Most RV Pros will tell you to go with an RV Fridge and not residential.I assume people think residential is better or maybe because they are larger they are wanted.If you still have problems after you have made adjustments and waited long enough to have the temp stabilize ,then you probably need a tech to look at it and possibly replace some parts.They are very simple to work on.Everything is plug and play these days.Look up whirlpool fridge problems on the internet and you can probably figure it out by yourself.Hope it works out for you.
