If you haven't adjusted the belt refer to your owners manual for the proper procedure if you still have the same results then it could be caused by a lack of lubrication under belt or a worn belt.

Treadmills are usually made up of various components. The rolling surface (tread) is usually placed on a set of rollers when the unit starts due to the low friction between both the surface (tread) and the rollers the surface (tread) starts slowly while the rollers move regularly and the sensor is placed on the movement of the rollers.
What you need to do is get the unit serviced usually there is a way the tread it tightened to have better grip on the rollers. This method differs from one make to the other so get an expert who knows about proform rollers. Once the system is tightened the problem will be solved.
Hope this solution has been helpful?

SOURCE: I have a Proform 545s treadmill with incline and

i have a proform 545s as well and it would light up when pluged in but you could not use the speed settings at all. i figured out how to fix it just by tinkering around with it. i removed the back cover on the programer up top and exposed the circiut board. there is are 2 ribbon like sets of wires that come from the speed controler. the plug into the circuit board with a whit clip. pop loose the white clip on both of there and you will see a series of prongs that come in contact with the ribbon. using a small flat head screwdriver you must bend these prongs in slightly to close the gap between the two. it took me a couple tries to bend them enough to make contact again. i tried it and to my surprise it works great. the fan still is not working but i am trying to trouble shoot that now. hope this helps you....

SOURCE: my proform xp slows below the set speed, the motor wines and after forty minutes starts to smell

Dear Sir:
Please RUN THE software calibration for easy diagnose and troubleshooting, and adjust the speed sensor see the diagram attached.
And you will see the problem with the motor, possible lack of LUBE, and maintenance.Now you test the motor for lubrication and maintenance too.

Weslo Cadence G-40 during operation there was a loud pop and an electrical smell, as if something blew or burned. Since that time I've been using it and notice a minor slowing and recovering of the belt...

You must test the motor, and tight the electrical connection very well. and see if there some burn wires, or any board of the elliptical. See my personal TIPS.
And test the electrical wall, and see if the voltage is o.k .
However keep you eyes open, for any inconveniences. Suspect of the motor winding.
God bless you

2001 aurora when fan is on high for a period of time it smells like the header is burning.

Not sure what a burning header smells like, but I would expect two possible smells. First, if the blower motor itself is going, you might smell the windings getting hot - like a transformer burning. If this were the case I would expect that the motor wouldn't spin on the low speeds.
The other smell you sometimes get is when the heater core leaks. Then you will get a coolant smell inside the car and sometimes (usually) a wet carpet as well.
