The sail switch senses that the fan is running, if it isn't then it shuts down before opening the propane valve. Find the sail switch , bypass it with a jumper and see if it will run though the entire startup process. If it does then the sail switch is bad.
Beside above, how do I reset my propane furnace? Once the gas has had time to dissipate, turn the knob to "Pilot. This should light the furnace pilot light.
Once you are sure the pilot light is on, release your pressure on the reset button. The main shutoff valve is usually located at the Propane Tanks. Make sure that the thermostat is set to heat and adjust it to the desired temperature and the furnace or furnaces should automatically kick on and off to maintain the proper temperature.
Ignition Lockout Fault flashes with 3-second pause. You are having an ignition lockout fault. That would mean that the electronics is not detecting a flame that MAY be there. Maybe a bad ground. Or, the sparking you hear may not be taking place at the place it should be. Sail switches find application in the detection of fluid flow and measurement of fan speeds.
A sail switch might be used to protect a fan forced pellet stove,central heating system, electric heating element from being energized before the air flow from the blower is established. How do you troubleshoot an Atwood RV Furnace?
How to Troubleshoot an Atwood Furnace Connect the Atwood furnace to a working power supply if the furnace is not starting or running as expected. Turn the furnace on to a set point above the current temperature and turn the main switch to "On" or "Auto" if the furnace is connected to a working power supply but is not producing heat. No amount of videos or replacement sail switches will make this problem go away or make me feel better about this bummer furnace. We now carry an electric heater on every trip and may not even bother to clean the sail switch a 5th time.
Yes, that means we are power pole campers until a permanent solution can be found for this Dometic furnace problem. Putting a microswitch directly in the airflow is simply a stupid design. I hope they fired the engineer who designed it. Want to wake up cold in the middle of the night to find your furnace has quit working yet again- get a Dometic furnace! End of rant. There are aftermarket heating options. I have used both with success. As with all heaters just follow the safety instructions Portable Buddy heaters.
I have installed one of these in my last 3 Escapes Originally Posted by EdColorado.

With cat fur flying all over our trailer I think the sail switch has a big bullseye on it Originally Posted by davidmurphy So far haven't had this issue with the version. Not really familiar with the inner workings of the furnace, but wondering if some kind of plexi surround or some similar material could be designed and mounted around the sail switch to put in in it's own sealed enclosure.
I believe the sail switch needs air movement to operate, no air, no ignition. Air movement means no blockage and any disruption will cause issues.
If anything, the supply air should be coming from outside and exhaust goes outside, so there should not be any air being pulled from inside.
Similar to a HE furnace, it has dual walled pvc pipe, the smaller is the supply and the larger is the exhaust, or vice versa my point is no air is consumed from inside the unit. So where and how is the lint getting on the sail switch? Does the exterior need a filter cover? You may also like:. BB code is On. Smilies are On. Trackbacks are Off. Pingbacks are Off.
