Q:

Is the polarity of my Proform elliptical positive or negative?

A:

When making some major adjustments on an appliance, Manage My Life is here to help. While you are waiting for your expert answer, I suggest you add to the thread of this question and include the full model number of your appliance so that the expert can provide you with a more detailed answer. I know that only the expert can provide you with a wiring diagram and he or she will respond within 48 hours. I did manage to find a link in where you can enter your appliance model number and the owners manual will pop in where you can find some great information. I hope my link is useful.

The model number is 831.28543.1. I do have the owner's manual, which does not mention anything about polarity or even that it is possible to connect an adaptor and run the elliptical off of electricity. I only became aware of this when I had a repairman look at it, and he had an adaptor, which allowed him to run in on electricity. He told me I needed an ac to dc adaptor, 120v ac to 6v dc, at least 600 ma but not higher than 800 ma. I found one online but it has separate tips, which are connected one way for positive polarity and the other way for negative.

A:

Set it to the "positive" setting. What this is actually doing is determining if the center of the plug is positive or negative. You want the center to be positive for this machine.

If you have any further questions please let us know.

Thank you for using Manage My Life!

Are all Proform ac power adaptors made with positive polarity? I have PRO-FORM XP440R Bike Exerciser. What is the difference for regulated vs. non regulated?

A:

@Dann, they should all the be same if it's ProForm. It's just a DC transformer. I honestly don't know (dont recall seeing) if they are regulated or unregulated.

Q:

The resistance quit working on my Proform elliptical model 831.285431. I replaced the batteries. Any suggestions? please help

A:

You need to be sure the batteries are at full power. I assume the console display is working. If the batteries get weak the console will display but the resistance motor won't run.

The most common cause of the resistance motor not running is a broken or disconnected wire in the wire harness from the console down to the resistance motor and potentiometer.

I am sending you the wiring diagram for the eliptical so you can check the wires if you have an ohm meter.

If you have more questions send another email with the details of the checks you have made and we will try to get you the information you need.

A:

The adjustment knob assembly is basically held onto the pin with snap rings. It is possible that one (or both) of the snap rings has broken and is no longer there. It is also possible that the pin itself is worn out. It all really depends on how and where it is coming loose.

I attached a drawing of the parts (with the part numbers) that deal with the adjustment knob. If you’re looking at your machine where it’s loose you should be able to kind of tell on the drawing which parts are loose. In general I have to think it’s either snap rings or the pin. The pin has some sleeves that come on the pin itself, if those sleeves are worn, I could see the whole thing getting loose.

Let me know if you need further assistance and I’ll be happy to help.

If you need to order any parts you can HERE to order them. You can also use your model number at that site to pull up the parts images for your machine.

Thank you for using Manage My Life!
