I purchased a 2008 Phoenix Cruiser Model 2400 several months ago. The gray, black, fresh water and voltage monitor panel did not register correctly, even after replacing the tank sensors. I needed a new circuit panel for the monitor system that is mounted on the cook top vent hood. Phoenix Cruiser was not much help in locating a new circuit board. I called Ventline/Dexter, the hood manufacturer (574-848-4491). They were great. I gave them the number on the back of the circuit board (L5096-54) and they had a new one made for $65.00. Now it works!
