Product details
Part B338-3300 is the main circuit board for the straight-suction versions of the Riccar Prima and Simplicity Wonder canister vacuums, in the variant built for variable speed control. The board reads the speed control input and regulates power to the suction motor, so it sits behind the entire speed range rather than one isolated function.
Straight-suction canisters are the models that run a non-electric hose, which is why this board differs from the electric-hose version. Check which hose your canister takes before ordering.
