Atwood water heater malfunctions

Thanks westend & 1fastdad! The RV dealer cleaned the electric connections as did I awhile back, so we're reasonably sure they're O.K. The propane dealer checked out the thermocouple & said it need'nt be replaced. One thing I forgot to mention, outside wind doesn't seem to have much effect on it. Sometimes it lights better with the access door open, but not always! Last week it stayed working through some pretty good winds- yet went out a day later while it was calm. That's why this this thing's making us crazy. I'll mention the gas valve to our propane supplier and see what can be done with it.
Thanks Again.
