Is the box with the red light on Rev E of the Nocool band aid? Since you have a red light, you have 12V. There is a slight possibility you had a overheating of the flue and this pos did what's it's supposed to do... shut your reefer down. There is a good possibility it malfunctioned (even revision E) and there is nothing wrong with your reefer. You need to smell and look for yellow staining at the back of the unit. If you do not smell rotten eggs or see yellow stains then a strong magnet will reset a Rev E box or you can bypass it. Either way you need to monitor the unit for overheating and not cooling. After a couple hours you should have a decrease in temp on the back wall of the freezer which means your unit is OK. If no decrease in temp you need to shut it down and take it in for repair. Good luck.
