20 Most Recent Nordic Track NordicTrack Treadmill, A2550 Questions & Answers

hi,
You have to check the Driver circuit board for the motor. There is motor control IGBT Insulated Gate Bipolar Transistor) in this board .If the IGBT is short then the treadmill will try to run without setting any value or witout pressing the start button. You have to check the OHMS between the seocnd and third of lead of the IGBT. If it shows less than 100 Ohms then the IGBT is short and you have to replace the same. Also you have to check the connection to the control pannel. Is there is any loose conatct. Remove the connection in the motor control board which go to the control pannel and reconnect it. Also check the speed sensor. In most of the treadmill you can find the speed sensor near the motor pully. Remove the speed sensor and clean it and the refix it. Remember one thing remove the power of the treadmill and leave it for 30 minutes then only oppen the treadmill. Because there is high voltage storage capacitors in the motor control board which will hold charge for some time even after the power is disconnected. i ahve added the picture of IGBT for your refference
ok

I have a NordicTrack C2155. Incline not working. There is a schematic inside. There are red, white, & black wires from the circuit board to the incline motor. Unplug the treadmill and have a licensed electrician construct a flying lead cord with a male spade on neutral and female spade plug on hot. Connect neutral to white and hot to where either red or black were connected. Plug in to see if the motor runs. Careful to remove power when the incline reaches its limit and reverse direction. If the motor runs in both directions, the motor is good. Follow the black two conductor wire to the circuit board and unplug from board. Check continuity across this switch. Run motor and this should toggle off and on. If all this checks out then the problem must be with the circuit board. On my treadmill, the schematic says that +5v should supply the sensor, but I only get +3.3v, which is TTL level. The drive motor sensor supply is +5v. The incline motor doesn't even show a sign of trying to run. Either the output transistor is burnt out or the low voltage caused an error so that it does not try to run the motor. Either way, I'm quite certain that a new controller board will remedy the problem.

it is trying to calibrate itself, let it go the whole way up and then down without interrupting it. Then it should be fine.

the motor controller is bad and needs replaced

my nordic track 1000 stops several times during the workout. I can step to the side and the belt may or may not start back up. The display continues to display the set machine. any suggestions?

Mi caminadora nordictrac apex c500 marca el error checksum: fail, alguien sabe como arreglarlo?

Probably 85% of the time, it's the sensor.



1. remove the screws from the bottom of the enclosure case. 2 or 3 in the front and 1 on each side

lay it back down, and power it up, and actuate your incline. watch the end of the motor, to see if the shaft is moving. It probably IS turning but only a little bit. NOT enough. In this case I'd say it is the sensor.

2. Unplug the unit of course.
3. the incline motor is in the middle of the pack,..you'll see a black tube looking thing sticking up.
4. on the bottom side of this, you will see,..or feel for a black square sensor attached to bottom of the motor casing.
5. follow the wires and unplug this.
6. pry it off with a screw driver. Remove incline assembly, if you cannot reach it.
7. replace sensor and try it again.

if the MOTOR does NOT turn when using the incline buttons, the problem backs up to possibly a bad control board. or a bad motor on your incliner, however, i'd say that's the last thing to go.

Order of failure: 1. sensor 2. control board 3. motor.

good luck

Got beeping? I JUST figured out how to fix it. Take the console apart and pull the connector from the back of the iFit card adapter. Plug back in, should be good as new!

All, just figured something out. I had the evil beeping problem as well. I decided to play around and see if I could fix it. I unplugged the iFit adapter from the main control board and when I plugged it back in and tested it, IT WORKS AGAIN! NO MORE BEEPING!

A) HOW TO LOWER THE TREADMILL FOR USE

1. Refer to drawing 2 above. Hold the upper end of the treadmill with your right hand as shown. Using your left

hand, pull the lock knob to the left and hold it. Pivot the treadmill down until the frame is past the pin on the lock

knob. Note: You may need to push the handrail to the side slightly.

2. Refer to drawing 1 above. Hold the treadmill firmly with both hands, and lower the treadmill Watch thsi video:http://www.youtube.com/watch?v=kDNegYEnrSc

Before folding the treadmill, adjust the incline to the

lowest position. If this is not done, the treadmill may be permanently

damaged. Remove the key and unplug the power

cord.

