ones embassy fire-up problem

Here's another Onex issue- a unit I installed 5 years ago won't fire up. The flame comes on, runs for a few seconds, and snuffs out. I've replaced the ignition electrodes and the flame sensor, and even took the whole burner assembly out and tried it in another unit, where it worked fine. I also replaced the power control board- same problem. It won't stay lit even when I force it with the + - buttons, so I can't check the combustion settings. Any thoughts?

    Grounded properly? Gas pressure ok? Where you located?

    When you say it snuffs out define "snuffs out" is it floating around just exactly what is the flame doing. During the time it is lit and running (few seconds) what do you have for microamps.

    Check air intake and exhaust for any blockage, the fact that the burner assembly worked fine in another unit says the problem is somewhere in the equipment. Also make sure your pressure switch and combustion blower are working correctly. Finally check the condensate line .

    Are you getting any diagnostic codes when it fails?

    Don't you just love it when someone drops a problem on the board and then never answers any questions we have about a solution....
