In such cases, it is recommended to seek professional assistance from a qualified technician who can accurately diagnose and repair the motor or advise on the best course of action to resolve the issue.

If the voltage output test is successful, proceed to the next step to test the motor for resistance.

 

Step 5: Testing for Motor Resistance

Testing the motor’s resistance can provide valuable information about its internal components and overall health. Resistance testing helps determine if the motor’s windings are intact and functioning properly.

To begin the resistance test, ensure that the treadmill is unplugged and disconnected from the power source. Set the multimeter to the resistance mode, typically indicated by the Ω symbol.

Locate the motor’s power terminals and remove any wires connected to them. Place one multimeter probe on one terminal and the other probe on the other terminal. The multimeter will measure the resistance of the motor.

A normal range for a treadmill motor’s resistance can vary depending on its size and specifications. Consult your treadmill’s manual or contact the manufacturer to determine the expected resistance range for your specific motor.

If the resistance measurement falls within the expected range, it indicates that the motor’s windings are intact and functioning properly. This suggests that the internal electrical components of the motor are in good condition.

However, if the resistance reading is significantly higher or lower than the expected range, it could indicate a problem with the motor’s windings, such as a short circuit or an open circuit. In such cases, it is highly recommended to contact a professional technician who has the expertise to diagnose and repair motor issues.
