Had this before and lost it Purchased new one worked fine?!

Bought this adapter to power the fan in my brand new heater, because the heater runs through batteries. The adapter worked for a few hours, then I realized sometime later that the fan was no longer running. After taking it out & putting it back in, trying a different outlet, trying the adapter in multiple heaters, I determined the adapter had died. Took it back to the store & they exchanged it with another one. Plugged the new adapter in & it worked fine -- for 6 hours. And then it refused to work again. Started looking for reviews to see if it was an isolated incident, and people have been leaving reviews about this same problem going back 4 years. Called the 1-855-663-0660 number that Mr. Heater puts in their review responses -- it goes to their "social response" team who proceeded to tell me they've never had a problem with adapters. So I start reading the reviews of all of the other people who've reported the same problem. After that, she said there's nothing she can do except send me another one and it would be quicker for me to just take it back to the store & get another one. Good luck!

Simply Doesn’t work !!!
