Tornado Control Module 19315

Part number 19315 is a genuine OEM control module for the Marathon 800 and Marathon 1200 extractors. The Marathon range used more than one module across its production life and they are not interchangeable, so the first thing to do is read the number off the board in your machine rather than ordering from the model number alone.

Compatible Models for the Control Module

This part fits the following Tornado machines:

• Tornado 98166 20″ Marathon 800 Carpet Extractor (8 Gallon, 115V)
• Tornado 98167 20″ Marathon 800 Carpet Extractor (8 Gallon, 230V)
• Tornado 98168 12 Gallon Self Contained Carpet Extractor
• Tornado 98168 20″ Marathon 1200 Carpet Extractor (12 Gallon, 115V) — all series
• Tornado 98169 20″ Marathon 1200 Carpet Extractor (12 Gallon, 230V)

That warning is the most useful thing on this page. A module that looks identical and plugs into the same connectors can still be wrong for your machine, and an incorrect board is at best a function that does not work and at worst damage to what it drives. If the number on your old module is unreadable — and they do get obscured by corrosion — photograph the board and the machine data plate and call us on 763-535-0770 before ordering.

The symptoms that point to a module are selective ones: the brush will not start but the vacuum runs, or the pump is dead while the rest of the machine works normally. Everything failing together points at the supply, the cord, the strain relief or the main switch instead, and all of those are cheaper.

Check the connectors before the board. A corroded terminal on the affected circuit gives an identical fault for a few dollars. Unplug each connector on that circuit and look inside: bright springy terminals are healthy, dull or crusted ones are not, and insulation that has gone brown behind a lug has been running hot.

If you are replacing a module that failed, find out why. Water reaching the enclosure through a perished seal or a crack is the commonest cause on a machine that carries two tanks over live wiring. Heat from a motor drawing high current — a seized bearing, a dragging brush — is the second. Fitting a new board without addressing either means doing it again.

Fit with the machine unplugged at the wall, photograph every connector first, seat each plug until it latches, keep the harness clear of the vacuum motor housing, and test each function on its own before the machine goes back to work.

Note on availability: we are not able to show a firm price for this module on the page. Call us with your model, serial number and the number off the old board and we will confirm cost and lead time before you commit.

Frequently Asked Questions

What Tornado machines does the control module 19315 fit?

It is used on the Tornado 98166 and 98167 20″ Marathon 800 carpet extractors, the Tornado 98168 12 Gallon Self Contained extractor and the 98168 20″ Marathon 1200 in all series. The range used more than one module, so read the number off your old board before ordering.

My old module number is unreadable — what now?

Do not order from the model number alone. Photograph the board and the machine data plate and call 763-535-0770. A module that looks identical and plugs into the same connectors can still be the wrong one, and an incorrect board is at best a function that does not work and at worst damage to what it drives.

What symptoms point to the module rather than the wiring?

Selective failure. One function stops while the others keep working — the brush will not start but the vacuum runs, or the pump is dead and everything else is fine. Everything failing together points at the supply, the cord, the strain relief or the main switch, all of which are cheaper to fix.
