    So after the pilot comes on you do not hear/feel a click of the main valve opening? Have you tested to see if you have 24 volts at the valve?

    Is this natural or LP? Did you confirm that you have a pilot light before the gas valve main opens/clicks? Have you tested the gas pressure coming into the unit?

    Smell any gas when you hear the valve click? Has the unit been in place running for some time and now just having issues?

    OK. What gas valve did you install on the unit? With no gas pressure on the manifold side of the valve can mean either the gas valve is locking up or not enough pressure. 7"WC should be enough incoming.

    Re: Raypak RP2100 digtal pool heater

    OK so you got a direct replacement valve. What is the gas pressure on the manifold side? There is a test spot on the valve that you can hook into. Curious to know what that reading is since you have 7" coming into the valve, what is the valve passing thru it. How does the inside of the heater look? Burners look OK?

    Well then it almost sounds like the control board is not truly signaling to the valve to open.
