Tornado Strike Parking Position Sensor with TVS Diode K41011190-R

The Parking Position Sensor (part# K41011190-R) tells the Tornado Strike TV190-W10-U whether it is standing upright or reclined for use. The -R suffix is Tacony’s reworked version, supplied with a TVS diode fitted to protect it from voltage spikes — a change made because the earlier part was vulnerable to exactly that.

Compatible Models for the Parking Position Sensor with TVS Diode

• Tornado Strike Cordless Upright Vacuum — Model TV190-W10-U

This is a Strike-only component: Tacony’s parts records list the Tornado Strike TV190-W10-U as the single machine that takes part# K41011190-R, so there is no cross-model substitution to worry about when you order it.

What the Parking Position Sensor with TVS Diode does

The sensor reads the magnet in the base of the machine and reports the result to the motherboard. That single piece of information governs the brush motor: reclined means the brush is allowed to run, upright means it must not. It is what stops a brush roll spinning against carpet while the machine is parked, which is how carpets get burned and brush motors get cooked.

Signs the Parking Position Sensor with TVS Diode needs replacing

The signature fault is a brush roll that will not spin when the machine is reclined, while suction works perfectly. The mirror image — a brush that keeps running when the machine is stood upright — is the other one, and it is the more urgent of the two. Before ordering, check the magnet assembly in the base (part# K41011180) and the sensor cable (part# K66519020), since both produce the same symptom for far less money.

Fitting the Parking Position Sensor with TVS Diode

Disconnect the battery and leave it out. The sensor is positioned relative to the magnet, so note exactly how it sits and how its cable is routed before removing it — a sensor mounted a few millimetres out reads unreliably and produces intermittent faults that are worse to diagnose than a clean failure. Fit the replacement in the same position, reconnect at the connector, and test by reclining and raising the machine several times to confirm the brush starts and stops as it should.

Twin City Vacuum has been selling and servicing Tornado equipment since 1956. You can browse the rest of the machine on our Tornado Strike parts pages, and the manufacturer publishes specifications at tornadovac.com.

Frequently Asked Questions

My brush will not spin but suction is fine. Is this the part?

It is a likely candidate, but check the cheaper things first: the sensor cable (part# K66519020) and the magnet assembly in the base (part# K41011180) both produce exactly this symptom, and between them they cost a small fraction of the sensor.

What does the -R in the part number mean?

It marks Tacony’s reworked version, which is supplied with a TVS diode fitted to protect the sensor from voltage transients. It is the current part for this machine.

The brush keeps running when the machine is upright. Is that dangerous?

It is worth stopping the machine over. A brush roll spinning against carpet in one spot will mark or burn it, and the brush motor is working against a load it was not meant to see. Take the machine out of service until the sensing is right.