1. Hold the treadmill with your hands in the locations shown

at the right.

Raise the treadmill about halfway

to the vertical position.

2. Move your right hand to the position shown and hold the

I have the same issue I don't think anybody (including the supposed "experts") really know what they are talking about. The buttons work until they don't and then a bunch of them all stop functioning at once. The advice I always get is "replace the console" which amounts to saying "I don't know what's wrong" If I had to guess I think a static discharge has damaged the contoller board which doesn't manifest itself until the machine (and hence the board) warms up. Anyhow I haven't found a real solution to this issue if anyone has any real knowledge please post your solution.

1. Power

o 1

Ensure that the treadmill is plugged into a grounded outlet using the correct surge suppressor. Use a UL 1449 suppressor listed as a transient voltage surge suppressor (TVSS). It must be rated for 15 amps and 120 volts AC. Secure the services of an electrician if the outlet is not grounded, or move the Proform treadmill near a grounded outlet. Do not use an extension cord.

o 2

Insert the safety key fully into the display. Treadmills with keys are designed not to turn on without the safety key in place.

o 3

Find the circuit breaker on the front of the frame and make sure it is not tripped. The circuit breaker is a vertical switch on the 540S and a horizontal switch on the 540 Interactive Trainer. Press it to the "Reset" position, which will be labeled. 2. Reed Switch

o 1

Unplug the treadmill and remove the safety key.

o 2

Move the upright base of the treadmill down with the help of another person and lift the uprights so that you can get to the underside of the console. Use a Phillips screwdriver with at least a 5-inch shaft to remove the screws. There are five hood screws on the 540 Interactive trainer and four screws on the 540S.

o 3

Remove the motor hood to get to the small reed switch by pivoting the hood off the frame. Find the reed switch and magnet, which are on the left side of the pulley for both models.

o 4

Turn the pulley with your hand until the reed switch aligns with the magnet. There should be 1/8-inch gap between the two. Fix the distance so that it is 1/8 inch by loosening the reed switch screw and sliding it to the correct distance. Tighten the screw.

o 5

Reverse the directions to put the hood back on and the treadmill upright in the original position.Cleaning: Remove the covert and spray the Key Pad with special spray( contact cleaner) for to remove dust, etc, very carefully, you mus unplugged the machine.

Dear Sir:

Thank by your request, I hope everything is o.k
I will try to help you, inmediately.

1)
Pedal Arms
1
Use aflat screwdriver to unseat the tabs that hold the front top cover in place. Thiswill expose the flywheel and pedal arm connection points. Rotate the flywheelby hand and determine whether lubrication will accomplish the repairs. If thebearings are exposed, use a grease gun with an extension nozzle and lubricateboth bearings with lithium grease. If the bearings are damaged or sealed,proceed to the next step.2
Removethe front and side covers on the main frame. Hold the flywheel with one handand use a box wrench to loosen the bolts that secure the pedal arms at eachside of the flywheel. Pull the arms away from the flywheel and remove thebearings from each side.3
Test thebearings as before. Lubricate exposed bearings with lithium grease andreinstall them. Sealed bearings must be replaced. Reattach the pedal arms tothe flywheel. Replace the main frame covers and front top cover to complete therepairs.
If you need further assistance, please reach me.

Thank you in advance, sincerely. God bless you.

Not helpful to your question except that I have the same problem. My issue occurred after it was moved up some stairs, possibly misaligning something??? I have the drive hood off and am trying to follow suggestions to reset/calibrate the reed switch--but no change to the problem.

I had the same problem with my Nordic track. I pressed every button until I found the one that did not beep. The one that does not beep is stuck. My problem was with the Ifit button. The first few times I would push the bad button until it started beeping. That worked for awhile (couple of weeks but started up again). I disconnected the Ifit unit and now the thing work fine except for Ifit which I never used. Nordic track wanted to sell me a new console which cost more than the machine.

Please download the instruction manual and follow the steps. Blessing. [email protected] cell+whatsAPP:+50588611441 Free Treadmill User Manuals ManualsOnline com

It probably has to do with the belt overheating the motor and irritating your controller. Try replacing the walking belt.
