    This is from the manual for my DM97 Daikin equivalent.
    If you need the manual @yoop just pm me your email.

    OK......so I did some digging, and it turns out I had two spare boards. The second board had the memory chip taped to it. I put the chip on the new board, fired it up and ..................same original problem.( E2 low fire switch stuck open.)The low fire pressure switch has three taps. Two on the front and one on the back. It's tubes tie into an H fitting along with the hire fire switch. Something's weird. Calling tech service Monday morn. It's beer oclock!!

    It looks like the VS blower is “supposed” to upload the needed information the to board.
    And, if you changed the blower, the board would program the blower.

    You should only need the chip if all communicating devices were killed at once.

    Thanks for the info. There was no other communicating equipment so a chip was required. Me and Jack been going at it for almost an hour now. Better if I wait till morning and go back at the furnace when I'm good and sober.

    "So the whole problem started when I decided top pull and clean the burners."

    Sounds like a hose or wire got misplaced in the reassembly process. Seems odd the board would take a dump just from cleaning the burners but possible I suppose.

    26.2 volts across 6 & 12. I've got to be missing something simple.

    Only pulled the ignitor, rollout, and sensor wires. When I put them back, I saw one hose that had fell off (connected to back of low fire pressure switch.). Hooked it up to the only open tap on the H fitting.

    How do I check the vacuum on this low fire pressure switch when it has 3 taps on it? Two on the bottom and one on the back. Takes .17" wc to close it. High fire switch closes but low fire won't. It's not a bad pressure switch. I have 3 of them and changed to make sure.

    I bought one and figured it would help me keep up with how to fix this new stuff. Then one day I BUMPED my head and sailed to the land of belts, sheaves, cans and cans of refrigerant, and etc.
