC) if extra heat or cooling of the motorhome are required. Presently setting in an RV park in Phoenix, have not had this problem at previous locations. Is it possible that the voltage supplied at our present location is not adequate to run all of the motorhome systems at one time?? Just trying to figure out if I have an actual problem or if it is a matter of the current facility not supplying the proper power.Thank you all for the help

First thing I would check is to see if you are getting the proper voltage to your coach, borrow or buy a tester to see if you are getting 110 volts to your outlets. I have also seen where a coach was only getting power to one leg of the coach, we turned the breaker off, unplugged the shore line, plugged it back in again making sure it was plugged in properly and luckily everything started working. Won't hurt to try.

I use a Progressive Industries Surge protector on my coach, but I also have one of these plugged into an outlet in the main living area. I usually take a glance at it a couple of times a day to make sure the power is up to snuff.AC Voltage meter

If you do not have a volt meter, crank up the generator and see if the problem goes away. I'd unhook from shore power first. If this solves the problem it's low voltage in the CG and moving closer to the transformer in the CG may help or a different CG.
