We did not have one of the bad batch. It would shut down in the middle of the night. Only running a cpap machine. He took a 6 hour temp run a with out the vent on a cloudy day 70* temp. With the door closed got over a 50 deg. Heat rise over the door open. Said yes they would warranty it but next time it would something more costly and yes time down. Now with the vent it runs cool to the point it will not cook the grass yard it is sitting on. Before over night all grass under the back of the rigg would be dead brown
