    32M88 board with "missing" DIP switches

    This question is for a professional only who is familiar with 32M88 board !!!!

    The original Surefire board failed within 2 days in a brand new Lennox G41UF furnace and a serviceman replaced it with an OEM replacement board 32M88, which works perfectly since.

    This board has a double dipswitch (SW1 & SW2) to adjust "Fan-Off" time (60/90/120/180 sec)

    However, it looks like, the board was designed for two additional dipswitces just located below, because it has 4 holes drilled out, and on the rear side of the board, foil + resistors are connected to the "missing" switches.

    Anybody has any idea, what would these two "missing" switches control ?

    Cool off fan timer ?
    second stage fan timer ?

    Thanks!

    I have posted this question as a "NEW TOPIC".
    Received an e-mail notification about that someone has replied:

    Dear jenom,

    karsthuntr has just replied to a thread you have subscribed to entitled - 32M88 OEM Board "missing" dipswitches - in the Residential HVAC forum of HVAC-Talk: Heating, Air & Refrigeration Discussion.

    This thread is located at:
    http://HVAC-Talk.com/vbb/showthread....7&goto=newpost

    There may be other replies also, but you will not receive any more notifications until you visit the forum again.

    All the best,


    When I clicked on the link in the e-mail above, to my surprise, I found myself and my question posted in which looked like some other thread, with replies which are not related to any way to my question:
    "Look at the bottom"" Get a refund""etc...."

    Looks like someone managed to MOVE it to the wrong thread !!

    Please DELETE it from there, and leave it as a new thread, so hopefully someone will provide useful information !


    Thanks!

    Why don't you ask your contractor who installed this?

    No DIY help is allowed. Call the contractor the serviced/installed your equipment.

    Also, one thread per subject. Please read the rules, there is a link in my sig line.
