I was recently informed of price increases for motor control boards for certain models the following brands:

Horizon Fitness, Vision Fitness – Up to $439, I will know based on the model treadmill you own.

Sole Fitness $289.99

The board can be repaired less expensively, however it needs to be shipped out for repair. Lead time could be 2 to 4 weeks for repair. One company I use will expedite the repair for an extra $50 (once they receive it, it goes to the front of the line for repair).
