2014 jayco whitehawk 23mbh water heater

[Acano82]

Hello all,

I have a 2014 jayco whitehawk 23mbh and my water heater won’t work . Not the worst as we can make due with cold water during this trip. Just makes for quick showers.
Anyway, here is whTs happening. First when I Flip the switch I hear a lclick as if the spark is trying to come on and sometimes I get flame but it only stays on for maybe five seconds and then it turns off. It will not stay on. I’ve cleaned the Air shutter and the dusted everything off as best as I could. Checked the fuse , nothing. Does anyone have any suggestions about trouble shooting this issue? At this point I’m thinking is an issue with low gas pressure because I can’t see anything else wrong...
