Maintenance Tips for Zenex

Motor Replacement Tips

  • Dying motors just stop, but can randomly work.
  • Motor is usually dead if you only hear a click or smell electrical.
  • Motor replacement instructions here. Skill level medium.
  • Find a replacement motor using the model search below.

Only hear a "click" at the motor when trying to start the Zenex system? Or, does it shut off and start back up in a few minutes? These are common signs of a dead motor, which leaves two options: replace the motor or replace the unit. If you liked the amount of suction the Zenex model had, then replace the motor using the information above. If you'd like stronger suction, or a cleaner disposal system, then consider a different unit or alternative brand from MD Vacuum. Our units are Assembled in the USA with the finest materials and backed with excellent customer service.


Circuit Board, Relay, Transformer, MiniBreaker

Zenex Circuit Board Replacement

All central vacuums have transitioned to an all-in-one control board. They no longer use (and rarely supply) replacement individual relays, transformers, and mini breakers. If your Zenex Central Vacuum needs a new relay, transformer, mini breaker, or even a new control board or circuit board, use one of these powerful, durable, cost-saving central vacuum circuit boards. The reality is, a central vacuum really only requires a motor and one circuit board. Some models have a couple of boards or fuses and multiple components that appear to be important, but they can usually all be removed and replaced with a single circuit board. It is not terribly difficult to retrofit a circuit board. An electrician can do it in under an hour.

To find the circuit board you need, verify the number of motors in your unit and the amperage requirements. The most common board replacement for Zenex Vacuums is the Vacuum Motor Circuit Board for Single Motor Units 110 Volt and it may need to be retrofitted. For other voltages and motor configurations choose one of these Durable Generic Circuit Boards made by the industry leading manufacturer. Or, use your model number and the Motor Replacement Parts Chart for Zenex to see our recommended circuit board. There are other Generic Circuit Boards for units with different voltage and multiple motors. Print and use the large photograph of the board as the wiring guide.
