    How To - Sawstop troubleshooting replace brake cartridge error

    My saw recently gave me a "replace brake cartridge" error. The brake had not been fired and appeared to be fine. I tried my dado brake to see if I had a faulty brake, the saw presented the same error. At this point I was convinced its not the brake cartridges.

    I contacted Sawstop and they had me pull an error code for them.
    This is done by powering on the saw, pull out the paddle - as if to start the blade turning - and turn the key on the side of the "Powerbox" box. This will cause the left light to blink a few times then the right light to blink a few times.

    Count the blinks.
    Left light is the first digit and the right light is the second digit.
    Two left blinks plus three right blinks = error code 23

    The error code will be useful if you call support.



    In my case it was either the power supply (inside the powerbox) or the cable to the brake.
    Day 1, test it this way.
    Day 2, might be better to test this way instead.
    Day 3, this is the definitive test.

    My issue is tests 1 & 3 both involve opening the "powerbox". Since test 3 is the definitive test of the power supply why not do it first?

    1. Unplug the saw.
    2. Take off the left side of the power box.
    3. Disconnect RS-232 cable.
    4. Bend up a paper clip and place the ends in holes 6 & 8.
    5. Plug in the saw.
    6. Turn on the power.

    If you get a solid green light the power supply is good.
    If you get something else call Sawstop; likely a cable issue.

    In my case it was the cable. Once I replaced mine I dissected the old cable and found the problem. A soldering iron could have saved me $68.

    Well, the good news is now with a soldering iron you can have a spare cable.

    I would get back to Saw Stop Tech support and see what they say. This looks like a manufacturing defect and should be covered by warranty.

    Meh. I already pitched it. It lasted about 10 years.
