Horizon treadmill won't incline

The issue you are experiencing with the incline motor on your Horizon Quantum II treadmill could be caused by a variety of factors, including a problem with the motor itself, the control board, or the wiring. Here are a few steps you can try to troubleshoot the problem:

1. Check the motor: As you mentioned, you were able to operate the motor when 230V was applied, which suggests that the motor itself may be functioning properly. However, you may want to test the motor further to confirm that it is not the cause of the issue.
2. Check the control board: The control board is responsible for controlling the incline motor, as well as other components of the treadmill. If the control board is damaged or malfunctioning, it could be causing the issue you are experiencing. Test the board to see if it is functioning properly.
3. Check the wiring: The wiring between the control board and the incline motor may be damaged or malfunctioning, which could be causing the issue. Check the wiring for any visible damage or loose connections, and test it to see if it is functioning properly.

If you are unable to troubleshoot the issue using the steps above, or if you are not comfortable working with electronic components, it is recommended to seek the assistance of a qualified technician to diagnose and repair the treadmill.

E6 or E7 An E6 or E7 error code is an incline error code. The E7 code means the potentiometer value the console is reading from the lift motor is out of range. This can happen when there is a bad wire harness connection or a damaged wire harness. It could also just mean the incline motor needs to be adjusted back into range. If all wire connections look ok, the incline motor will need to be adjusted.

1. Turn the power OFF, wait 5-seconds and turn back ON.
2. Get into test mode and enter through the I/O testing step. This screen will display the potentiometer value of the incline motor. Different models will have different values. Check to see if the running deck is raised to high incline level or if it is at the low level. If the running deck is at a low position press the incline up button. This will cause the incline motor to raise the running deck up. When the deck gets to a mid-level position, press the incline up button a second time to stop the deck. If the running deck is in a high incline position, use the incline down button to adjust the deck to a mid-level position.
3. Once the unit is in the mid-level position, power the treadmill off for 5-seconds and then power it back ON.
4. Start the treadmill.
5. Once the treadmill starts the running deck will move to the level 0 position. If this does not resolve the issue or it will not adjust please contact customer service.

Also note that not all models will have the ability to adjust the incline motor. If the adjustment procedure is not found in the Owner's Manual then contact customer service.

hi, i also have problem with my horizon htm 3000, incline motor stuck.
did anyone know where to buy brand new incline motor?
and how much it will cost?

This may be the controller .

please see the video and proceed according, LUBE the rollers bearing very IMPORTANT!
However , if the problem persist your must test a) main motor+belt
b) main control motor board see the block diagram attached.
God bless you

Step 1:

please see the video and lube too the rollers bearing. Happy new year and God bless you

Step 2:

test the input voltage motor, if there are voltage in the motor, the motor NEED repair, see the diagram attached, and see my personal TIPS for motor help.

Step 3:

test the output voltage board, for input voltage motor, if there are NOT the board is faulty.
see the diagram attached.

see the diagram attached and test test the input motor voltage, if there are the motor is faulty.see my personal TIPS.
God bless you

1)signal false coming console or display board
2) main motor controller is faulty.
3)Pot attached of the elevation motor ,need adjustment
4) geared slip from elevation motor , carring false signal to console.
Proceed to Test it.

For the Fitnex T30 treadmill, the error 7 (listed err7 on the display) code means that there is a fault with the incline motor. My problem was the incline motor had burned out probably from usage, and during my research, this seems to be a weakness for the T30 model. You can remove the front plastic cover, unscrewing the 4 phillips head screws to reveal the electronics board, belt motor, and incline motor. With the power on (do not touch the board or wires 'cuz you could be electrocuted) check the board located next to the power switch. If the board's two lights are lit green, then your incline motor has probably ceased to live. Just in case, make sure to check with a flashlight, all those capacitors. One of them could have blown out and I'm not sure whether the green lights would indicate that. If one is blown the cylinder end will be bulged as if the cylinder 'popped'. You can see that the cylinders are stamped with a plus-sign. This is a built-in weakspot to allow an 'explosion' to puff out that plus-sign stamp. It will be fairly obvious if one has kaboomed. Make sure the wires are intact as well. Use a dustsprayer to blast all the grime and dust off the board and wires and motors. If all looks good, it's probably your incline motor itself that has gone kaput. Now let's get that motor out! Turn off the power and remove the power pIug from the outlet! First, I removed the grounding screw (green wire), unplugged the 4 prong main switch and 3 prong secondary switch from the motherboard that connect to the incline motor. [Just a footnote, inspect the connections of those wires into the incline motor just to be sure. If all is well, continue motor removal]. Next, use wrenches to remove the top nut and bolt securing the incline motor. Then, gently tip the entire treadmill on its side and do the same to remove the nut and bolt from the incline bar across the bottom of the treadmill. Now flip the treadmill rightside up. Remove the incline motor. I ordered the same motor, used and rebuilt, from sbarker (Ebay id), sbarker10 (Amazon id) for $54, shipping included. You're not going to get a better deal than that. A new replacement motor from a exercise equipment store online wanted $200 which is just not worth it. From order to arrival, took 4 days. Follow the same procedure in reverse order to install your new motor. Everything should work fine. If you're still getting the error than there must be a wiring issue between your board and the incline motor, or the board itself is faulty, but then that's beyond my knowledge of this particular problem. Don't worry though, with what I've found, the incline motors are poo-built, so if you're getting this error in the first place, I'd bet the farm it's a burnt incline motor. Good luck
