Tornado EB 30/1 Complete Electronics K46820920

The complete electronics (part# K46820920) is the control board of the Tornado EB 30/1 electric broom. It sits between the battery pack, the on/off switch and the brush motor, and it manages the charging circuit and the motor supply. On a battery machine this board is the part that decides whether anything happens at all when the switch is pressed.

Faults that point at the board

Board failures tend to be binary rather than gradual. The machine does nothing when switched on although the battery is charged; it runs only intermittently, cutting in and out without the switch being touched; it will not accept charge even with a charger proved good on another machine; or it runs at a fixed speed and ignores the switch entirely. A burnt smell or visible scorching on the board is conclusive.

Because those symptoms overlap with a flat battery, a failed charger and a broken switch, work through the cheap items first. Confirm the pack holds charge, confirm the charger delivers, and check the switch (part# K66304130) for continuity before replacing the board. Most no-start complaints on these brooms turn out to be one of those three rather than the electronics.

Fitting note

The board is supplied complete. Note the orientation and connector positions before disconnecting the old one — a board fitted the right way round but with two connectors swapped behaves exactly like a dead board.

Frequently Asked Questions

What does the complete electronics board do on the Tornado EB 30/1?

It is the control board between the battery pack, the on/off switch and the brush motor. It manages the charging circuit and the motor supply, so nothing happens when the switch is pressed unless the board is working.

How do I know if the electronics board has failed?

Board faults are usually all-or-nothing: no response at all with a charged battery, cutting in and out without touching the switch, refusing to accept charge from a charger proved good elsewhere, or running at a fixed speed regardless of the switch. Visible scorching or a burnt smell confirms it.

What should I check before replacing the board?

The three cheaper causes with the same symptoms — that the battery pack holds charge, that the charger actually delivers, and that the switch (part# K66304130) has continuity. Most no-start faults on these brooms are one of those rather than the electronics.
