Twowhlrcr Report post Posted January 2, 2015 Good afternoon Guys. I have a trailer with a Dometic Americana Model 2652. When plugged into A/C, the refrigerator works great. When I unplug and run it off of gas, it doesn't cool at all. I have a good flame I think...see picture. The flame stays on constantly but does not cool the refrigerator. Any ideas on where to start? Should I inspect the area just above the flame for a clog of some sort? I appreciate any help. Thanks. Share this post Link to post Share on other sites
dickandlois Report post Posted January 2, 2015 The heat from the flame needs to rise freely up the flue. This assures even heating of the hear exchanger. You should be able to remove the roof cover and check for restrictions in the vent cover also look down the flue. Any restrictions need to be cleaned, like mud dabbers nests, wasp nests, and other items like baffles that have dropped out of place due to deterioration. Look for any deterioration of the flue pipe itself. Rich. PS-- The flame looks clean and directed up the cone properly ! The lower portion looks very clean, with no rust or other restrictions.

Twowhlrcr Report post Posted January 4, 2015 Removed the refrigerator. The flue is spotless. The baffle is still in the tube. Man, this is a tough one? My Father In Law thought it was flame related originally, so the control panel and thermocouple have already been replaced. Share this post Link to post Share on other sites
huffypuff Report post Posted January 4, 2015 You need a RV tech to put gauges on it so pressure and flow is adjusted properly. Service manual below list to check pressure as one item of troubleshooting for no gas operation. Not cooling on propane. . http://www.nationalserroscotty.org/resources/dometic-service-manual.pdf Share this post Link to post Share on other sites

Twowhlrcr Report post Posted January 5, 2015 My Father In Law just called and he said the refrigerator is working as of right now. Thanks for the help. He might have found a loose fuse. I'll be in touch if it fails again. Share this post Link to post Share on other sites
