    BDP DAY & NIGHT Furnace Model #394JAW036065
    The blower fan won't shut off unless you push the door switch. Blows cold air, fan never shuts off Any Ideas? Should I replace the high limit switch and circuit board? I have found the parts online and also found a Digital Circuit Board upgrade raising the cost from $70.00 to $148.00. Is it worth the difference? Help!
