Rockwood freedom water will not heat

[Rpm90001]

Good morning, 2006 rockwood freedom water heater will not heat. Pilot works perfect, but burner will not kick on. Any trick or test to help get this going?

Thank you

What is the make and model number of the water heater? Your picture shows just part of the control valve.

Is the gas flowing? Check that no gas is leaking from the lines.

You've tried purging the lp gas lines by turning the propane stove burners on? There has to be enough gas flowing through the lines for it to turn on.
You've filled the water heater with water by turning on the hot water faucets in the rig til water, rather than air, flows out?
Then we need the information requested about the make and model.
How long since you've used the WH?

on the pop-up I had before the one I have now, I had that water heater. I sometimes found that although my pilot light was on my burner would not kick on. What worked for me was turning it on a little further. On your dial you have 'on' and a line, see if you can turn it to the line (if it isn't already) Sometimes my knob needed to be turned a little more!! (I think that came out right!!)
