Huffy Puff. Problem with the Norcold high temp fix is it does not work right. Have had to have mine replaced because the red led flashes and the refrig does not work in that mode. Some guys say you can reset with a magnet, but that did not work for me. Norcold would not send a new black box out so I had to take a whole day and drive 200 miles to an authorized service location to have them unplug old one and plug new one in. I could have bypassed, but with over 2000 fires, I am not going to do that. As soon as I can I will be replacing with a Sun Frost and will never, ever, consider anything from Norcold again. They are not at all helpful when you call them...worse than that...they are hostile.
