This 120-volt central vacuum control board (Part #235S18) is the replacement circuit board for MD Manufacturing and HAH single-motor power units. It carries the low-voltage logic that senses an open wall inlet or remote keypad and switches the central vacuum motor on and off.
It fits a broad lineup of MD-built power units, including AirMaster, Flo-Master, Modern Day, and Silent Master models such as the F650T, A650TV, CV300, APX, and APXPRO. Please note this 120V board does not fit the APXPROMAX, which uses a different higher-current board. Replace this board when the unit will not start, runs intermittently, or stops responding to the hose handle.
- Fits: MD AirMaster, Flo-Master, Modern Day, Silent Master F650T, A650TV, CV300, APX, APXPRO
- Voltage: 120V single-motor units
- Does NOT fit: APXPROMAX
- Function: Low-voltage motor on/off control from inlets and remotes
A precise replacement board to restore reliable operation to compatible 120-volt MD central vacuum power units.
