You are testing for 12V DC Voltage at gas valve..correct?
Even if gas valve was stuck open (you would hear/smell propane all the time in outside compartment) it would not light off unless spark electrode ignited the main flame....which it can't do without 12V DC power.
Bad t-stats for propane side.......they are the ones on right under 'push to reset' cover. They are 12V DC.
If t-stats are bad (failed close) propane will continue to burn/heat until PRV blows (210*F/150#)
I agree with "Old Bicuit" I think the high limit (high temp.) T Stat
is shot. If water is flowing out the pressure relief, shut it down ASAP. You know what happens if the pressure relief valve fails...Boom.
