Future Motion's GT/GTS boards are self-balancing devices where sensor reliability directly affects safety. If you're troubleshooting footpad sensor "ghosting," prioritize rider safety: a faulty sensor can cause unintended activation or unpredictable behavior.
Repairs may involve replacing the front footpad/sensor assembly, inspecting connector pins, and verifying the controller sees stable input. Because these boards are expensive, a single targeted repair can be worthwhile-especially early in ownership-if it restores consistent engagement and disengagement.
Replacement becomes more compelling when the board is older, the battery has noticeable range drop, or you're stacking issues (sensor plus controller plus battery). Also factor in warranty status and whether the failure mode is intermittent; intermittent problems can be hard to validate, so if the repair can't be confidently confirmed, replacing the suspect assembly may be the safest route even if it approaches the threshold.
