Had similar issue on my Horizon WS150. Hopefully my fix can help you. My
biggest issue is these parts are no longer available and was reluctant to get a
whole new system.
Easily disassembled – remove vane, then top is just friction fit with o-ring
seals to main body to access circuit board. While the board is not
serviceable, my issue was the wires are extremely thin and the solder
connections failed / in process of failing. Most likely cause is corrosion
over many years. Used electronics pencil solder iron to carefully resolder.
Reassemble. Works perfectly.
