Oasis igniter failure

[newmarokie]

We just got back from South Texas. The first night out our oasis laid down. I was like Rich and had no new parts. I had a flame but terrible soot. It would and go to safety shut down. We were at the grandson's motocross race and boondocking. I opened up the oasis and removed both sintered filters and back washed with brake cleaner. I cleaned the nozzle with a welding tip cleaner and reassembled. The oasis worked the rest of the trip. I have a three year maintenance in the coach now.

Seasons Greetings to all!

I have a 2017 Ventana. I've done my ITR Oasis annual service as well as the three year kit. After only about six months after my last service, I began to see the red light below the burner switch that says heater module fault. So last week I installed an annual kit making sure I cleaned all parts as ITR recommends but I still do not get the boiler to ignite. I do however hear it attempt to start but no ignition. So I recorded the starting sound yesterday. It tries to start two times then the red flame out and fault light come on.

Does anyone recognize what this sound might point toward so I can diagnose what the problem is? If ITR was open today, I would call them and have them tell me what they hear to troubleshoot. They've been helpful in the past when the water temp sensor was the problem with no hot water.

If anyone can help me, I am eternally grateful.

I had the same issue on my 2021 Ventana. It was the flame sensor. Cost $145 from ITR in Vancouver, WA. Takes about 5 minutes to replace.
