HWH 325A Circuit Board

Hi all,

Has anyone removed the circuit board from the control box on an HWH leveling system? Mine is a 325a system and I can see, and have removed, 2 screws from the bottom edge of the board but it is still attached very tightly to the inside of the metal control box. There are 4 or 5 large multi-pin connectors coming in the back of the metal box and I imagine the connectors attach to pins on the board, but I'm not sure. As it has proven difficult (impossible) to undo these connectors, I would like someone who has done this to let me know if that is the way to proceed. I don't want to break anything and make a bad situation worse.

Thanks,
Eric

    Thanks for that. The CN2 connector is the only one I've tried to remove. The top latch is missing and I can undo the bottom one but the connector just won't budge. Some of the problem is the awkward angle I'm forced to work at. I guess I'll just have to try harder. It seems the PC board is faulty and if I can get a replacement or have this one repaired, all those connectors need to come off. Ugh.

    I've looked through every service doc I can find at HWH and none of them discuss removing that PC board. I guess it's not the big deal I think it is.

    Thanks again,
    Eric
