Customer services contacted me finally after 3 days (have proof of that) They Failed to assess the situation correctly. My item fan stopped working caused the item to smoke and I got a final decision the item works, just a grease build-up, that because is smoking. After explaining them it smokes like a grill, because works like a grill without the fan, they finally agreed to return it. Took too long. However I fed-up with their "item works" decision and open it to have a look inside. Found a 150C thermal fuse glued to the fan winding was tripped. After replacing the fuse item work as it should. Definitely warranty issue.
