Replace the LCB, board under the hood of machine. The UCB (Upper control board relays the key information to the LCB.

When the LCB traditionally goes out it cannot reconize the machine is not responding properly. The LCB is what usually sends out the error codes to the display screen.

SOURCE: Athlon iQ2 treadmill-just replaced motor control

If this is the same problem you had prior to replacing the MCB and speed sensor. I would check the drive motor, unplug unit then remove motor shroud then unplug the connectors leading to the motor itself. If you have wire leads and a 18v drill battery connect the leads into motor then attach the other end to you battery and if the motor will rotate ( approx. 1mph) , if it does the check speed sensor to see if the correct spacing between sensor and front roller ( check if the magnet has not fallen out of front roller pulley this also can cause you problems) hope this help!!

SOURCE: Machine shuts off when i press incline up. Belt and board look ok

THis sounds like a controller board problem. In many of the treadmills I have seen the same board controls the drive motor and the incline motor. If this product is under warranty have the company covering the warranty check it out. Anytime you buy one of these machines buy the extenced warranty. I was a field service tech for a warranty company. When you call in with a problem make it sound severe.. I have replace almost everything in one except the frame just to make a customer happy. I am not sure of the error message but i seem to remember it being associated with the controller.

Sportsart treadmill error 7


Treadmill Parts for SportsArt Belts Motor Brushes SPORTSMITH net
ERR7 Definition: The display board main IC didn't receive the incline variable resistor (VR) value, or the value exceeds the set range. Explanation: The incline VR voltage changes as the incline motor operates, and the display board CPU uses the VR voltage to calculate the incline position. Without this value, the CPU cannot instruct the incline motor what to do, so ERR? appears. Or when the incline set is out of alignment, the VR value exceeds the set range.

The following is a list of possible solutions:

1. Incline Set a) Inspect whether the Incline ERR LED on the drive board lights. This LED indicates that the incline set has exceeded the range. b) Inspect whether the incline set mechanically exceeds range. On DC incline motors, at the 0% position, the line on the thin incline pipe will not align with the end of the thick pipe. On AC motors, at the 0% position, the red line will not appear even with the bottom of the incline window in the incline set. See Incline Troubleshooting Manual for details. c) Inspect whether the incline VR voltage exceeds the range: Put multimeter probes on the incline VR set blue and green wire connectors, while keeping the wires connected. Refer to Incline Troubleshooting Manual for the voltage range for your treadmill. If the incline range is exceeded, either mechanically or electronically, calibrate the incline set. Refer to the Incline Calibration in the Incline Troubleshooting Manual for directions. If the incline set cannot be calibrated electronically, replace the incline VA. If the incline set is stuck and cannot be unstuck, replace the whole incline set. 2. Drive Board Inspect incline voltage on the blue and green wires at the drive board. If voltage is within range, and ERRl appears, inspect drive board component connections and components for wear. 3. Ribbon Cable Inspect ribbon cable for breaks. Inspect connections at the display and drive boards. 4. Display Board Inspect IC connections. Push down to secure connections. Re-insert les.

Pro-Form Crosswalk 395 - Incline goes up and down with no tread movement. Calibration doesn't work - only on display.


test the main board, with the output voltage from board for input voltage motor. If there are NOT voltage the board is faulty.replace see the block diagram, how the main boad control about 80% of the machine motion.

Treadmill will incline but not stay up. incline # stays after bed lowers


incline Motor is not working it can be a few different things.
1) may not be any signal from the console which could be a damaged cable(tight the flexible cable from keypanel vs display board)
2) Tight the connector from display board vs lower board ( main motor controller board the console itself has failed.
3) The motor control board may have failed from a worn treadmill belt and deck measure 120VAC input for the board
5) the motor may have burnt out Test try to measure 120VAC.
6) potentiometer geared to the motor adjust it so the console knows what height the incline is at.
7) the gearing can slip, giving the console false information which can cause chassis damage.
Now see the block diagaram that I did , for person like you, for to know how the main motor board has aprox 90% of functions of any treadmills. sincerely. Good luck, G-d bless you.

