Water heater gas problem Cardinal 37RX
Water heater(Suburban) is full( checked via relief valve).
On batteries only for now.
Turned on water heater and no action. No spark at piezo, no gas smell either.
Pressed the reset button (12v) and tried several times to restart with main switch . Nothing.
Noticed when changing the valve for de-winterizing there was a circuit board that had come adrift and was attached to the main service to the heater.
Wondering if this is the source of the problem before I go through circuit test routine.
I assume this board is the setting for temp. Any other function?
haven't been able to get back to the unit to check.
Any thoughts appreciated
