Stop button, fan button, up incline button are not working on proform 530. do these buttons have something in common?? fixable without a new console??

If you've already replaced the lift motor on your Proform 400s Treadmill and the incline still won't work properly, there may be other underlying issues that need to be addressed. Here are a few troubleshooting steps you can try:
Check the wiring: Ensure that all the wiring connections related to the incline mechanism are secure and properly connected. Loose or damaged wiring can cause issues with the incline functionality.
Inspect the incline motor and gears: Examine the incline motor and gears for any signs of damage, misalignment, or obstruction. Ensure that the gears are engaging properly and that there are no obstructions preventing the incline from moving up and down smoothly.
Reset the treadmill: Perform a full system reset on your treadmill. This can often resolve minor software glitches or issues that may be affecting the incline function. Consult your treadmill's user manual for instructions on how to perform a reset.
Contact customer support: If you have followed the above steps and the issue persists, it is recommended to reach out to the customer support of Proform or the retailer from whom you purchased the treadmill. They should be able to provide further troubleshooting guidance or arrange for professional repair assistance if needed.
Remember to exercise caution when working with electrical components or performing any repairs on your treadmill. If you are unsure or uncomfortable with the process, it is advisable to seek assistance from a qualified technician or the manufacturer's customer support to ensure proper diagnosis and resolution of the issue.

If you can get in behind the buttons, clean them with electrical Contact Cleaner spray. Also clean the connectors with it as well.

A power reset is the only help given. One article suggests a factory reset for 3 or 4 beeps.

Calibrating Your Incline Is your incline not operating correctly? There are a few simple steps that can be followed which will most likely resolve that problem for you.

The first step is to press and hold both the STOP and SPEED INCREASE buttons, this will be either an UP ARROW or a + (plus) symbol. While holding these two buttons down you will need to insert your safety key.
Once you have inserted the safety key you can release the buttons and let go of the key. At this point you will need to press the STOP button one time. Congratulations, you are now in Calibration Mode.
Now that we are in calibration, press the INCLINE UP button one time. This will cause the platform to go all the way up and then it will come all the way back down again.
Now that the incline has stopped moving you can remove the safety key.

I have a Proform ZT5 model - had the same incline/decline problem. It needed calibrated.
- unplug, turn off, and take the key out
- plug machine in
- turn switch on
- Pres and hold the STOP and SPEED UP button at the same time, while holding them insert the RED KEY
- let go of both buttons
- press STOP 1 time
- pres INCLINE UP 1 time
- this should reset it.

The tech on the phone mentioned the importance of turning the maching off, taking the key out, and unplugging after each use. Leaving it plugged in there is still an electrical current running and this can cause more seriouc problems that require a new control panel.

Try to calibrate the incline: Hold down the stop and speed up buttons at the same time then insert the key. release the buttons the press the stop button and release then press the incline up button. the incline motor should go all the way up then all the way down with - - on the console. If the unit only moves just a and inch or so or the motor just hums , the incline sensor is faulty.

If it lights up, incline works and counts like it's going but no belt movement it's your motor controller. If it's not doing these things then I need to know what it's doing or not doing.

I had the same problem-only one of my programs would work, and the rest of the buttons (even start) would not work. I used some scissors and carefully cut about a 1/2 inch in the plastic inbetween each of the copper strips in the ribbon cable. Then I seated each one individually (put them back in the white plastic thing) until I found the one that was freezing all of the other buttons up. Now all of my buttons EXCEPT for the one that was working before work. I can live without 1 program if it saves me $300

PS-mine also stopped working after we moved it, but when I told an "expert" that he said it wouldn't just stop working because I moved it....I think moving it DEFINATELY had something to do with it.

Do a Calibration on the treadmill. Take out the safety key. With 2 fingers, hold down the stop button and the speed up or spped plus button. keep holding them down as you insert the safety key, then let go of both.
Press the stop button 1 time, you should see all 0's in the windows, or EP 2P or something weird like that.
Press the Incline up button and then wait. If the incline go up until it stalls then down until it stalls the stops at the bottom, the you are recalibrated, take out the safery key and put it back in to see if all is well. If the incline takes off up again without touching a button, the you have wiring problems or control problems. Call service company to get it repaired.
