Question: One part of the power in my trailer goes out several times in an evening: TV, stereo, lights over the couch, lights in the kitchen, carbon monoxide detector, fridge, bathroom lights and bathroom exhaust fan. Then after a minute, give or take a few seconds, it comes back on by itself. What would cause it to do this ? HELP
Answer: There could be various causes. We are assuming that you are plugged into 110 power. We are also assuming that part of your list (such as the lights) run on 12-volt DC and the other appliances (such as the TV, Stereo, fridge) are on 110-volt AC.
It could be that something is wrong with your converter or a bad ground. It could also be a loose wiring connection somewhere in the trailer.
You mention that part of the power goes out. It might be helpful in your troubleshooting to consider which appliances, etc. do not lose power. Perhaps this will be a clue as to the source of the problem.
Another thought is that you might have some sort of thermal fuse or breaker that is sensing that a circuit is overheating and automatically shutting down power on that circuit for a few minutes until things are cooled off.
If you have access to the trailer schematics, owner’s manual or can contact the trailer manufacturer, they may be good resources.
