Does the red light come on when you turn the switch on? It should go off when the water heater lights. I assume it doesn’t go off.
Yes, picture or model # is helpful. When I first tried to light our Suburban SW6DE (and it wouldn't), I found a mud duaber nest the size of the palm of my hand that was there when we bought it.
I did get it to light after the mud nest was removed, but it's never lit easily and always burns with a deep orange flame rather than the blue flame you look for. I replaced everthing but the lp valve and cleaned every orafice but no improvement.
