my dometic dm2652 will cool to 38-40 degrees hold for about 24 36 hours and temp will rise to 80 degrees. lp or 110. burner can be heard on lp even when not cooling. roof vent is clear. does not matter setting of thermistor.
Make (other): keystone
Engine: travel trailer
taken it to dealer. for 2 weeks. they can not duplicate concern. pick up from dealer let run at my house for 2 days stopped cooling. let sit for 24 hrs tried again 2 days later stopped cooling. back at dealer now can not duplicate concern after 12 hours. they don't want to mess with it anymore. unless i pay them. still under factory warranty
