RV Repair: hydro flame 7916-2, hydro flame, unit thanks

Question
The blower comes on but will not light and burn. The ignition works as I can hear it snap.  I turn on the three burners to the cook top and noticed that the flam for each burner would fluctuate.  I banged on the regulator then tried the furnace again and it now works.  I had a problem before when it did the same thing but I have no clue how I fix it that time.  It's a 2003 unit. Also I followed the steps for starting and shutting down the unit.  Thanks.

LP appliances are difficult to diagnose. But if the "bang" test reset the regulator replace it immediately..don't run it till it gets replaced. After replacing it if the trouble is still there,make an appointment and see a "PRO".
I don't cut my own hair...and not because I don't have scissors, I know better. Leave it to a professional.
