I purchased this unit in 2013 and only used it for camping 5 or fewer times per year.  On my last trip it stopped working and I'm trying to get Norcold support to tell me what is wrong with it. Norcold has referred to the troubleshooting guide in their manual which is very limited and  is of no help and only refers to set up problems. My digital panel blinks "000" where the temperature is supposed to show and after about a day of blinking it shows a temperature of "48" degrees F. which then cannot be adjusted.  Their response to my problem was to send it to a NJ service center. Their 2 year warranty is very short and shows a lack of confidence in this product.  I still have a similar size unit that was purchased about 30 years ago that works fine.  I believe that the problem is with the new digital panel that they now use. Also, this unit was manufactured in China and the quality is suspect.  Update - After further diagnosis I found that the problem was a bad fuse in the DC cord.  It would have been nice if the Manual diagnosis chart mentioned this.  Nowhere in the Manual did it state that there was a fuse in the DC cord.
