Joy, no, I only drop in here now and then when I have a moment, I'm not
subscribed. Usually I am fairly accessible through email and phone. :-)

I believe your heater is one of the older EX1800 models, so has no
self-diagnostics, therefore no flashing trouble codes. If it has sat for
a long time, I would suspect perhaps a stuck gas valve. If you can see
the gas line where it enters the heater (far passenger side of the van),
you will see the copper line screws into a fitting at the heater
sidewall. Using a blunt object like a screwdriver handle or the like,
tap repeatedly on the largest part of that fitting as soon as you turn
the heater on. Sometimes that will dislodge a stuck gas valve. Of
course, if you suspect the auxiliary battery is low, that should get a
voltage check as well - the heater will shut down below 11.5 volts. If
these ideas don't help, feel free to call me and we'll try to sort it out.
