Hello There, Thank you for all the information. It appears as if your walk belt is worn. What is happening is the friction from the bottom of the belt is actually causing the motor to overheat (there is a thermal cutout inside where the 2 blue wires go) When the belt wears the cloth on the underside becomes flattened out causing too much surface area to contact the walk board, thus the extra friction.
To check your walk board you can loosen the adjusting bolts on the rear and while lifting the walk board look underneath. If there is any wear/white areas then you will need to replace the board as well. You will be able to tell by just rubbing your hand across it and check for any places where the black film may be coming off.
Also the only time you really need to replace any of the rollers is when the bearings go bad or the pulley on the front roller separates. The rollers are about a 1% chance of causing this problem.
Good Luck! and great question, Tim

PROBLEM: The walking belt is off-center or slips when walked on SOLUTION: a. If the walking belt has shifted to the left, Start unit @ 1.0 mph using the hex key, turn the left idler roller bolt clockwise 1/2 of a turn to move belt to the right. Be careful not to overtighten the walking belt. If the walking belt has shifted to the right, turn the left idler roller bolt counterclockwise or clock wise 1/2 of a turn depends on the tension that will be on the belt take your time and walk on it to feel the belt underneath you
Repeat until the walking belt is centered.
SOURCE: Adjusting the walking belt
Here are two solutions one is to get the belt centered on the treadmill
and the other is to tighten the belt.
There should be two bolts
in the rear of the treadmill, one on each
side. These bolts adjust the rear roller of the treadmill. The walking
belt will always go to the side that is looser. To get the belt back
on track, (if you can start the treadmill so the belt is running)
tighten the bolt on the side that the belt has slipped to. Tighten the
bolt a little bit at a time. If you tighten the bolt too much, then the
belt will go to the other side.
To tighten the belt, start by
locating the two bolts that adjust the
rear roller (one on each side of the unit in the back). Run the unit at
about 3 mph. Tighten the bolts a 1/4 turn at a time. Make sure that
what you do to one side, you MUST do to the other side or the belt will
get off center. After you tighten it 1/4 turn, check the belt to see if
it is still slipping. If it is then tighten the belt 1/4 turn again.
Continue until the belt does not slip, but do not tighten the bolts more
than 2 full turns.

Unplug the unit remove the motor shroud inspect the drive belt if the rubber feel slick then my recommendation is to replace the drive belt. Adjusting the drive belt may take care of the problem if you do not need to adjust it too tight. If you choose to do the adjusting and feel you have adjusted the running belt thinking it would resolve the slipping, then back the tension down until it the running belt is slipping then adjust until the slippage is resolved.
