Stairmaster 4600 Cl Cordless Freeclimber - Page 3 - Answered Questions & Fixed issues

http://support.nautilus.com/support/stairmaster.jsp?lid=StairMaster you can download and view all manuals here. If by drive sprocket you mean the hub that both step chains go over.....replace the entire hub. faster easier and less hassle. cost difference is about 40 dollars.

I had the same problem. It turned out to be the lower control board. It is easy to replace and you can order it online. I payed about $65.00 after returning the old board.

Pull the lower covers off.Disconnect the white and brown wires from the alternator.Begin stepping.When you stop stepping see if the display remains on instead of shutting off.If it stays on then it is probably the lower control board. National Gym suppliers have them for about $65.00 if you return the old board.This is how I fixed the same problem on my 4600CL.Also...an additional problem I had that changing the board solved was the resistance level was stuck at highest(hardest) level. After changing board was able to change levels in addition to the console remaining on when stopping.

Hi,
It the steps seems to be loose then it is clearly the hub assembly and pedal chain.Tighten the pedal chain with wrench.
Still the problem persist check the alternator brushes.

Please do rate the solution if the issue is resolved or post a comment for further assistance.

What has happened is the control panel is bad and you need to replace it.

Good Luck

Hi, I just purchased a used StairMaster 4600CL last week, and found a link for an owner's manual that covers the StairMaster FreeClimber 4200 PT, 4400 PT/CL, and 4600 PT/CL. This is a free, .pdf download:

hi
i think you have bad timing belt usually you tighten it through alternator bolts

if it is skipping you should check one of crank bearings it could be gone bad

hi
if console is on it is not battery problem
it is alternator or MCB board

it is usual for these units MCB fails

hi
DATA CABLE is wire between console(top part)and alternator controller (in the body of stair Master
they call it data cable

yes it happens when one of the cables from tension coil dissplaced or alternator controller is bad
check it for all loose wires and check bettery and alternator controller if heats up
call me 347 515 8670 for controller needed

I provoked that on my machine by turning on "clinical mode". It was OK after turning it off again: ^, 3, enter, then select your way to clinical mode, enter, turn it off, enter.

Hi,

Take side panels off, you have on the right side the alternator on top, middle pulley and bottom eccentric hub assembly on each side of the pedals are return springs disengage them. their a braket that holds the alternator loosen bolt so that the Poly-V Belt can be removed. Now inspect by hand if thier is a slippage both ways on the eccentric Hub assembly if so replace the eccentric hub assembly .

Remove console knobs form the back of the console, lift the up, and disconnect the 20 pin cable from the console. Get a multi meter go to dc volts 100v range. On the connector you will be testing for 12 to 19 volts. When Looking at the connector the connector nipple should be pointing left starting form the bottom left odds numbers right bottom even you will hunt for pin 1 Neg pin 10 Pos. If all voltage readings are within 12 to 19 volts and the console is not powering up , then either replace or have the console repaired.

Typically, the stair master should gradually increase in speed from lower levels. If it's not speeding up until level 8, there might be a malfunction. It could be a setting or technical issue. Have you checked the manual or contacted customer support?
