    HELP!!! Main burner won't light

    Heatilator gas fireplace main burner won't lite.

    Pilot lights and stays on. (knob is turned from pilot to on)

    no response from wall switch (resistance measures 0 at wall switch)

    touching wall switch wires together = no response

    thermopile read 500 millivolts....lowers to 270mv when wall switch turned on.

    jumper will start main burner.

    What would be the next diagnostic step??

    Thank you for any advice.

    There = not here. Their = possessive pronoun. They're = they are
    It's = contraction of it is. Its = the possessive form of it
    Too = also. To = expressing motion. Two = 2
    Then = after that, next. Than = indicates a comparison.
    Questions should end with a question mark "?" Statements end with a period "."
