Last summer when I went to fire up the propane pool heater, the readout was illegible as I attempted to press the button that scrolls through the functions. I replaced the face plate readout hoping that would solve the issue. But, when I went to fire up the heater, the characters on the readout were funky.
So, I am wondering if I need to replace the circuit board. I am not sure how much money to invest in the heater as it is 10 years old. I don't use it much because of the cost of propane. However, on special occasions it's nice to ensure the water is warm for guests.
I have thought about exploring solar heating, but my pool builder just told me yesterday that a solar heat system was very expensive, and I would be better going with a heat pump, which would run me around $4,000, and cost only $50 a month to operate.
So, should I take a chance on the circuit board?
