Question and Answers

Q:

DP Treadmill Model 21-2865B

A:

Thank you for your question.

I am sorry you are having a problem with the treadmill. I have looked up the model number you have submitted. The motor on the treadmill is a one-speed ac motor. The treadmill uses a variable pulley to change the speed. The crank on the console moves the motor forward and back. As the motor position changes the pulley, side does too. If the motor does not move when you turn the crank, the problem is either a broken speed assembly or crank. I looked up the part numbers and both of them are no longer available. I do not know of any other parts that will work on this treadmill.

Please let me know if you need further assistance.

Thank you for using Manage my life.

Q:

DP gympac 1500

A:

Thank you for your request for a instruction manual for the old DP gympac 1500. I have looked a number of places but could not find the manual for this gym.

I found a lot of references to the manual but could not find the actual manual.

I would suggest spending sometime on the some search engine web sites and you may be able to find one.

Sears sold a number of models of the DP gym Pac but I do not see a reference to this model.

I am sorry that I could not help you.

Q:

Why won't my DP treadmill model 10.55GI set the speed on the console?

A:

There are several different models of the DP 10.55GI treadmill. I looked at the owner's manual for model 374.288450. Here is a link for this manual: Owner's Manual .

This manual shows troubleshooting for several different problems. It is unclear to me whether your motor runs at all according to your details. You indicate that nothing happens when you press the increase speed button.

If the motor is not running at all, you will need to verify that you have voltage at the motor controller. Although I normally do not recommend voltage checks unless you are experienced at safely making them, your details indicate that you have already safely made several voltage checks on the treadmill. I recommend that you use extreme care to safely make voltage checks. I recommend that you check the line voltage to the motor controller according to the troubleshooting tips in the manual. The line voltage is supplied to the motor controller through the black wire that connects between the blue wire on P1 and the two black wires that go to the motor on M1 and M2. The neutral connects to the motor controller on the N connector. See the wiring diagram on page 12 of the above manual. If you are getting the line voltage at the motor controller, you will need to check for DC voltage going to the motor on through the M1 and M2 connectors. You will also need to check for an open tachometer circuit. These troubleshooting steps are described on page 11 of the above manual. If you are getting no voltage out of the motor controller then you will likely need to replace that board. If you are getting voltage and the tachometer circuit is okay, then the drive motor may need to be replaced if the wiring between the controller and the motor is okay.

If the motor runs but will not adjust speed, you could have a failed console. I would need more details regarding what is occurring when you attempt to increase speed and what speed the motor is running to advise you accurately on troubleshooting a failure to control speed.

If you need more help, resubmit your question with additional details.
