If a 121X (1210 series) won't get below 55 degrees, check that it's level while running, that the thermistor is still clipped to the fins, and that there's airflow behind the fridge. A cooling fan helps a lot in hot weather. If it's warm on both AC and propane with the heat sources working, the cooling unit is likely getting weak. See our not cooling guide. For the 1200/1210, we carry the Nordic Cooling Unit 6610. The 1210 is discontinued, and Norcold's replacement is the Norcold N15DCSS. See our Norcold replacement guide.
