in Gas Heating
The line running to the power switch has power

The transformer doesnt have any.

It was working just fine.

Again, new install.

What happened to make my transformer on my boiler no longer have power?

    If you have the owners manual for this Williamson boiler you should read it.

    If your steam boiler has a low water cut off switch (which it should) it may have
    detected a low water condition and shut the boiler down and if the low water cut
    of was installed as the first boiler control it would have shut all the power off to
    the boiler just as mine is wired to do so.

    You should contact the plumber who installed this boiler for help.

    I am the plumber, but i never wire the boilers, another guy did.

    Turns out he messed up the wiring to the transformer.......

    Electricity, like water, goes where you let it. Glad he/you got it figured out

    If it did work previously, wiring will not fix itself.

    How much water is in the boiler, perhaps the LWCO shut down the power.

    Or another simple fix could be the draft hood temp sensor, usually has a reset button.
    Flue/chimney lack of draft would open this.

    Then the front above the burners is a flame roll out switch/fuse. Usually a one time fuse.
    Means something major wrong.
