New to this forum and have a Raypak 130A heater that has just started acting up on us. It intermittently won't stay running.
It will spark and open the valve and ignite the burner but then within seconds you hear the valve close and of course the flame goes out.
It mostly seems to happen on cool or damp mornings and will eventually stay running but it may take numerous restarts to do it.
Other times it starts up on the second spark cycle, which from day 1 seemed to be the norm.
I found PrivatePilot's thread pertaining to the same heater and saw in the last couple of posts the issue about gas pressure if something else in the house is using gas. I did a quick test by turning off the heater and trying it while the hot water heater was running and the pool heater started right up. Of course the pool heater had already been running for a while. I will take note in the morning if the pool heater doesn't fire right up to see if the hot water heater happens to be on.
Any other easy checks that I can do?
Thanks in advance.
