There is a rotary switch /thermostat right (stove) side bottom corner and a little inside the back. Get a mirror or phone picture, I ended up taking mine out to find it, if you do that careful not to scratch the finish on the wood, its VERY easy. Mine was all the way off from the factory as well, switch is NOT easy to find. It does require shore power so make sure to keep a few beers inside to drink while the others cool
