VacuFlo PC/Relay Board for ...
$135.99
Product details
This is the genuine VacuFlo PC/relay board (Part #8173-01), a combined control-and-switching board for central vacuum power units. It pairs the printed circuit logic with the relay that handles the high-current motor load, so a single board failure can stop the entire system from running.
Designed for 240V/220V power units, this board is the correct replacement when your built-in vacuum will not start, hums without spinning, or fails to respond to the inlet valves. Installing a new board restores normal operation without replacing the whole motor unit.
Confirmed fitment:
- VacuFlo model FC1550
- Dirt Devil central vacuum 1099e, 1490, CV3200 and CV3400
- MCE-22D variant (240V / 220V)
This is a 240V part — confirm your power unit's voltage before ordering. Disconnect all power before servicing.
