The water heater works fine on electric setting, but when I try to use it on propane the DSI will not ignite or even make a sound. After water cooled down I tried the DSI switch and the red light will not even light up on monitor panel by red Heater switch. There is propane in the tanks (furnace heats up), the fuses are OK, all wires I see on water heater outside & behind monitor panel are connected. All I can think of is Heater switch went out inside on panel? Any helpful ideas would be appreciated.