My proform 360p treadmill is stuck on full incline - can it be fixed and if so how???


try thisSometimes incline motors will get frozen in position and need broke free. Try this:
take the motor cover off and take the screw out of the bottom of the incline motor that is attached to the screw assembly. Once you remove the screw you should be able to break the incline motor free. run the incline up and down with the screw still off( laying the treadmill on its side may make this easier). Once it goes up and down (hold the screw so it goes in and out) reattach it then run the calibration described below. If it was just stuck it should work fine.

1. remove safety key
2. press and hold the speed+ and stop keys at the same time
3. Put the safety key in/on and release the keys
4. press stop once
5. hit the incline + arrow and let the incline go the whole way up and down
6. remove safety key and try

If these instructions do not work to fix the incline motor
check your main harness running down the right leg for breaks in the wires or a loose connection if nothings found you can switch the red and black wires on the incline motor terminal block and see if it goes down. If it does you know you are only getting voltage to one side of the motor. There is a schematic under the motor hood that tells you what the voltage should be when you press the up or down keys. Use a multi-meter to see if you are getting the correct voltage coming from the console to the motor control board and then from the board to the motor. If no voltage from console-replace console if you have voltage from console but not from board - replace board and finally if you have voltage from console and from board replace motor. You will need to test the voltage both when pressing the up key and the down key.

The incline on my proform treadmill is not working and now I can't get the treadmill to start, it just keeps inclining up and down


ICON CALIBRATION INSTRUCTIONS- INCLINE
1) Press the Stop and the Speed Up keys down while inserting the safety key.
2) Press the Stop key one time. The Time window should read EP:2P. Some newer models may also say FP, Pass, or the like. This means that it passes the EPROM test.
3) Press either incline key and the incline will calibrate automatically.
4) THIS IS A VERY IMPORTANT STEP BECAUSE YOU WILL GET AN ERROR MESSAGE IF THIS STEP IS SKIPPED.After completing calibration of incline, press the Stop key and then remove the safety key.



If the incline moves but you it will not operate normally nor calibrate, check the wiring from the incline sensor to the power board. If all looks normal, put it back in calibration and see if you see a blinking “- -” symbol in the incline window when you are calibrating. If not, the incline sensor is bad.

If the incline moves but only just a bit, it could be a problem as simple as the gearbox on the motor being jammed. We remove the motor from the treadmill, reconnect the wiring, and then try to run the incline motor outside the treadmill. Many times, this will unjam it if that is the problem and then reinstalling it in the treadmill will get it to work. If you have the same problem or it doesn’t run outside the machine and you can hear it try to work, you need to replace the incline motor.

If the incline motor does not move, we need to figure out if the motor is getting voltage. Use a simple multi-meter and set it to AC volts. When you put it into calibration, it tries to calibrate the directions one at a time. Measure across the white and black wires first, then measure across the white and red wires second. If the motor is getting voltage you will read 120VAC (or
thereabouts) one one of the measurements. If you have voltage but the motor won't move, you need to replace the motor.
4.
If the incline motor does not move and you have done the voltage test and you do not have any voltage present, there is a problem in the electronics board that supplies the power. If the console is powering the drive motor as normal, you can bet it is getting an incline signal and the power board needs to be replaced (some models have an integrated power board/controller) so if there is only a single board the whole board has to be replaced. It is possible the console is not giving the proper signal but we've never seen it happen in thousands of treadmills.

How do I fix my Endurance Treadmill TF3i Err7 problem? I stopped during operation.


Unplug unit remove motor shroud check connections on lower board (incline board). I believe their is a 3 amp fuse in circuit check with multi meter to see if open replace fuse power up unit and if it blows the fuse then replace incline motor and if not, then use engine mode press stop then Incline + or - to force incline up to max incline then bring it down to 0 then turn off power then wait 10 seconds then hit power on then if error does not appear then hit start and resume using unit. If the procedure above does not activate unit then replace board.

Green lite comes on for about 2 to 3 seconds then shuts down red lite pulses


If the back was off the board on the left is your Ysus board. It will have a cable plugged into the right side of the board from the signal board. Unplug the the Ysus board. If it stays on without a picture change both Y and Z sustain boards. If this helps let me know.
