I have a Raypac C155A LP spa heater. won't light

I have a Raypac C155A LP spa heater. Approx 18 years old. MY pilot will light and stay lit. The wires from the pilot gen are very rusty. The heater will not turn on. I think I need to replace the Pilot gen. What do you think?

I would agree with you. The pilot generator has probably degraded over the years and is only proving enough millivolts to power the pilot but not enough to run the gas valve for your main burners.

Replacing the pilot generator, preferably the entire pilot assembly, will fix the problem.
