If I received a work invoice from someone that did a repair at my home that was full of incorrectly spelled words I would question his/ her abilities and qualifications to perform adequately. Perhaps I am just getting too old and frustrated and should keep my opinions to myself but in my older years it's the little things that are getting to me and I needed to vent a little. So, for all of those out there that have a problem with my comments...have at it. I have a very thick skin.

    I agree

    Most of these machines have spell check...............LOL

    Its not your experience I'm questioning.

    i will apply for the pro foum, thank you beenthere. anyway got the unit going bad board, and the way to check for reverse pollarity is , first one lead of the meter on the primery 120v hot side, normally the black wire . the other lead to the 24v side normelly the red wire. now if you 95volts add teh 24 volts to the 95 = 120 the theres is no reverse pollarity in this case , however , if there was a higher voltage like uh say, 130 then add24volts = 154 then thers is reverse a pollarity. sori abot d tipo. git a live.

    not exactly how i would do it but good for you. Ask how to do this simpler when you get inside the pro forums.
    You can't fix stupid

    That would actually be checking that the primary and secondary voltages are in phase, usually is only an issue on twinned systems that use a single transformer for control voltage, but separate power supplies for each furnace.

    To check for reversed polarity to a furnace control board you would check the voltage between the L1 terminal on the board and ground, and L2(neutral terminals) on the board and ground.
    If you get 120v between L2/neutral on the board and ground, the polarity of the line voltage is reversed.

    We are getting a bit more technical than is allowed in this forum...
    I can hear the sound of the headsman's ax swinging towards these last 2 posts even now.
    If more government is the answer, then it's a really stupid question.
