    I have a friend that has a coleman model DGAT070BDC
    BTU/HR 70,000 YEAR 1994
    ok about 3 weeks ago he had no heat in his mobile home
    t-stat was not working replaced t-stat worked but then i noticed on a call for heat inducer motor goes on ignitor glows main gas opens fires up then after maybe 10 or 25 seconds it goes out then re-lites agian sometimes three x before works normal.
    that day i was only there 2hrs he had to go to work.
    falt code is for flame sensor flame week.
    he told me a year ago someone change his control board when he had no heat.
    this control board is a robert shaw 780-910
    or model HS845-34P-1L-4T
    his flame sensor is not going to the control board he has a jumper that came with the board.
    i tried plugging his flame sensor in the board nothing flame sensor is no good.
    my question is this the right control board for this furnace.
    he also told me it will go off sometimes in the middle of the nite.
    called me today told me it is going off at nite and he has to turn t-stat off and on to get it to go back on, he said he had this problem last year too ever since the control board was changed.
    anyway he had a sears tech out there and he left scratchin his head.

    I'd about bet the board is the least of this problem...
    When all else fails - play dead.
