If the problem is in the drive belt, either the drive belt will stop when stalled or the front roller will stop when stalled. Follow this procedure: First remove the key and UNPLUG THE POWER CORD. remove motor shroud, then find the motor mounts. Many motors in Icon treadmills have a main pivot joint in which a bolt runs the full length of the motor mount. This bolt will require loosening to provide maximum adjustability.
If your treadmill is not equipped with a bolt as described above, the drive belt must be tensioned by hand. While one person applied increased tension to the drive belt, the other person should tighten the motor set bolt Tighten the bolt and test. If the problem is not corrected, repeat steps above and retest.
If the motor, drive belt, and front roller continue to turn when the walking belt is stalled, the problem is with the walking belt slipping on the front roller. Follow this procedure:
First remove the key and UNPLUG THE POWER CORD. Using the allen wrench, turn both rear roller adjustment bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the power cord, insert the key and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened. Rear Roller Adjustment Bolts

If the drive belt continues to turn but the front roller stalls, you may have a broken front roller pulley and front roller must be replaced.
Follow this procedure: First remove the key and UNPLUG THE POWER CORD. remove motor shroud. Loosen the rear roller and remove the two adjustment bolts. Some models have a spring loaded tensioner on the right hand side so be careful when removing these bolts. After the bolts have been removed, remove the rear roller end cap(s). The rear roller should now simply slide out of the walking belt.
Remove the motor hood. Using a black permanent marker, make a mark on the front roller adjustment bolt on the motor compartment side at exactly where it fits flush with the roller so you will know where to retighten it later. The adjustment bolt is on the right hand side of the front roller. Then remove the bolt with a 7/16” wrench. then remove front roller and replace with new reverse procedure mentioned above

How to fix "The equipment is blocked (com)" error on technogym treadmill's display?

Equipment is blocked can be a number of things.

Not sure what MOSFET is.

First, and usually the most popular thing is the electronics.
Other usual things to look at:
-the emergency stop can be malfunctioning. Does it move or is it fixed still? That's something I just had to repair on a treadmill recently.
-A cable could be loose. Try taking a Cat 5 cable from the lower kit directly up to the display and see if that does anything. This isn't a common issue, but worth a shot.

The resistance belt on my nordictrack 1300 woulnt tighten. How do I fix it? Thanks for you assistance.

When using the NordicTrack in manualmode, you can adjust its resistance by twisting a resistance knob, locatedeither in the corner of the console or on the upright support. If the treadmillbelt slips from side to side, you need to adjust its tension via bolts locatedin the back of the machine frame. First find the treadmill adjustmentbolts in the rear end of the treadmill frame, to either side of the belt. Now putin an Allen wrench into each bolt, one at a time, and turn each bolt aquarter-turn clockwise. Slip one hand among the belt and the treadmill deck. Ifthis doesn't pull the treadmill belt taut, it's still too loose. Tighten thebolts another quarter-turn. Continue testing the belt tension, then adjustingthe bolts as needed, until the belt is just loose enough for you to slip yourhand between it and the deck with no extra slack. Step onto the treadmill andwalk. The belt shouldn't bind or slip side to side. If it does, dismount andre-adjust the bolts until the belt tracks correctly. AV

Hey we moved my treadclimber tc5000 and now it won't power on. Cord is plugged in and outlet is good

there could be several reasons why but i think that you have bumped a wire loose somewhere else. look and see on the control board that wires havent come loose. also check the wires from the console down to the control board. i have fixed several treadmils from people complaining about this same problem.
