    What to do if my Sunny Elliptical Trainer motor doesn’t work?

      Ryan EvansAug 2, 2025
      If the motor of your Sunny Elliptical Trainer isn’t working, it could be due to several reasons. First, check if the motor wires are properly plugged in or if the motor is stuck; if so, plug the cable in again or consider changing the motor. Another potential cause is an issue with the cables themselves, in which case you should change the cables or plug them in again. Finally, the computer may not be supplying the correct voltage to the motor, requiring a computer replacement.

      Mary GutierrezAug 18, 2025
      If your Sunny Elliptical Trainer displays an E2 error, it indicates a bad connection with the EEPROM. This could be due to an incorrect connection between the EEPROM and IC. To resolve this, remove the IC and plug it in again. Alternatively, the EEPROM data might be damaged, or the IC could be defective. In this case, rewrite the software to the EEPROM or replace the IC.
