Just purchased a new Pioneer RG28. When I start up my refrigerator on gas, it works fine. When I turn the gas off, with the rv hooked to 30 amp service, the refrigerator check light starts to flash, and just the light inside is working. I hit the off switch to reset it and try it again. With the gas still off, I turn on the switch, and can here the ignitor attempt to light, but it can not, due to no gas of course. Instead of going to electric, the check light flashes again. I have the same refrigerator in my Rockwood and it ran on electric by itself. Also, the hot water heater is doing the same, real hot on gas, but hardly any on electric. When I did my walk through at the dealership, they had it plugged in and the gas on. Am I doing something wrong, or does it sound like warranty work? Thanks
