Beam Q100 Power Nozzle Main Circuit Board D1 Once the electrical path is

Once the electrical path is compromised

It provides the primary control that turns the vacuum on and off and carries the machine's operating current

This assembly is the interlock that holds the filter cover closed and secured whenever the vacuum is in use

Carbon brushes are wear items that transfer electrical current to the motor armature

Fitting a fresh bag restores full airflow and filtration

Beam Q100 Power Nozzle Main Circuit Board D1 Once the electrical path isThis replacement main circuit board (part #100427) is the control board for the Beam Q100 power nozzle. The board manages power to the nozzle's brush roll motor and its control functions. When the main board fails, the power nozzle may not start, may run erratically, or may stop responding to its controls. Electrical faults on the board can mimic a failed motor. A correct board restores proper control and reliable operation of the nozzle, and
