I’ve got a cursed raypak 407. I was so excited to get a simple atmospheric heater with no complications when I bought it but I’ve had a variety issues with animals getting in, leaking sensors causing corrosion etc.
Now I’ve got it all cleaned out, everything seems to be ok, but it consumed a pilot assembly in a couple of months. Watching it run, the pilot is continuing to burn after the main burner has rolled on.
I would expect the sequence would be the pilot would start, the sensor would prove flame, main burner on, then pilot off. It seems like it’s just staying on. Is that right? I tried swapping the board with my spare and no effect.
