Raypak 2100, the old big green heater with what looks like a robertshaw ignition. I tried to warm the spa yesterday and it didn't get warm, so i checked and I could hear/smell gas but the thing wasn't hot. Where should I start checking?
i only have 4 lights, 2 green and 2 red. when the pump primes and flow is going, both green lights are lit. i think it believes it is started, but it really isn't.
also, where is the pilot light? if i take off the front cover i couldn't see it anywhere. is it lit 24/7 or does it only light on demand, then fire up the burners?
i dont know about electronic spark or milivolt. would pics help?
it failed my initial home inspection but i had the homeowner kick in 1200 towards replacement cost and had no problems running it for 3 years.
