Hello I have an attwood water heater that won't work on gas or 110 volts. I checked the 2 amp fuse and the breaker. When you hit the gas side it dose nothing at all. Thanks for any help. Kenny
As Chris suggested.........check that thermal fuse It's a one shot fuse that trips on flame blow back. When it trips ALL 12V DC power is tripped so WH will not operate on electric or gas due to the use of common t-stats
Provided this WH is in your 2005 Newmar or the 2007 Dolphin and not one of the older RVs you have listed
