I have tried to reset the button but it won't stay in. I think it is too old. 18 years is pretty good life. I will check the fridge tonight. It is cooling great right now. It is the only thing working on the 120 v. The guy that repairs my bigfood in Vernon, BC thinks it is the GFCI plug under the sink. I email him. The way I understand it from him is that all of the inside of the camper is controlled by the GFCI under the sink except the fridge. The only worry I have is every once in a while I am having a little beep like the microwave is getting just a little power.
