A commercial treadmill consistently draws higher amperage than specified. Your first diagnostic step should be:
- AImmediately replace the motor control board
- BVerify input line voltage and then check the running belt for excessive friction or binding
- CInspect only the incline motor and wiring
- DRecalibrate the heart rate sensor system
Correct Answer
Verify input line voltage and then check the running belt for excessive friction or binding
Explanation
High amperage draw means the motor is working harder than it should. First verify the supply voltage is correct (low voltage causes motors to draw more current), then check belt/deck friction as the most common mechanical cause.
