Norcold 1210 cooling during Travel

Thanks for the suggestion. I actually devised an air scoop on the bottom exterior vent to help with the air flow. I tested it with a leaf blower and it really scooped a lot of air and forced it right out of the top vent. So I thought this was the ticket. Made NO difference at all. I'm starting to think that the fins are not sealed well enough where they come into the interior of the box. Therefore, while driving the wind turbulence outside is forcing the air through to the box??? Who know. Now I'm planning to add some sealant around the interior cut-out where the fins enter the box to see if that helps. Phillip

10 years ago, Norcold had a problem with a few hundred 1200(1210 now) models where the cooling unit was NOT sealed correctly to the box. The result was--- cooled fine stationery and raised in temp in transit. The ONLY way to determine this was to have a Norcold authorized Service center to test the refer and using the customers complaints(always a temp rise in transit), they authorized the center to pull the refer and the cooling unit a reseal correctly. THERE IS NO WAY TO DETERMINE THIS WITHOUT PULLING THE REFER AND THE COOLING UNIT). You cannot add any sealant to fix this type problem. IF under warranty, get it in and have them contac Norcold with your history of this complaint. If all other parameters check out, then they will authorize this type repair. IN your case, I would also verify that the evap drain tube does have the check valve installed and that the LP pressure is at least 11.5 inches. LOW LP pressure can also cause your type problem. If you had a motorhome, I would instruct the customer to run the APU and run on 120 in transit to see if the heat rise happens on 120. Doug
