Long story to be hopefully short.Heater ran for few minutes,flame would shut off for 30 seconds or more then flame would kick back on again,it would take 20 min to raise a few degrees.Also would take 3 to 4 times to lite off when called for.Changed Thermostat and checked all wiring,did find the ground wire barely attached but still didn't help. Took to dealer and the bench tested heater and said sail switch is bad.I stressed to test heater since I will be away all of April for work and need heat in my trailer.They tested and it ran fine.Get to campsite try heater and it's pretty much still doing the same thing,it will run a little longer than before but flame still shuts off when running and still tries a few times to light.Anyone else had similar issues that I can have dealer check,it goes back in 2 weeks to have it looked at again.
