How Dometic and Norcold RV Fridge Works

Bill Gehr from Trailer Life ABCs of RVs explains how the Dometic and Norcold RV fridge works, which in turn teaches why the Fridge Defend is needed. This video shows the fluid flow created by the cooling unit boiler and teaches why the boiler is the heart of the RV gas/electric fridge, and the Fridge Defend is the pacemaker insuring a long life. Bill Gehr started his 50-year career in the RV industry when he went to work for an Airstream dealership. After the gas shortages in the 1970s, Bill decided to start his own business and opened up Bill’s RV Service in Ventura, California. After several years in business, he met Bob Livingston, and together they worked on hundreds of technical editorial projects at his shop while becoming great friends. Bill eventually joined Bob on the TV show “RVtoday,” filming a number of hands-on projects. After retiring, Bill headed out full-time in his fifth wheel and toured 39 states while writing technical articles for Trailer Life and MotorHome magazines. He now is Technical Director for RV Enthusiast. More on this subject: https://www.arprv.com/how-dometic-nor...
