treadmill stops after 1 second
 

hi folks,
my treadmill has been in storage for a few months, i took it out for use & found it stops about a second after the motor starts turning (with no load on belt)
the problem is intermittant in that by persisting with the start & stop buttons eventually i can get the motor to run as it should & go for a run on it.once the treadmill is warmed up, however the problem does not reoccur.

i googled a bit & found a test to verify motor ok by connecting motor direct to a multimeter & reading off DC voltage at 3mph. i got 60v, which is well above the minimum generally acceptable 28v. i checked that the speed sensor is clean(even though it doesnt look like an optical one).

The controller board has a big cap on it & a relay. any ideas what to try next?
thanks

use a VOM to see what the motor voltage is........

When was the last time you waxed the area under the belt where you walk?
Is the belt sticking to the metal?

Does it show any error message when it shuts down? Will is start more reliably if you're pushing it in the right direction when hitting the start button? Better starting when warmed up sounds like a mechanical issue, not electrical - perhaps the walking belt is too tight or out of alignment and that makes for a hard start that the controller does not like and shuts it down? Did you check the walking belt? Is it overly tight? Are the rollers and other turning parts lubricated?

Which treadmill is it, by the way? Is this a Pro-Form? Those (and perhaps most others) use high voltage DC motors and, although I don't remember what the actual voltage reading across the motor should be at a particular speed, if you're finding it to be higher than normal, it means the motor is trying to pull harder and something is obstructing the movement. Lack of lubrication and over-tightened or misaligned walking belt would be suspects.

Have you visually checked the belt to see if it was tattered?

Loose/corroded connections can do some weird things. Have you
removed and reinstalled the relay if it's plug in style?

Lets start with make and model and how old, how long in storage,
etc!!!!!

Is there a safety string gizmo to attach to yourself that will shut it
off if you start to go flying off the treadmill?

If yes, check the switch for that. If mechanical, maybe the switch
contacts are dirty.

Does the problem occur when cold if you are not on the belt? IIUC the
person is a pretty big load. (especially the fatties who need to
exercise.) Oh, you say with no load.

If it runs with no load, a back up plan is to let it run unitl it's
warm and then use it.

You should be making a drawing of the board, or a list of test points,
Then you should be testing the voltage at all those points whne it is
running and when it is stalled. I gather the thing turns off a
second after it sttalls. So you may be only able to measure one
thing a day, or every few hours. Stil, each test will take less
than a minute.

Plus what the others siad. The most common problems with electrical
things are physical, not electronic.

I'm thinking an over speed shutdown. Well you said it was 60 volts. Do you
remember starting speed. Does it change as you fool around. Mine begins to
over speed after turn on, but settles down.

Examine the circuit board for hairline cracks, or brittle/loose soldered
