Maintenance Tips for AirMaster

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 AirMaster 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 AirMaster 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

AirMaster 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 AirMaster 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. Choose the correct board from 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 AirMaster to see our recommended circuit board. The most common board replacement for AirMaster Central Vacuums is the Vacuum Motor Circuit Board for Single Motor Units 110 Volt. The board is strong yet generic, and may need to be retrofitted. 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.
