I just purchaced this RV.it has a elect. 3 position switch that has(on)on the top of the switch & (on) on the bottom of the switch.confuses me copletely. my girlfriend disconnected the water without turning off the switch that controls the electric side of the heater. i noticed this several days later. i connected the water supply & waited several hrs . i got maybe 10sec.s of hot water then it goes cold , so i flip the switch & wait. same thing 10sec of hot water then cold.i try the gas side of the heater, it ignites & runs for a period of time. the water is hot at first then just warm. i put my volt meter on the solenoid just to see & they are only getting 9volts.
Manual Yes 12 volts may help. I can't see anything about your switch from this manual
Testimonial: "thanks for your help.. i did hook a small 12v batt. with jumper wires. i disconnected the factory wires . it made lots of hot water. does that suggest that my problem mite be in the control board ? since im not getting a full 12v to the switches to operate properly ? do you think i need to replace the elect. element. i would prefer to operate elect. !!"
