Star Trac TR4500 Treadmill. Need help connecting the display

Hi. I recently purchased a second hand and non-working treadmill. I have fixed everything except for connecting the display board back up which was seperated when I purchased it.

It looks like the Polar Heart Rate board & Contact Ring board connected to a combiner board but I cannot see where this connects.

Also these is a stop button that needs to be connected. There is a terminal on the display board labelled stop but it has four terminals and the connector on the stop button has only two.

I have looked everywhere for photos, cct diagrams etc but can't find anything.

    Hi dswanger. Unfortunately they don't show connections for the display board.

    I got in touch with a guy from Star Trac support just today who by the way was brilliant!

    He posted a diagram on the site for me... here is the link just in case someone is interested.

    I have a TR4500 that I just aquired. I'm looking for a nice used or new display housing. Star Trac doesn't have them. Any ideas?

  • Topnikko May 11, 2010

    I have a TR4500 as well and need a front plastic display housing for it. Either a clean used one or new. Star Trac doesn't have them. Does anyone know where I can get one?

    I have a trimline 7000-1 treadmill that is working fine with one exception-- the entire display panel stopped displaying all information. Is there a fuse or connection somewhere that I should check? One day it worked fine and the next it was out, no jars, jolts etc. Can anyone help?

My treadmill will start and you can increase speed and incline but fan will not work and you can not decrease speed or incline. And I can not stop the treadmill. I have to emer. stop.

I'm not sure if this will help.

First I was unable to identiy your model. Star Trac makes 'S Series' treadmills and Pro Tread DC (5500 Pro S model) treadmills. Can you be more specific on your model?

Second. I have used Star Trac customer service in the past and they are the best. They are responsive, and knowledgeable, and will provide troubleshooting flowcharts to help you solve your problem. I highly recommend giving them a call.

Hope this helps,

Clean or repair sticking buttons on TR4500 display

This should be a warranty issue. Sometimes the keypads fail and need to be replaced, they are not repairable. Generally you need to remove the console covers to get at them upper control board. Then you need to peel off the keypad (usually this is like a bumper sticker. There will be slots and electrical ribbons from the keypad which are inserted (pushed into) the control board. with the replacement keypad carefully insert the ribbons into the slots and stick the new pad on the console (remember you get one shot), so carefully push it down, reattach the ribbons and put the console back togethyer
