No he's or hot water this am. WeilMcClain propane boiler. 

This am on inspection has fuel in tank, has power, circulators running, stats calling for heat. Lights on controller were as follows (green power-off, red tstat circ-on, red limit-on, red pressure switch-off, red flane-off.  When cycle power green power comes on tstat circ, limit and pressure switch all come on. Flame never lights and then unit goes back to condition on initial inspection. 

Any ideas.

    Not sure what control the light sequence is on . Is it locking out on pressure switch or open limit ?. Or are they both proven and not igniting ..What type of ignition ?

    There was an error rendering this rich post.

    "WeilMcClain propane boiler" is like saying my Ford Vehicle has a blinking light... What does it mean?
    Could be any of these discontinued boilers with a Red check.

    Or several of the current production models.

    Each one has a different control system
    You will need to be more specific in order to get help here

    Model number
    Series
    Picture
    Picture of control.
    Any other info you can provide will help.

    After you make that expensive repair and you still have the same problem, What will you check next?
