Tool Won’t Power On? Fast Checks for Festool (Switch, Cord, Module)
Before you assume a dead motor, rule out quick fixes: Plug-It cord, outlet, switch, brushes (where applicable), and speed/control electronics.
🔧 Book Diagnostics — $79.99 (credited if repair approved)📞 Call 214-994-8121
TL;DR: 1) Test a different outlet. 2) Try a known-good Plug-It cord. 3) Cycle the switch and speed dial. 4) Check for tripped breakers, burnt smell, or scorched connectors. If still dead, book diagnostics so we can isolate switch, cord, module/board, brushes, or motor.
Likely Causes (Fast Map)
- 🔌 No power path — bad outlet, tripped breaker, faulty cord or Plug-It connector.
- 🧲 Switch or trigger — worn contacts, dust ingress, safety interlock not engaging.
- ⚡ Electronics — dead speed module/board; tool may show no life at all.
- 🧯 Motor/brushes (where applicable) — worn brushes, seized bearings, thermal cutout.
Two-Minute Triage
- 🔁 Try another outlet or circuit.
- 🔄 Swap to a known-good Plug-It/power lead.
- 🎚️ Set speed dial to mid/high; cycle switch 10–15 times.
- 👃 Smell for ozone/burn; look for heat marks at connectors.
Sanders (RO/ETS/ETS EC/DTS/RTS)
- 🧰 If the pad never “twitches,” suspect cord, switch, or speed module.
- 🧱 Older brushed motors: check brush wear; replace in pairs.
- 🛞 High resistance from seized bearings can trigger thermal cutout.
CT Dust Extractors
- 🧪 Test in Manual at max suction; then retest Auto/Tool.
- 🔌 If Manual runs but Auto won’t, suspect tool socket or board logic.
- 🌡️ If unit clicks but won’t start, inspect cord, switch, and motor protection.
Safe DIY Checks (No Disassembly)
- 🔍 Inspect Plug-It ends for looseness, arcing, or melted plastic.
- 🧼 Blow out dust around switch/selector; cycle to break light oxidation.
- 🔄 Try another cord if available; confirm cord seats fully with a click.
- 🔔 Listen while toggling: any brief chirp or flicker indicates partial contact.
If the tool is still under manufacturer warranty, use the official process. We don’t service in-warranty tools.
Book Diagnostics When: Multiple cords/outlets fail; switch feels “dead”; speed dial has no effect; burnt smell/heat marks; tool trips breakers; CT runs Manual but not Auto. Diagnostic is $79.99 (labor only) and is credited toward your repair if approved. Parts are quoted as needed.
⚠️ Safety: Stop immediately if you see smoke, melted insulation, or smell strong ozone. Do not continue cycling power—this can damage the module or motor further.

FAQs
Could the cord be the only problem?
Yes. Plug-It cables take strain. Try a known-good cord first; it’s the fastest rule-out. My sander lights up but won’t spin—same issue?
Not exactly. That points to speed module, pad brake, or bearings rather than pure power loss. How much is diagnostics?
$79.99 (labor only). If you approve the repair, we apply the diagnostic fee toward it. Parts are quoted after testing.
