I stay here by myself and just turn it off, till i have the courage to try again.
I sure would appreciate any advice on what I should do or am I over reacting?
Your Direct Spark Ignitor (the clicking you're hearing) will attempt three cycles to ignite the propane before going into a lockout mode (you have to turn the switch off, wait a hair, then turn it back on to override the lockout). Your light inside tells you the propane has not ignited, until it goes off...then you are good. If it stays on, then the propane did not ignite, and you are most likely in the lockout mode (which stops the propane too).
In a perfect scenario, the propane ignites on the very first cycle and it's good to go. However, it may not, and then go to a second cycle or even a third....before lockout occurs. If it goes to a second or third cycle, there may be some excess propane circulating around, which is the whoosh you may be hearing as it ALL ignites.
The system is designed to safely go thru the three cycles. However, if it doesn't light after 3 cycles you may want to wait a little and allow any excess propane to dissipate before attempting another go....after resetting the lockout if applicable.
There can be several reasons for the heater going to a second or third cycle if it does. You could have a dirty/partially clogged flue, the electronic ignitor could be weak/misaligned or other. Wind blowing hard onto the side of your RV where the water heater is, also can affect it.
