In case the hot heater starts you could conclude that air entrance is causing the real issue.
Rv gas water heater won t stay lit.
Atwood water heater won t stay lit it is the dsi model with propane 120 vac and motoraid heat exchanger.
When i turn it on it fires up for about 10 seconds then stops then fires up again and keeps repeating this cycle as long as the switch is on.
Again easy fix quick solution.
Dirt and debris can collect in the pilot tube causing the flow of gas to be blocked.
If air manages to enter the lp or the liquid propane lines it becomes a hindrance to the water heater and it won t light.
The last step of the rv water heater troubleshooting process is to turn off the lp system to check for a spark.
As a result the pilot doesn t get enough fuel to stay lit.
If your gas water heater doesn t stay lit you may have a defective control thermostat.
The gas supply to the pilot assembly is controlled by this valve.
Don dear don this is a result of the control.
Okay but what if you get through each of these steps and still can t figure out what s wrong.
If you don t get a spark your system could have an electrode that is bent or carbon grounding.
Thankfully a dirty pilot tube is the easiest issue to fix.
It tries several times and then quits.
To detect whether it is the air causing the problem light the stove burners and consequently switch on the rv water heater.
