Most of the motor control boards can be repaired. These boards send the control the speed of your treadmill. If you ever “Start” your treadmill and the display shows it’s working, but the belt isn’t moving, then your control board most likely failed. Most of these can be repaired. Be prepared for down some if it needs to be sent out. Once sent for repair, it’s out of my hands to the repair company. Depending on how busy they are, it could be a week and half, and lately I’ve had up to 4 weeks before I get it back. I will check status of the repair with the companies. Some are faster than others. Depending on your treadmill brand, a rebuilt board may be available to purchase, and may save both time and money.
This also applies to consoles sent for repair. The only consoles that really cannot be repaired if they completely fail are the residential ones (Nordic Track, ProForm). I haven’t found anyone that can actually fix these, especially the newer ones with the tablet screens. There are some things I can try and have been successful with depending on the symptom. Buttons beeping, but not responding, and the screen stuck in a loop are a couple of them. Most commercial consoles can be repaired.
