Here is some links that gives a lot of good advice on troubleshooting the Dometic units. It also explains a number of reasons why they do not perform as expected. It should be noted that most of our units are 20 years old and they just no longer perform as they did new. The abuse of using them in closed vans in summer has surely also taken its toll on them. FWIW the wattage of both the 12 volt and 120 volt heaters is 85. The BTU input on gas has to be fairly close as to much heat will also stop the unit from working and damage it. Dennis

Looking further into Mike S's question, does anyone know how much propane the Dometic uses in an hour? or its btu/hour rating? When running on 12V, the Dometic's 96 watt dissipation converts to 330 btu/hr. In comparison, the Norcold's 15W converts to 51 btu/hr. -- Mike "Rocket J Squirrel" Elliott 71 Type 2: the Wonderbus 84 Westfalia: Mellow Yellow ("The Electrical Banana") 74 Utility Trailer.
