I have a Raypac 2100 (nondigital) pool heater. When my pool was opened, the heater didn't work: the pilot stays on, but the heater doesn't ignite, at all. I would think it's the thermostat or igniter, but the pool company that has come out (which I'm beginning not to entirely trust) says that it needs a new gas valve (which doesn't make any sense to me, since the pilot is operational), or, preferably a new heater. Since I plan to put my house on the market next spring, I would obviously prefer not to spring for a new heater. I called Raypac and they said they don't speak with end users. Any suggestions?
