I have a 2019 Coachman Catalina Legacy Edition. I have electric and gas hot water heater. The electric part works fine. The gas part doesn't. I have gas to my stove and fridge. I purged the lines. Turn the switch on inside and it turns red like it is suppose too. Do not see or hear the igniter at all. I did clean the probes of soot which was hardly any at all. Any ideas? The fuses inside in the panel at floor level was all good. Breakers was good.
