A member asked whether the failed red 2/3 indicator light on a rocker-style tank and battery monitor panel can be repaired or if the entire panel must be replaced. They clarified it is not a tank sensor problem, but the small indicator LED used with the F, 2/3, 1/3, and E level display.

A member asked whether the failed red 2/3 indicator light on a rocker-style tank and battery monitor panel can be repaired or if the entire panel must be replaced. They clarified it is not a tank sensor problem, but the small indicator LED used with the F, 2/3, 1/3, and E level display.
Another member suspected the lights are LEDs mounted on a circuit board, meaning diagnosis or replacement may require board testing and soldering. The same member suggested checking the back of the panel for a part number, contacting the panel manufacturer or service source for test instructions, and noted that some RVers replace factory tank monitoring systems with aftermarket external sensor systems when they want better accuracy.
Bottom line: No confirmed fix was reported, and the choice between board-level repair and panel replacement remained unresolved.
