Tip & How-To about Stairmaster 4000PT Stepper

How do I test for continuity of the gray cable on my Stairmaster 4000PT?

Testing for Continuity of the Gray Cable on a Stairmaster 4000PT

  1. First disconnect the grey cable from the back of the console and UNPLUG YOUR MACHINE from the wall.
  2. If your cable has a 6-pin round connector, you will need to check pin sockets #5 (black wire), #3 (blue wire), #2 (brown wire) and #4 (white wire) with your ohmmeter for continuity in each pin. Should get continuity from all if cable is good.
If your cable is a 9-pin cable, you will need to check pin sockets #5 (blue wire), #3 (black wire), #2 (brown wire) and #4 (white wire) with your ohmmeter for continuity in each pin. Should get continuity from all if cable is good.

StairMaster 4000PT console gets pixalated, machine freezes after 15 minutes of working out


This really still sounds like a console issue. You can check your load resistor just to make sure that is not causing an issue. It should be labeled as to what ohms it is rated as. Simply unhook it and, using a multi-meter, check the ohms. It should be +or- 10%. I am attaching a link to a video on how to use a multi-meter just in case.

why does my stairmaster 4000pt randomly shut off

Check continuity of the console cable. If this checks out, open the console and look for any corrosion on the circuit board. If this seems to be the issue, you will have to find someone to repair the circuit board as they are no longer available.
