Carlin EZ gas going on lock up

rich11coop Member Posts: 25
OK installed & converted from oil back in early Oct. everything has been running fine until today. Today I broke into the one return to install purge valves at both the boiler end & at the main end and flushed tons of mud. After I was done skimming, turned the boiler on & the primary control LEDs went nuts green, amber, red flashing. Eventually settled down to amber purge fan on for 15 seconds flame established for 15 seconds & then would abruptly shut off & go into solid red lockup! Thoughts? Getting the two fireplaces burning going to get cold tonight!

    Never seen that

    and we have a bunch of EZ-Gas burners out there. I'm assuming the flame actually did light for those 15 seconds. If not, there's something else going on.

    Did you disconnect the gas to the burner while working on the system? If so there might be air in the line.

    Since the job is that new, call the company who put it in. It should still be under warranty.

    Never mind!

    Thanks steam head for the fast reply.

    I think the processor was retarded for a bit.

    I turned the power off for awhile & when I turned it back on it was back to normal, all is good & we are making steam!

    Thanks again!

    Glad it's working

    If it happens again look for a flaky ground connection. The flame sensor circuit is sensitive to any intermittent connections in the grounding.
