Treadmill Belt Hesitates Under Weight

Answer: Weak output capacitors sag voltage. UpFix recaps with 105 °C parts and burn-in tests at 60 A for solid torque.

Quick take: Voltage sag from tired capacitors means the motor can’t maintain torque when a runner steps on.

Simple test

Watch console lights as someone runs do they dim with each footfall? That’s capacitor sag.
